Answer:

The answer to your question is C₂H₆O

Explanation:

Data

Molecular formula = C₆H₁₈O₃

Empirical formula = ?

Empirical formula is defined as the simplest ratio of the elements that form part of a molecule.

Process

To find the empirical formula find the greatest common factor of the subscripts.

                             6    18   3   2

                             3      9  3   3

                              1     3    1   3

                                     1

The GCF is 3, so factor 3 of the molecular formula

                         3 ( C₂H₆O)  

The result is the empirical formula C₂H₆O

Final answer:

The empirical formula for C6H18O3 is found by dividing the subscripts by their greatest common divisor, which in this case is 3. This yields C2H6O as the simplest whole-number ratio of the elements in the compound.

Explanation:

The empirical formula of a compound is the simplest whole-number ratio of atoms of each element in the compound. To determine the empirical formula for C6H18O3, we must find the greatest common divisor of the subscript numbers and divide them by that number. The greatest common divisor of 6, 18, and 3 is 3, so we divide each subscript by 3 to get the simplest ratio.

Dividing each subscript by 3, we get:

Carbon (C): 6 ÷ 3 = 2

Hydrogen (H): 18 ÷ 3 = 6

Oxygen (O): 3 ÷ 3 = 1

Therefore, the empirical formula is C2H6O.

OK, This is my thinking, I hope this helps you out.

Let's do problem "a"

Step 1.  Write a balanced equation.

                                       2 HCl  +  Ba(OH)2  -------------->  BaCl2  + 2 HOH  

Step 2.  Underneath the HCl and Ba(OH)2 in the equation write what you are given and what you need to find out.

                                    2 HCl        +       Ba(OH)2  -------------->  BaCl2  + 2 HOH

                                 C = 0.130 mol/L    v = 56 mL

                                  V = ?                   C = 0.109 mol/L

Step 3.  They ALWAYS provide a way to calculate the number of moles of one of the substances.  In this case it is Ba(OH)2 because you have C and V

                         n = C X V            n = 0.109 x 56 = 6.104 millimoles

Step 4.  Use the equation to figure out how many moles of the unknown (HCl) you will need.

               the equation says you need TWICE as many moles as you have of Ba(OH)2.  So you will need 6.104 millimoles x 2 or 12.208 milimoles.

Step 5.  Now that yo have moles and concentration of HCl you can now calculate volume

                  C = n / V, so V = n / C

                                 12.208 millimoles / 0.130 mol/L = 93.9 mL

Use this method for all these kind of problems.  

In B) you will have to convert he g of NaOH into moles by 0.240 / 40.00 g/mol and then following trhe rest of the procedure.

C) is done the same way.  convert the g of Na2SO4 into moles first.

d) is almost the same as a) except this time when you find the moles of Ca(OH)2 you just have to convert the moles into mass by multiplying moles x Molar mass of Ca(OH)2.

Best of luck.

Answer:

The mass of the air is 6920.71g

Explanation:

Step 1:

Data obtained from the question. This includes the following:

Volume (V) = 5.0x10^3 L

Molar Mass of air (M) = 28.98 g/mol

Temperature (T) = 0.2°C

Pressure (P) = 1.07 atm

mass air (m) =?

Number of mole (n) =?

Recall:

Gas constant (R) = 0.082atm.L/Kmol

Step 2:

Conversion of celsius temperature to Kelvin temperature.

K = °C + 273

°C = 0.2°C

K = °C + 273

K = 0.2°C + 273

K = 273.2 K

Therefore, the temperature (T) = 273.2 K

Step 3:

Determination of the number of mole of air.

Applying the ideal gas equation PV = nRT, the number of mole n, can be obtained as follow:

PV = nRT

1.07 x 5.0x10^3 = n x 0.082 x 273.2

Divide both side by 0.082 x 273.2

n = (1.07 x 5.0x10^3)/(0.082 x 273.2)

n = 238.81 moles

Step 4:

Determination of the mass of air. This is illustrated below:

Number of mole of air = 238.81 moles

Molar Mass of air = 28.98 g/mol

Mass of air =.?

Mass = number of mole x molar Mass

Mass of air = 238.81 x 28.98

Mass of air = 6920.71g

Answer:

b) It is either a proton or a neutron

Explanation:

the particle that is labeled with an X is a neutral atom or a proton which is symbolically represented as :

[tex]^A_z}}X[/tex]

where: z = atomic number of the element and it comprises of the number of protons(in the nucleus) and number of electron (in the particle)

A = atomic mass of the element  which is represented as the sum of the protons and neutrons (in the nucleus)

Answer:

Option B is correct.

It is either a proton or a neutron.

Explanation:

The image of the correct question is missing.

I would have attached it, but it might violate the brainly community guidelines.

The image contains a particle labelled as X that contains quarks.

Although, the sub atomic particles of an atom are well known and documented, there are further elementary particles that make up the sub atomic particles. They are more properly referred to as fundamental constituents of matter. They include quarks, leptons etc.

Quarks are fundamental constituents that make up protons and neutrons (The subatomic particles in the nucleus).

There are about six known different types of quarks. And they make up protons and neutrons in combinations.

Hence, it is easy to see why the particle X, that contains quarks, can only be a proton or a neutron.

Answer:

1. H2 is the limiting reactant.

2. 56666.67g ( i.e 56.67kg) of NH3 is produced.

Explanation:

Step 1:

The equation for the reaction. This is given below:

N2 + H2 —> NH3

Step 2:

Balancing the equation.

N2 + H2 —> NH3

The above equation can be balanced as follow :

There are 2 atoms of N on the left side and 1 atom on the right side. It can be balance by putting 2 in front of NH3 as shown below:

N2 + H2 —> 2NH3

There are 6 atoms of H on the right side and 2 atoms on the left side. It can be balance by putting 3 in front of H2 as shown below

N2 + 3H2 —> 2NH3

Now the equation is balanced.

Step 3:

Determination of the masses of N2 and H2 that reacted and the mass of NH3 produced from the balanced equation. This is illustrated below:

N2 + 3H2 —> 2NH3

Molar Mass of N2 = 2x14 = 28g/mol

Molar Mass of H2 = 2x1 = 2g/mol

Mass of H2 from the balanced equation = 3 x 2 = 6g

Molar Mass of NH3 = 14 + (3x1) = 14 + 3 = 17g/mol

Mass of NH3 from the balanced equation = 2 x 17 = 34g

From the balanced equation above,

28g of N2 reacted with 6g of H2 to produce 34g of NH3

Step 4:

Determination of the limiting reactant. This is illustrated below:

N2 + 3H2 —> 2NH3

Let us consider using all the 10kg (i.e 10000g) of H2 to see if there will be any left of for N2.

From the balanced equation above,

28g of N2 reacted with 6g of H2.

Therefore, Xg of N2 will react with 10000g of H2 i.e

Xg of N2 = (28 x 10000)/6

Xg of N2 = 46666.67g

We can see from the calculations above that there are leftover for N2 as only 46666.67g reacted out of 50kg ( i.e 50000g) that was given. Therefore, H2 is the limiting reactant.

Step 5:

Determination of the mass of NH3 produced during the reaction. This is illustrated below:

N2 + 3H2 —> 2NH3

From the balanced equation above,

6g of H2 reacted to produce 34g of NH3.

Therefore, 10000g of H2 will react to produce = ( 10000 x 34)/6 = 6g of 56666.67g of NH3.

Therefore, 56666.67g ( i.e 56.67kg) of NH3 is produced.

Answer:

H2 is the limiting reactant

56.2 kg of NH3 will be formed

Explanation:

Step 1: Data given

Mass of N2 = 50 kg = 50000 grams

Mass of H2 = 10 kg = 10000 grams

Molar mass of N2 = 28.0 g/mol

Molar mass of H2 = 2.02 g/mol

Molar mass NH3 = 17.03 g/mol

Step 2: The balanced equation

N2(g) + 3H2(g) → 2NH3(g)

Step 3: Calculate moles

Moles = mass / molar mass

Moles N2 = 50000 grams / 28.0 g/mol

Moles N2 = 1785.7 moles

Moles H2 = 10000 grams / 2.02 g/mol

Moles H2 = 4950.5 moles

Step 4: Calculate the limiting reactant

For 1 mol N2 we need 3 moles H2 to produce 2 moles NH3

H2 is the limiting reactant.It will completely be consumed (4950.5 moles). Né is in excess. There will react 4950.5 / 3 = 1650.2 moles. There will remain 1785.7 - 1650.2 = 135.5 moles

Step 5: Calculate moles NH3

For 1 mol N2 we need 3 moles H2 to produce 2 moles NH3

For 4950.5 moles H2 we'll have 2/3 * 4950.5 = 3300.3 moles

Step 6: Calculate mass NH3

Mass NH3 = moles NH3 * molar mass NH3

Mass NH3 = 3300.3 moles * 17.03 g/mol

Mass NH3 = 56204 grams = 56.2 kg

B. Wrong because it does not have O2 in the formula. All combustion reactions must have O2.

C. Correct because it is a compound reacting with a compound.

D. Wrong because the reactants did not form a single product. ex. (x + y > xy)

E. Wrong because the equation did not start with a single compound and break down. ex. (xy > x + y)

The missing coefficients for the given chemical equation are found by balancing Al, SO₄, K, and OH groups, resulting in a balanced equation representing a double replacement reaction: Al₂(SO₄)₃(aq) + 6 KOH(aq)
ightarrow 2 Al(OH)₃(aq) + 3 K₂SO₄(aq).

The reaction in question is a classic example of a double replacement reaction, where the cations and anions of two ionic compounds switch places, forming two new compounds. To balance the skeleton equation, we should find the correct stoichiometric coefficients that maintain the conservation of mass for each element.

Start by writing the unbalanced equation with all reactants and products including their states:

Al₂(SO₄)₃(aq) + KOH(aq)
ightarrow Al(OH)₃(aq) + K₂SO₄(aq)

Now balance the elements step by step:

This yields the balanced chemical equation:

Al₂(SO₄)₃(aq) + 6 KOH(aq)
ightarrow 2 Al(OH)₃(aq) + 3 K₂SO₄(aq)

The type of reaction for the balance is option C, which is double replacement.

Answer:

C2H5OH--- aqueous solution contains mostly molecules

Na2SO4---aqueous solution contains ions

HCN ---aqueous solution contains mostly molecules and a few ions

Explanation:

Only strong electrolytes dissociate completely in solution to form ions. Hence aqueous solutions of strong electrolytes comprises of ions which conduct electricity.

Weak electrolyte aqueous solutions contain mostly molecules since they ionize only to a very small extent in solution.

Nonelectrolytes remain molecular in solution and do not conduct electricity at all.

When dissolved in water, nonelectrolytes like ethanol produce primarily molecules, strong electrolytes like Na2SO4 generate only ions, and weak electrolytes like HCN result in a mix of mostly molecules with a few ions.

The type of substances present in a solution can be predicted based on the type of electrolyte. C2H5OH (ethanol), a nonelectrolyte, will mainly form molecules when dissolved in water as it does not ionize. Na2SO4, a strong electrolyte, will fully dissociate in water and produce only ions. HCN (hydrocyanic acid), a weak electrolyte, will produce mostly molecules with a few ions as it only partially ionizes in an aqueous solution.

Answer:

The correct answer is A

We'll have 2.0 moles of magnesium nitride produced  and and excess of 2.0 moles nitrogen gas

Explanation:

Step 1: Data given

Number of moles nitrogen gas (N2) = 4.0 moles

Number of moles magnesium = 6.0 moles

Step 2: The balanced equation

3Mg + N2 → Mg3N2

Step 3: Calculate the limiting reactant

For 3 molesmagnesium (Mg) we need 1 mol nitrogen gas  (N2) to react, to produce 1 mol magnesium nitride (Mg3N2)

Magnesium is the limiting reactant. It will completely be consumed 6.0 moles. Nitrogen is in excess. There will react 6.0 / 3 = 2.0 moles

There will remain 4.0 - 2.0 = 2.0 moles N2

Step4: Calculate moles Mg3N2

For 3 molesmagnesium (Mg) we need 1 mol nitrogen gas  (N2) to react, to produce 1 mol magnesium nitride (Mg3N2)

For 6.0 moles Mg we'll have 6.0 / 3 = 2.0 moles Mg3N2

The correct answer is A

We'll have 2.0 moles of magnesium nitride produced  and and excess of 2.0 moles nitrogen gas

The correct answer is a. 2.0 moles of magnesium nitride are formed when 6.0 moles of magnesium react with 4.0 moles of nitrogen, leaving 2.0 moles of nitrogen unreacted as excess.

The formation of magnesium nitride involves a reaction between magnesium metal and nitrogen gas. Magnesium forms a Mg2+ ion, which is a cation, by losing two electrons. Nitrogen, a non-metal, forms an anion with a charge of 3-. Therefore, the formula for magnesium nitride is Mg3N2, indicating that three magnesium ions react with two nitrogen ions to form one formula unit of magnesium nitride.

The balanced chemical equation for the formation of magnesium nitride is:

3Mg + N2 → Mg3N2

Given that 4.0 moles of nitrogen is reacted with 6.0 moles of magnesium, we can determine the limiting reactant and calculate the product formed. The molar ratio of Mg to N2 in the equation is 3:1, meaning three moles of Mg are required for every mole of N2. Therefore, 6.0 moles of Mg would completely react with 2.0 moles of N2 to produce magnesium nitride. Since we started with 4.0 moles of nitrogen, we have an excess of nitrogen, and magnesium is the limiting reactant.

The result is that all of the magnesium reacts and you would produce 2.0 moles of magnesium nitride with 2.0 moles of nitrogen left over as excess. Hence, the correct answer to the student's question is option a.

Answer: quarter moons

Explanation: Neap tides are especially weak tides. They occur when the gravitational forces of the Moon and the Sun are perpendicular to one another (with respect to the Earth). Neap tides occur during quarter moons. The Proxigean Spring Tide is a rare, unusually high tide.

Neap tides occur during the first and third quarter phases of the moon, when the gravitational forces of the sun and moon work against one another, resulting in a smaller tidal range.

Neap tides occur during the first quarter and the third quarter phases of the moon. Unlike spring tides, which occur during the new moon and full moon phases, neap tides are characterized by small tidal range due to the gravitational forces from the sun and the moon working against each other. During the first and third quarter moon phases, the moon and the sun are at a right angle relative to earth, which results in lower than average tidal bulges, hence causing the neap tides.

Hydrogen azide, HN₃, decomposes on heating by thefollowing unbalanced reaction:

[tex]HN_3(g)\rightarrow N_2(g)+H_2(g)[/tex]

If 3.0 atm of pure HN₃ (g) is decomposed initially,what is the final total pressure in the reaction container? Whatare the partial pressures of nitrogen and hydrogen gas? Assume thatthe volume and temperature of the reaction container are constant.

Answer : The partial pressure of [tex]N_2[/tex] and [tex]H_2[/tex] gases are, 4.5 atm and 1.5 atm respectively.

Explanation :

The given unbalanced chemical reaction is:

[tex]HN_3(g)\rightarrow N_2(g)+H_2(g)[/tex]

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen and nitrogen atoms are not balanced on both side of the reaction.

In order to balance the chemical equation, the coefficient '2' put before the [tex]HN_3[/tex] and the coefficient '3' put before the [tex]N_2[/tex] then we get the balanced chemical equation.

The balanced chemical reaction will be,

[tex]2HN_3(g)\rightarrow 3N_2(g)+H_2(g)[/tex]

As we are given:

The pressure of pure [tex]HN_3[/tex] = 3.0 atm

[tex]p_{Total}=2\times p_{HN_3}=2\times 3.0atm=6.0atm[/tex]

From the reaction we conclude that:

Number of moles of [tex]N_2[/tex] = 3 mol

Number of moles of [tex]H_2[/tex] = 1 mol

Now we have to calculate the mole fraction of [tex]N_2[/tex] and [tex]H_2[/tex]

[tex]\text{Mole fraction of }N_2=\frac{\text{Moles of }N_2}{\text{Moles of }N_2+\text{Moles of }H_2}=\frac{3}{3+1}=0.75[/tex]

and,

[tex]\text{Mole fraction of }H_2=\frac{\text{Moles of }H_2}{\text{Moles of }N_2+\text{Moles of }H_2}=\frac{1}{3+1}=0.25[/tex]

Now we have to calculate the partial pressure of [tex]N_2[/tex] and [tex]H_2[/tex]

According to the Raoult's law,

[tex]p_i=X_i\times p_T[/tex]

where,

[tex]p_i[/tex] = partial pressure of gas

[tex]p_T[/tex] = total pressure of gas  = 6.0 atm

[tex]X_i[/tex] = mole fraction of gas

[tex]p_{N_2}=X_{N_2}\times p_T[/tex]

[tex]p_{N_2}=0.75\times 6.0atm=4.5atm[/tex]

and,

[tex]p_{H_2}=X_{H_2}\times p_T[/tex]

[tex]p_{H_2}=0.25\times 6.0atm=1.5atm[/tex]

Thus, the partial pressure of [tex]N_2[/tex] and [tex]H_2[/tex] gases are, 4.5 atm and 1.5 atm respectively.

The final total pressure in the reaction container remains the same as the initial pressure. The partial pressure of nitrogen gas is 1.15 M multiplied by the total pressure, and the partial pressure of hydrogen gas is three times the partial pressure of nitrogen gas.

To determine the final total pressure and partial pressures of nitrogen and hydrogen gas in the reaction container, we need to use the given information about the equilibrium mixture. From the information provided, the equilibrium mixture at 500 °C contains 1.35 M H2, 1.15 MN2, and 4.12 x 10-1 M NH3.  

Since the volume and temperature of the container are constant, the total pressure in the container remains the same as the initial pressure of 3.0 atm.

The partial pressure of nitrogen gas (N2) can be calculated using its molar concentration and the total pressure using Dalton's law of partial pressures. According to the balanced equation N2(g) + 3H2(g) = 2NH3(g), the moles of N2(g) are equal to the moles of NH3(g). Therefore, the partial pressure of N2(g) is 1.15 M multiplied by the total pressure of 3.0 atm.

The partial pressure of hydrogen gas (H2) can be calculated using its molar concentration and the total pressure. Since there are three moles of H2(g) for each mole of NH3(g) according to the balanced equation, the partial pressure of H2(g) is 3 times the partial pressure of N2(g).

Answer:

The answer to your question is a) N₂     b) 3.04 g of NH₃

Explanation:

Data

mass of H₂ = 2.5 g

mass of N₂ = 2.5 g

molar mass H₂ = 2.02 g

molar mass of N₂ = 28.02 g

molar mass of NH₃ = 17.04 g

Balanced chemical reaction

                3H₂  +  1 N₂   ⇒   2NH₃

A)

Calculate the theoretical yield 3H₂ / N₂ = 3(2.02) / 28.02 = 0.22

Calculate the experimental yield H₂/N₂ = 2.5/2.5 = 1

Conclusion

The limiting reactant is N₂ (nitrogen) because the experimental proportion was higher than the theoretical proportion.

B)

             28.02 g of N₂ -------------------- (2 x 17.04) g of NH₃

               2.5 g of N₂    --------------------   x

                            x = (2.5 x 2 x 17.04) / 28.02

                            x = 85.2 / 28.02

                           x = 3.04 g of NH₃

The new volume of the balloon is approximately 2.33 liters when additional helium is added.

To find the new volume of the balloon, we can use Avogadro's Law, which states that the volume of a gas is directly proportional to the number of moles of gas, provided the temperature and pressure are constant. The formula for Avogadro's Law is:

[tex]\frac{V_1}{n_1} = \frac{V_2}{n_2}[/tex]

where:

We can rearrange the formula to solve for V2:

V2 = (V1 * n2) / n1

Substituting the values, we get:

[tex]V_2 = \frac{(1.90 \, \text{L} \times 0.1130 \, \text{mol})}{0.0920 \, \text{mol}}[/tex]

V2 ≈ 2.33 L

Therefore, the new volume of the balloon is approximately 2.33 liters.

Give me brainliest plz

Answer:

It will have no effect

Explanation:

The loss of tin oxide to evaporation will have no effect on the empirical formula of a compound.

The empirical formula of any compound is the simplest formula of that compound by which the combining atoms can be represented.

This formula is not affect by physical changes.

According to the law of constant composition  "all pure samples of the same compound have the same element in the same proportion by mass".

Regardless of the mass loss or gain of any tin oxide compound, it will have the same empirical and molecular formula. The atoms are still combining in the ratio to give the product.
