A solution contains 43 mEq/L of CI and 11 mEg/L of HPO,2-. The Na concentration in mEq/L is 54 mEg/L. The correct option is d.

A solution is a mixture of a solute and solvent.

The solution contains only Na+ cation.

The anions are Cl- and HPO₄²⁻

The equivalent of ion = number of moles x valence

So, the solution will contain 43 mEq/L of Cl- and 11 mEq/L of HPO₄²⁻

The total mEq of anions in the solution = 43 mEq/L + 11 mEq/L = 54 mEq/L

we know, mEq of anions in the solution neutralize by mEq of cations in the solution

The number of mEq anions = the number of mEq cations. The solution contains 54 mEq of cations, i.e. 54 mEq/L of Na+ concentration.

Thus, the Na concentration in mEq/L is 54 mEg/L. The correct option is d.

The question requires us to calculate how many inches light would travel through glass in 458.9 nanoseconds, given that the speed of light in glass is 2.00x10^8 m/s.

To solve this problem, we'll need to go through the following steps:

1) Calculate the speed of light in inches / nanoseconds, considering that 1 nanosecond = 10^-9 s and 1 meter = 39.37 inches;

2) Calculate how many inches light would travel through glass in 458.9 nanoseconds.

Next, we'll go through the steps above to solve the problem:

1) We can convert the speed of light from meters per second (m/s) to inches per nanosecond (in/ns) in two steps: first, let's calculate the speed of light in in/s:

1 m --------------------------------- 39.37 in

2.00 x 10^8 m ---------------- x

Solving for x, we'll have:

Therefore, 2.00 x 10^8 m/s corresponds to 7.87 x 10^9 in/s.

Now, let's convert the value obtained in in/ns:

1s -------------------- 7.87 x 10^9 in

10^-9 s = 1 ns ------------ y

Solving for y, we'll have:

Therefore, 2.00 x 10^8 m/s corresponds to 7.87 in/ns.

2) Now, we can use the value for speed of light in in/ns to calculate how many inches light would move in 458.9 nanoseconds:

1 ns -------------------- 7.87 in

458.9 ns ------------ z

Solving for z, we'll have:

Therefore, light would travel 3.61 x 10^3 inches in 458.9 ns through glass.

Given:98.1 mL of 5 M potassium hydroxide is mixed with 39.9 mL of 4.5 M Iron (III) acetate resulting in a precipitate of Iron (III) hydroxide.To calculate the theoretical yield in grams of Iron (III) hydroxide, the first step is to balance the chemical equation for the reaction that takes place between potassium hydroxide and iron (III) acetate. 3KOH + Fe(C2H3O2)3 → Fe(OH)3 + 3KC2H3O2The balanced chemical equation for the reaction that takes place between potassium hydroxide and iron (III) acetate can be represented as follows;3KOH + Fe(C2H3O2)3 → Fe(OH)3 + 3KC2H3O2The molar mass of Fe(OH)3 is calculated as follows;Molar mass of Fe(OH)3 = Atomic mass of Fe + (3 x Atomic mass of O) + (3 x Atomic mass of H) = (55.85 g/mol) + (3 x 16 g/mol) + (3 x 1 g/mol) = 106.85 g/molThus the molar mass of Fe(OH)3 is 106.85 g/mol.To determine the theoretical yield of Iron (III) hydroxide we must first determine the limiting reactant (the reactant that is fully consumed in the reaction) among potassium hydroxide and iron (III) acetate.Limiting ReactantIn order to find out the limiting reactant among potassium hydroxide and iron (III) acetate, we will first find out the number of moles of each using the formula;Moles = Concentration x Volume in Liters (L)Moles of KOH = Concentration of KOH × Volume of KOH = 5 M × (98.1 mL/1000 mL) = 0.4905 moles Moles of Fe(C2H3O2)3 = Concentration of Fe(C2H3O2)3 × Volume of Fe(C2H3O2)3 = 4.5 M × (39.9 mL/1000 mL) = 0.17955 molesBased on the balanced chemical equation, the mole ratio of KOH to Fe(C2H3O2)3 is 3:1. Hence, the limiting reactant is Fe(C2H3O2)3 since it is lesser in moles compared to KOH. This means that all of the 0.17955 moles of Fe(C2H3O2)3 will be consumed in the reaction while 0.4905 - (0.17955 x 3) = 0.05145 moles of KOH will be left over after the reaction is complete.The theoretical yield is then calculated using the limiting reactant. We can calculate the number of moles of Fe(OH)3 produced from 0.17955 moles of Fe(C2H3O2)3 using the balanced chemical equation. The mole ratio of Fe(C2H3O2)3 to Fe(OH)3 is 1:1. Hence;Moles of Fe(OH)3 = Moles of Fe(C2H3O2)3 = 0.17955 moles. The mass of Fe(OH)3 is then calculated using the formula;Mass = Number of moles × Molar massMass of Fe(OH)3 = Number of moles of Fe(OH)3 × Molar mass of Fe(OH)3 = 0.17955 moles × 106.85 g/mol = 19.179 gTherefore, the theoretical yield of Fe(OH)3 is 19.179 g.

The theoretical yield of iron (III) hydroxide is 19.19 grams.

The balanced chemical equation for the reaction between potassium hydroxide and iron (III) acetate is:

3 KOH + Fe(C₂H₃O₂)₃ → Fe(OH)₃ + 3 KC₂H₃O₂

To calculate the theoretical yield of iron (iii) hydroxide, first, we determine the limiting reagent.

The number of moles of each reactant:

Number of moles (n) = Molarity (M) × Volume (V)

For potassium hydroxide (KOH):

n(KOH) = 5 M × 0.0981 L

number of moles = 0.4905 moles

For iron (III) acetate (Fe(C₂H₃O₂)₃):

number of moles = 4.5 M × 0.0399 L

number of moles = 0.17955 moles

Since the stoichiometric ratio is 1:1, the number of moles of Fe(OH)₃ = 0.17955 moles.

The molar mass of Fe(OH)₃ = 106.88 g/mol

Theoretical yield = Number of moles × Molar mass

Theoretical yield = 0.17955 moles × 106.88 g/mol

The mass of hydrogen needed to produce 51.0 grams of ammonia is  ≈ 9.07 grams.

To determine the mass of hydrogen required to produce 51.0 grams of ammonia (NH3) using the Haber process, we need to calculate the stoichiometric ratio between hydrogen and ammonia.

From the balanced chemical equation:

3 H₂(g) + N₂(g) → 2 NH₃(g)

We can see that for every 3 moles of hydrogen (H₂), we obtain 2 moles of ammonia (NH₃).

First, we need to convert the given mass of ammonia (51.0 grams) to moles. The molar mass of NH₃ is 17.03 g/mol.

Number of moles of NH₃ = Mass / Molar mass

                     = 51.0 g / 17.03 g/mol

                     ≈ 2.995 moles

Next, using the stoichiometric ratio, we can calculate the moles of hydrogen required.

Moles of H₂ = (Moles of NH₃ × Coefficient of H₂) / Coefficient of NH₃

           = (2.995 moles × 3) / 2

           ≈ 4.493 moles

Finally, we can convert the moles of hydrogen to mass using the molar mass of hydrogen (2.02 g/mol).

Mass of H₂ = Moles × Molar mass

          = 4.493 moles × 2.02 g/mol

          ≈ 9.07 grams

Therefore, approximately 9.07 grams of hydrogen is needed to produce 51.0 grams of ammonia in the Haber process.

Answer:

3

Explanation:

In a nitrogen atom, since the no, of electrons is equal to its no. of protons, it has 7 electrons.

The electron configuration is 2, 5. (the first shell can only hold 2 electrons)

In each covalent bond, 2 electrons are shared between 2 atoms. usually, both atom contribute one electron. (unless it's dative covalent bond, which is not important at this point).

To obey octet rule, the outermost electron shell must have 8 electrons. Which means, the nitrogen atom need 3 more electrons to achieve that.

So with 3 covalent bonds, the nitrogen can get share 3 of its electrons, and obtain 3 more from the other atom(s). It won't lose electrons because covalent bonds exist between shared electrons, unlike ionic bonds.

The mass of chlorine gas product formed is 61.4 g.

What is the mass ?

First, we need to determine which reactant is limiting and which is in excess. To do this, we can use the given mass of HCl and convert it to moles:

63.2 g HCl × (1 mol HCl/36.46 g HCl) = 1.73 mol HCl

Next, we can use stoichiometry to determine how many moles of \(Cl_{2}\) will be produced from 1.73 mol of HCl:

1.73 mol HCl × (2 mol \(Cl_{2}\)/4 mol HCl) = 0.865 mol \(Cl_{2}\)

Finally, we can convert the moles of \(Cl_{2}\) to grams using its molar mass:

0.865 mol \(Cl_{2}\) × (70.91 g \(Cl_{2}\)/1 mol \(Cl_{2}\)) = 61.4 g \(Cl_{2}\)

Therefore, the mass of chlorine gas product formed is 61.4 g.

What is stoichiometry ?

Stoichiometry is a branch of chemistry that deals with the calculation of the quantities of reactants and products involved in a chemical reaction.
