The given question is incomplete. The complete question is :

Bonding between two elements of equal electronegativity would be

a.100% covalent

b.50% ionic

c. metallic in character

d. primarily ionic

Answer: a. 100% covalent

Explanation:

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element or the metal and the element which accepts the electrons is known as electronegative element or non metal.

A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals. When the two non metals have equal electronegativities, the bond is called as non polar covalent.

Metallic bonding is the type of chemical bonding occurs between the atoms of a metals.In this type of bonding arises due to electrostatic interaction between the electron cloud of de-localized electrons with positively charges metal ions.

Final answer:

A bond between two elements with equal electronegativity is termed a pure or nonpolar covalent bond, characterized by equal sharing of electrons without charge separation on the molecule.

Explanation:

Bonding between two elements of equal electronegativity results in a pure covalent bond, also known as a nonpolar covalent bond. This type of bond forms when electrons are shared equally between the atoms. Since there is no significant difference in electronegativity, there are no stable regions of net negative or positive charge on the molecule's surface, meaning the bond is nonpolar.

Final answer:

The correct formula for iron (III) oxide is [tex]Fe_{2}O_{3}[/tex], where the subscript numbers indicate the ratio of iron to oxygen atoms required to balance the charges of the iron cations and oxide anions in the compound.

Explanation:

The formula for the binary compound iron (III) oxide is [tex]Fe_{2}O_{3}[/tex]. This compound is composed of iron and oxygen, where iron has a +3 oxidation state, known as iron (III). The correct formula is obtained by balancing the charges of the iron cations and oxide anions.

To balance the charges, we need two iron (III) cations (each with a charge of +3) to combine with three oxide anions (each with a charge of -2) to achieve electrical neutrality. The formula reflects the smallest whole number ratio of ions. Therefore, for every two iron ions, there are three oxide ions, giving us [tex]Fe_{2}O_{3}[/tex], which makes answer (d) the correct choice.

Answer: carbonic acid

The given reaction is a synthesis reaction which will generate approximately 45.5g of NaCl, following conversion from moles to grams.

The reaction in question is a synthesis reaction between sodium (Na) and chlorine (Cl_2) to produce sodium chloride (NaCl). The balanced chemical equation for this reaction is 2Na + Cl_2 → 2NaCl, which tells us that the ratio of moles of sodium to moles of sodium chloride is 1:1. Thus, the moles of sodium is equal to the moles of sodium chloride produced.

To calculate this, you would first need to convert grams of sodium to moles using its molar mass (approximately 23 g/mol). Therefore, 18.0 g of Na equals about 0.78 moles. Since the ratio of Na to NaCl in the reaction is 1:1, this means that the reaction would yield 0.78 moles of NaCl.

To convert this to grams, you multiply by the molar mass of NaCl (approximately 58.44 g/mol). So, approximately 45.5g of NaCl would be produced from 18.0 g of Na and sufficient Cl_2

Answer:

31.5 mL of a 2.50M NaOH solution

Explanation:

Molarity (M) is an unit of concentration defined as moles of solute (In this case, NaOH), per liter of solvent. That is:

Molarity = moles solute / Liter solvent

If you want to make 525mL (0.525L) of a 0.150M of NaOH, you need:

0.525L × (0.150mol / L) = 0.07875 moles of NaOH

If you want to obtain these moles from a 2.50M NaOH solution:

0.07875mol NaOH × (1L / 2.50M) = 0.0315L = 31.5 mL of a 2.50M NaOH solution

Answer:

The correct answer is 31.5 ml

Explanation:

We have to dilute the more concentrated solution (2.50 M) to obtain a solution with a molarity of 0.150 M. We have the following data:

Initial concentration = Ci = 2.50 M

Final concentration = Cf = 0.150 M

Final volume = Vf = 525 ml

We consider the final and initial states and use the following expression to calculate the initial volume (Vi) in ml:

Ci x Vi = Cf x Vf

Vi= (Cf x Vf)/Ci = (0.150 M X 525 ml)/2.50 M = 31.5 ml

Increasing temperature increases the reaction rate by increasing the speed of particles. Although increasing concentration and increasing surface area can also speed up a reaction, they do so by increasing the probability of collisions, not particle speed.

The three factors you have listed, namely, increasing concentration, increasing temperature, and increasing surface area, are indeed factors that can increase the rate of a chemical reaction. However, if we're specifically looking at the factor that increases the reaction rate by increasing the particle speed, then the answer would be increasing temperature.

Increasing the temperature causes particles to move faster, and because they're moving faster, they're more likely to collide with each other and react.

On the other hand, increasing concentration increases the number of reactant particles in a given volume, hence, increasing the chance of collisions. Whereas, increasing the surface area of solid reactants increases the area available for collisions to occur. Both will result in a higher rate of reaction, but not by specifically increasing particle speed.

Answer:

P2≈393.609Kpa so I think the answer is 394 kPa

Explanation:

PV=mRT Ideal Gas Law

m and R are constant because they dont change for the problem. That means

PV/T=mR = constant

so P1*V1/T1=P2*V2/T2 and note that the temperatures are in absolute temperatures (Kelvin) because you can't divide by zero.

So P2 = P1*V1*T2/(V2*T1) = 101325 Pa * 700 mL * 303K/(200 mL*273K)

P2 = 393609 Pa

Answer:

3.94 x 10⁵ pascals

Explanation:

combined gas law problem

P₁V₁/T₁ =  P₂V₂/T₂ => P₂ = P₁(V₂/V₁)(T₁2T₁)

P₁ = 1 atm at STP       P₂ = unknown

V₁ = 700 ml               V₂ = 200 ml

T₁ = 0°C = 273K        T₂ = 30°C = 303K

P₂ =  1atm(700ml/200ml)(303K/273K) = 3.89 atm

Answer:

Explanation:

find the solution below.

Phosphorous acid (H3PO3), a diprotic oxyacid, has points of pH change that will happen at equimolar points of the titration with a base of equal concentration (KOH). The pH will vary depending upon the pKa values

The subject in question pertains to Chemistry, specifically acid-base titrations. Here Phosphorous acid ( H3PO3 ), a diprotic oxyacid , is being titrated with an equal concentration base which is Potassium Hydroxide (KOH). A diprotic acid is an acid that can donate two protons per molecule.

In the given scenario, since the concentrations of the acid and the base are the same, the points of pH changes will happen at the equimolar points of the titration. Thus, the first equivalence point will be when 50.0 mL of KOH is added, and the second equivalence point will be at 100.0 mL of KOH.

How much the pH changes after the addition of each portion of KOH depends on the pKa values. After 50.0 mL of KOH (but before 100.0 mL), the major species is HPO3^2- (pKa2 = 6.7). So, the pH should be approximately equal to this value. After 100.0 mL of KOH, the phosphorous acid has been fully neutralized, so the solution now contains mostly OH-, and the pH should be high, depending on how much extra OH- is in solution.

Answer:

Your answer is number A.

Why is it that answer:

When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water.

Ice is less dense than water due to the open crystalline structure formed by hydrogen bonds when water freezes, resulting in gaps between molecules and an increased volume.

Ice is less dense than water because of the hydrogen bonds that form when water freezes. At lower temperatures, water molecules slow down sufficiently to allow hydrogen bonds to hold the water molecules in a crystalline lattice. Ice crystallizes with an open structure, creating gaps between the molecules, which increases the volume of ice compared to liquid water. This unique molecular arrangement in ice causes it to have a density of approximately 0.92 g/cm³, compared to fresh water's density of 1.0 g/cm³. The expansion of ice relative to liquid water is critical as it allows ice to float, forming a surface layer that insulates the water below and enables aquatic life to survive during cold seasons.

temperature changes to 293 K.

3 Determine the number of moles of CO₂(g) in the submarine cabin at which the air

becomes unsafe to breathe. The gram-formula mass of CO₂ is 44.0 g/mol.

4 Convert the original air pressure in the cabin of the submarine to atmospheres.

Answer:

1) The average kinetic energy of the gas molecules will decrease

2) P₂ = 293 K × 116 kPa/312 K = 108.94 kPa

3) 49 mols

4) 116 kPa  = 1.145 atm

Explanation:

(1) When the cabin temperature decreases, the pressure within the cabin will decrease because the average kinetic energy of the gas molecules will decrease. That is the gas particles will have a lower speed.

(2) P₁V₁/T₁ = V₂P₂/T₂

Since the volume is constant we have

116 kPa/312 K = P₂/293 K

P₂ = 293 K × 116 kPa/312 K = 108.94 kPa

(3)  

Since CO₂ is 44.0 g/mol, we have

2156/44 = 49 mols

(4) 1 atm = 101325 Pa

Therefore 116 kPa = 1/101325 ×116000 = 1.145 atm

Answer : The final temperature of balloon will be, 907 K

Explanation :

Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

Mathematically,

[tex]\frac{V_1}{T_1}=\frac{V_2}{T_2}[/tex]

where,

[tex]V_1\text{ and }T_1[/tex] are the initial volume and temperature of the gas.

[tex]V_2\text{ and }T_2[/tex] are the final volume and temperature of the gas.

We are given:

[tex]V_1=2.3L\\T_1=25^oC=(25+273)K=298K\\V_2=7L\\T_2=?[/tex]

Putting values in above equation, we get:

[tex]\frac{2.3L}{298K}=\frac{7L}{T_2}\\\\T_2=906.95K\approx 907K[/tex]

Therefore, the final temperature of balloon will be, 907 K

Final answer:

To expand a 2.3 liter balloon to 7 liters at constant pressure, the temperature must be increased to approximately 630.20°C. This calculation is done using Charles's Law by setting up a proportion between initial and final volumes and temperatures and then converting the final temperature from Kelvins to Celsius.

Explanation:

To determine how hot a 2.3 liter balloon will have to get to expand to a volume of 7 liters, we can use Charles's Law. Charles's Law states that at constant pressure, the volume of a gas is directly proportional to its temperature in Kelvins. First, we convert the initial temperature of 25°C to Kelvins: 298.15 K (since 25 + 273.15 = 298.15). We then set up the proportionality constant using the initial conditions: V1 / T1 = V2 / T2. Substituting in our known values:

2.3 L / 298.15 K = 7 L / T2

Solving for T2 we get:

T2 = (7 L * 298.15 K) / 2.3 L

Calculating this we find T2 is approximately 903.35 K. However, to answer the question, we need to give the final temperature in degrees Celsius. Therefore, we subtract 273.15 from our final temperature in Kelvins: 903.35 K - 273.15 = 630.20°C. This is the temperature to which the balloon must be heated for it to expand to 7 liters.

Answer:

Theoretical yield of P4O10 is 568g

Explanation:

Step 1:

The balanced equation for the reaction. This is illustrated below:

P4(s) + 5O2(g) → P4O10(s )

Step 2:

Determination of the limiting reactant.

From the balanced equation above, 1 mole of P reacted with 5 moles of O2.

Therefore, 3 moles of P will react with = 3 x 5 = 15 moles of O2.

We can see that a higher amount of O2 than what was given is needed to react with 3 moles of P. Therefore, O2 is the limiting reactant.

Step 3:

Determination of the theoretical yield of P4O10.

In this case the limiting reactant is used as it will produce the maximum yield of the reaction. The limiting reactant is O2. The theoretical yield of P4O10 is obtained as follow:

From the balanced equation above, 5 moles of O2 produced 1 mole P4O10.

Therefore, 10 moles of O2 will produce = (10 x 1) /5 = 2 moles of P4O10.

Next, we'll convert 2 moles of P4O10 to grams to obtain the desired result. This is illustrated below:

Number of mole of P4O10 = 2 moles

Molar Mass of P4O10 = (31x4) + (16x10 = 124 + 160 = 284g

Mass of P4O10 =?

Mass = mole x molar Mass

Mass of P4O10 = 2 x 284

Mass of P4O10 = 568g

Therefore, the theoretical yield of P4O10 is 568g.

Final answer:

The theoretical yield of phosphorus(V) oxide when 3 moles of phosphorus react with 10 moles of oxygen is 2 moles, with oxygen being the limiting reactant based on the stoichiometry of the reaction.

Explanation:

The question involves the reaction between phosphorus (P) and oxygen (O₂) to form phosphorus(V) oxide (P₄O₁₀). According to the balanced chemical equation, P₄ (s) + 5 O₂ (g) → P₄O₁₀ (s), 1 mole of phosphorus reacts with 5 moles of oxygen to produce 1 mole of phosphorus(V) oxide. To calculate the theoretical yield of phosphorus(V) oxide, we first determine the limiting reactant, which is the reactant that will be completely consumed first and thus limits the amount of product formed.

In this scenario, 3 moles of phosphorus are reacted with 10 moles of oxygen. Since phosphorus requires 5 moles of oxygen for every mole of phosphorus, 3 moles of phosphorus would require 15 moles of oxygen for a complete reaction. However, only 10 moles of oxygen are available, making oxygen the limiting reactant. Therefore, the theoretical yield of phosphorus(V) oxide would be based on the amount of oxygen available.

Since 5 moles of oxygen react with 1 mole of phosphorus to produce 1 mole of phosphorus(V) oxide, 10 moles of oxygen would react with 2 moles of phosphorus to produce 2 moles of phosphorus(V) oxide. Therefore, the theoretical yield of phosphorus(V) oxide using 10 moles of oxygen is 2 moles of phosphorus(V) oxide.

A 1.0-liter aqueous solution with a pH of 5.0 contains 100 times more hydronium ions than a solution with a pH of 7.0, since the pH scale is logarithmic and a change of 1 unit corresponds to a tenfold change in ion concentration.

The question concerns the comparison of hydronium ion concentrations in aqueous solutions with different pH levels. To analyze the difference between a pH of 7.0 and a pH of 5.0, we need to understand that the pH scale is logarithmic; a change of 1 unit on the pH scale corresponds to a tenfold change in hydronium ion concentration.

For a solution with a pH of 7.0, which is neutral, the concentration of hydronium ions is 1.0 × 10-7 M. An acidic solution with a pH of 5.0 has a higher concentration of hydronium ions because each unit decrease in the pH value corresponds to a tenfold increase in [H3O+]. So, moving from a pH of 7.0 to a pH of 5.0 (a difference of 2 pH units), the hydronium ion concentration increases by a factor of 10 for each unit decrease in the pH. This means that a pH of 5.0 represents a hydronium ion concentration that is 10 × 10 or 100 times greater than that of a solution with a pH of 7.0.

Therefore, compared to a 1.0-liter aqueous solution with a pH of 7.0, a 1.0-liter aqueous solution with a pH of 5.0 contains 100 times more hydronium ions. Hydroxide ions are not directly mentioned in this comparison, but if they were, their concentration would be 100 times less, as they are inversely related to the concentration of hydronium ions.

Pressure 1 = P1 = 1                                  Pressure 2 = P2 = ?

Process

1.- To solve this problem use the Combined gas law

                          P1V1/T1 = P2V2/T2

-Solve for P2

                           P2 = P1V1T2 / T1V2

-Substitution

                          P2 = (1)(24)(298) / (263)(35)

-Simplification

                          P2 = 7152 / 9205

-Result

                          P2 = 0.777

   or                    P2 = 0.78 atm

The final pressure of the gas is 0.686 atm.

To determine the final pressure of the gas, we can use Boyle's Law, which states that for a fixed amount of gas at a constant temperature, the product of the initial pressure and initial volume is equal to the product of the final pressure and final volume. In this case, we can write:

P1V1 = P2V2

Substituting the given values:

(1.00 atm)(24.0 L) = P2(35.0 L)

Solving for P2:

P2 = (1.00 atm)(24.0 L) / (35.0 L) = 0.68571 atm (rounded to 3 sig figs)
