What volume of hydrogen will be produced at STP by the reaction of 78.33g of aluminum with excess water

Answers

Answer 1

This problem can be solved in a simplest way, without using Ideal Gas Equation and lengthy calculations.

The balance chemical equation is,

2 Al + 6 H₂O → 2 Al(OH)₃ + 3 H₂

Remember at STP 1 mole of any gas exactly occupies 22.4 L volume.
So,
54 g (2 mole) Al on reaction produces = 67.2 L (3 mole) H₂
Then,
78.33 g of Al will produce = X L of H₂

Solving for X,
X = (78.33 g × 67.2 L) ÷ 54 g

X = 97.47 L of H₂ Gas

Answer 2

Final answer:

To find the volume of hydrogen gas produced at STP from the reaction of 78.33g of aluminum with excess water, calculate the moles of aluminum, convert that to moles of hydrogen gas using stoichiometry, and then use the molar volume at STP to find 97.44 liters of hydrogen gas.

Explanation:

To determine the volume of hydrogen produced at STP (Standard Temperature and Pressure) by the reaction of aluminum with excess water, we first need to write the balanced chemical equation for the reaction.

For aluminum reacting with water yielding aluminum hydroxide and hydrogen gas, the balanced equation is:

2 Al(s) + 6 H₂O(l) → 2 Al(OH)3(aq) + 3 H₂(g)

From this equation, we can see that 2 moles of aluminum produce 3 moles of hydrogen gas. To find the moles of aluminum in 78.33g, we use the molar mass of aluminum (approximately 26.98 g/mol).

Calculate the number of moles of aluminum:
78.33 g Al × (1 mole Al / 26.98 g Al) = 2.90 moles Al.Use stoichiometry to find moles of hydrogen gas formed:
2.90 moles Al × (3 moles H₂ / 2 moles Al) = 4.35 moles H₂.Calculate the volume of hydrogen gas at STP:
At STP, 1 mole of any gas occupies 22.4 liters. Therefore, the volume of hydrogen gas produced is:
4.35 moles H₂ × 22.4 L/mole = 97.44 L of H₂.

Thus, the reaction of 78.33g of aluminum with excess water will produce 97.44 liters of hydrogen gas at STP.

Answers

Molarity is defined as the number of moles of solute in 1 L of solution
molarity of given HCl solution is 2.00 M
this means that there are 2.00 mol of HCl solute in 1 L solution
so if 1000 mL contains - 2.00 mol
then 25.0 mL contains - 2.00 mol / 1000 mL/L x 25.0 mL = 0.0500 mol
number of moles of solute are 0.0500 mol

The number of moles of solute that are present in 25.0 mL of 2.00 M HCl is equal to 0.05 moles.

How do we calculate moles from molarity?

Molarity (M) of any solution is define as the number of moles (n) of solute present in per liter of the solution (V) and represented as:

M = n/V

Given that, Volume of solution = 25mL = 0.025L

Number of moles in 11.82 g gold

Answers

Final answer:

The number of moles in 11.82 g of gold is calculated by dividing the mass of the gold by its molar mass. The atomic weight of gold is approximately 197 g/mol, so the calculation is 11.82 g divided by 197 g/mol.

Explanation:

The calculation of the number of moles in a given mass of a substance is a fundamental concept in chemistry. The number of moles (n) can be determined using the formula:

n = mass (g) / molar mass (g/mol)

For gold (Au), the atomic weight is approximately 197 g/mol, which is its molar mass. Therefore, to find the number of moles in 11.82 g of gold, you divide the mass of the gold by the molar mass of gold as follows:

n = 11.82 g / 197 g/mol

This calculation will give you the number of moles of gold in the sample. The density of gold and Avogadro's number are not directly needed for this calculation, but they are commonly referenced when discussing the properties of elements and the mole concept.

Why are valence electrons important? Why do elements bond? What are two ways elements complete their valence?

Answers

Why are valence electrons important?

Valence electrons are the electrons present farthest from nucleus. These valence electrons are either transferred or shared during a reaction. Some elements like metals donate valence electrons in ionic compound formation, while some like Carbon mutually share thier valence electrons to make a covalent bond. Hence, it is the valence electrons that make any element reactive or unreactive.

Why do elements bond?

Elements react in order to gain stability. This stability is gained in the form of attaining noble gas configuration either by donating, gaining or mutually sharing their valence electrons.

What are two ways elements complete their valence?

The two ways are transfer of electrons and mutual sharing of electrons.

Example:
Sodium looses one valence electron to obtain Noble gas configuration of Neon which is more stable configuration.
Chlorine gains one electrons to obtain Noble Gas configuration of Argon which is more stable configuration.
Carbon mutually shares its four valence electrons with four atoms of Hydrogen having one electron per atom to complete its octet.

Answers

The volume will be 300 ml

Answer:

The new volume of the sample will be 300 milliliteres

Explanation:

We were given the following;

Initial Volume (V1) = 150ml

Initial Temperature (T1) = 300K

Final Temperature (T2) = 600K

Final Volume (V2) = ?

Pressure is held constant.

The law applicable in solving this question is that of Charle's law. This law states that the volume of a fixed mass of gas varies proportional to the temperature at constant pressure.

The formula is given as;

[tex]\frac{V1 }{T1} = \frac{V2 }{T2}[/tex]

Solving for V2. we have;

[tex]V2 = \frac{V1T2}{T1}[/tex]

V2 = ( 150 * 600) / 300

N2 (g) + 3H2 (g) -->2 NH3 (g) The equation above is the equation for the Haber process. In a certain reaction, you start with 3.0 moles of nitrogen and 5.0 moles of hydrogen, How much of the excess reactant will be left over after the reaction?

Answers

This is a type of question that tests your ability to find the limiting reagent, or the component that first runs out in the reaction and limits the continuation of the reaction.

To start, begin by figuring out how many times each component can run the reaction. It takes three moles of H2 to run the reaction “once”, so with five moles of H2, you can run it 1.66 times.

It takes one mole of N2 to run the reaction “once”, so with three moles of N2, you can run it three times. This means that H2 is the limiting reagent (1.66 < 3), and N2 will have excess.

After the reaction is run to completion (1.66 times), 1.33 moles of N2 will remain (1.33 left + 1.66 used = 3, beginning).

Final answer:

H₂ is in excess and N₂ will be completely consumed in the reaction.

Explanation:

According to the balanced equation, 1 mole of N₂ reacts with 3 moles of H₂ to produce 2 moles of NH₃. In this particular reaction, you have 3.0 moles of N₂ and 5.0 moles of H₂. To determine the limiting reactant, you need to compare the moles of each reactant to the stoichiometric ratio. In this case, the ratio of moles of N₂ to H₂ is 1:3. Since you have more moles of H₂ (5.0) compared to the stoichiometric ratio, H₂ is in excess. Therefore, all of the N₂ will be completely consumed and there will be no N₂ left over after the reaction.

Result:
As calculated above,the least electronegativity difference is found between Oxygen and Chlorine which is less than 1.7. Hence, it is not ionic compound or it has least Ionic character.

The pair of O and Cl elements forms a bond with the least ionic character.

The ionic character of the bond depends on the electronegativity difference. The bonds having an electronegativity difference of greater than 1.7 have more ionic character.

(A) In bond between Na and Cl, the electronegativity difference =

Electronegativity of Cl - electronegativity of Na

= 3.16 - 0.93

= 2.23

(B) In bond between K and Cl

= electronegativity of Cl - electronegativity of K

= 3.16 - 0.82

= 2.34

(C) In bond between O and Cl:

= electronegativity of O - electronegativity of Cl

= 3.44 - 3.16

= 0.17

(D) In bond between Mg and Cl:

= electronegativity of Cl - electronegativity of Mg

= 3.16 - 1.31

= 1.85

Suppose you wish to make 0.879 l of 0.250 m silver nitrate by diluting a stock solution of 0.675 m silver nitrate. how many milliliters of the stock solution would you need to use?

Answers

Answer is: 325.5 mL of the stock solution.

c₁(AgNO₃) = 0.675 M.

V₂(AgNO₃) = 0.879 L.
c₂(AgNO₃) = 0.250 M.
V₁(AgNO₃) = ?
c₁ - original concentration of the solution, before it gets diluted.
c₂ - final concentration of the solution, after dilution.
V₁ - volume to be diluted.
V₂ - final volume after dilution.
c₁ · V₁ = c₂ · V₂.
V₁(AgNO₃) = c₂ · V₂ ÷ c₁.
V₁(AgNO₃) = 0.250 M · 0.879 L ÷ 0.675 M.
V₁(AgNO₃) = 0.325 L · 1000 mL = 325 mL.

Final answer:

To make 0.879 l of 0.250 m silver nitrate from a 0.675 m stock solution, use the relationship between initial and final concentrations and volumes (M1V1 = M2V2). By substituting the given values and solving for V1, we can find the needed volume of the stock solution in liters and then convert that volume to milliliters by multiplying by 1000.

Explanation:

To answer this question, we need to use the formula related to molarity (M = moles/liters), which is M1V1 = M2V2. It is a relationship between the initial concentration (M1) and volume (V1) of stock solution and the final concentration (M2) and volume (V2) of dilute solution.

In this case, the student wishes to make 0.879 l (V2) of 0.250 m (M2) silver nitrate by diluting a stock solution of 0.675 m (M1) silver nitrate. Substituting these values into the formula M1V1 = M2V2, we can find the volume of the stock solution needed (V1).

So, the calculation would be: (0.675 M) V1 = (0.250 M)(0.879 L).

To solve for V1, divide both sides by 0.675 M and the result is: V1 = (0.250 M)(0.879 L) / 0.675 M. This gives the volume of the stock solution you need to use in liters. To convert this to milliliters (since the question asked for the volume in milliliters), multiply by 1000.
