How many grams of calcium phosphate
are produced from 26 grams of (Iron Ill)
phosphate and 12.1 grams of calcium
carbonate. what is the excess reactant

Answers

Answer 1

Answer:

A. Excess reactant is FePO4

B. mass of Ca3(PO4)2 produced is 12.41g

Explanation:

A. FePO4 has molar mass of 150.82 g/mol => 26/150.82 = 0.17 mole

CaCO3 has molar mass of 100.09 g/mol => 12.1/100.09 = 0.12 mole

3CaCO3 + 2FePO4 => Ca3(PO4)2 + Fe2(CO3)3

2 moles of FePO4 will react with 3 moles of CaCO3

Therefore,

0.17 mole of FePO4 will react with 0.17 x (3/2) = 0.255 mole of CaCO3

and

0.12 mole of CaCO3 will react with 0.12 (2/3) = 0.08 mole of FePO4

Therefore the excess reactant will be FePO4

B. 3 moles of CaCO3 will produce 1 mole of Ca3(PO4)2

so 0.12 mole of CaCO3 will produce 0.12 x (1/3) = 0.04 mole

Ca3(PO4)2 has molar mass of 310.18 g/mol

=> mass of Ca3(PO4)2 produced is 0.04 x 310.18 = 12.41g

Consider a titration of 20.00mL of 0.7698M butanoic acid (HA, monoprotic acid, Ka=1.52x10^-5) with 14.34 mL of 0.8322M KOH. What is the pH of this solution?

Answers

The helium sample will occupy a volume of 11.12 L if the pressure is reduced to 5.15 atm while maintaining the temperature at 20 °C.

How do monoprotic and diprotic acids differ?

The ability of monoprotic acids to donate one hydrogen atom or proton to their aqueous solution as opposed to diprotic acids to provide two hydrogen atoms or protons is the primary distinction between the two types of acids.

The pressure and volume of a gas are related by the following equation, known as Boyle's law:

P1V1 = P2V2

where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume, respectively.

Using this equation, we can solve for V2:

P1V1 = P2V2

V2 = (P1V1) / P2

Plugging in the values given in the problem, we get:

V2 = (5.79 atm x 9.89 L) / 5.15 atm

Answers

Using the Henderson-Hasselbalch equation, the pH value when no titrant is added is 4.44.

What is the pH of the Adipic solution?

To solve this problem, we need to use the Henderson-Hasselbalch equation:

pH = pKa + log([A-]/[HA])

where;

pH is the pH value,pKa is the acid dissociation constant,[A-] is the concentration of the conjugate base, and[HA] is the concentration of the acid.

We can use this equation to calculate the pH values at different points during the titration.

When no titrant is added:

At this point, we have only the adipic acid in the solution, so we can use the equation:

pH = pKa + log([A-]/[HA])

pH = pKa + log(0/0.1)

pH = pKa = 4.44

pH = 4.44

Answers

Now, we can calculate the percent yield of carbon dioxide using the following equation Percent yield of CO2 = 61.5% .

What is carbon dioxide?

Carbon dioxide (CO2) is a colorless, odorless gas composed of one carbon atom and two oxygen atoms. It exists in the Earth's atmosphere as a trace gas, making up approximately 0.04% of the atmosphere by volume. In nature, it is produced by the respiration of living organisms and through the decay of organic matter.

It is also a byproduct of many human activities such as burning fossil fuels, producing cement, and manufacturing plastic. Carbon dioxide is an important greenhouse gas, which means it absorbs and traps heat in the atmosphere, resulting in global warming.

The given reaction is:

CH3CH2CH3 + O2 → CO2 + H2O

m(octane) = 20.6 g

m(O2) = 98.6 g

m(CO2) = 29.2 g

Using the given information and the balanced equation, we can determine the theoretical yield of carbon dioxide by using the following equation:

m(CO2) (theoretical) = (m(octane) × molar mass of octane) / molar mass of CO2

Assuming the balloon can freely expand, calculate the volume of the balloon at this altitude.

Answers

Answer: 49.67 Liters

Explanation: To solve this problem, we only have to use 1 equation: P1V1/T1=P2V2/T2. P, T, and V represent pressure, temperature, and volume respectively. This equation can be used when dealing with gas problems. Usually, there is some change in pressure, temperature, or volume, that will alter pressure or volume. Temperature does not change with pressure or volume.

We are given the balloon starting at 29.8 L(V1), a pressure of 734 mmHg(P1), and a temperature of 27.9 C(T1). The ballon rises and encounters a new set of conditions: 375 mmHg(P2) and -16.8 C(T2). The only variable we are missing is V2 which we will solve for. But before we plug in, we have to do some unit conversions. When using any ideal gas equation, the temperature has to be in Kelvin, the volume in Liters, and the pressure in atm. To convert from mmHg to atm, we simply divide by 760. To convert from Celcius to Kelvin we add 273. Now we can plug into the equation.

((.9657 atm)(29.8 L))/300.8 K=((.4934 atm)(V2))/256.2 K

((.9657 atm)(29.8 L)(256.2 K))/((300.8 K)(.4934 atm))=V2

V2= 49.67 Liters

Answers

Answer: 51.3 mL.

Explanation:

To calculate the minimum volume of a 2.34 M NaOH solution needed to make 150.0 mL of a 0.800 M NaOH solution, we can use the formula:

M1V1 = M2V2

Where M1 is the initial molarity, V1 is the initial volume, M2 is the final molarity, and V2 is the final volume.

We want to find the initial volume, so we can rearrange the formula to solve for V1:

V1 = (M2V2) / M1

Substituting the given values, we get:

V1 = (0.800 mol/L x 0.150 L) / 2.34 mol/L

V1 = 0.0513 L or 51.3 mL (rounded to 3 significant figures)

Therefore, the minimum volume of a 2.34 M NaOH solution needed to make 150.0 mL of a 0.800 M NaOH solution is 51.3 mL. Answer: 51.3 mL.

Two chemists conduct the reaction and measure a percent yield of carbon dioxide of 89%. IF the actual yield was 22.32 moles of carbon dioxide gas at STP, what was the theoretical yield of carbon dioxide?

Answers

Theoretical yield of CO2 is 25.07 moles.  The percent yield of a reaction is the ratio of the actual yield to the theoretical yield, expressed as a percentage, and is a measure of the efficiency of the reaction.

What is Theoretical Yield?

Theoretical yield is the maximum amount of product that can be obtained from a given amount of reactants, assuming complete conversion of the reactants and 100% efficiency of the reaction. In other words, it is the amount of product that would be obtained if the reaction proceeded to completion without any side reactions or losses of product.

The balanced chemical equation for the combustion of C2H6O (ethanol) is:

C2H6O + 3O2 → 2CO2 + 3H2O

The stoichiometry of the equation shows that 1 mole of C2H6O reacts with 3 moles of O2 to produce 2 moles of CO2. Therefore, the theoretical yield of CO2 can be calculated based on the amount of C2H6O used in the reaction.

Assuming that the percent yield of CO2 is 89%, we can calculate the actual yield of CO2 as follows:

Actual yield of CO2 = 89% x theoretical yield of CO2

If the actual yield of CO2 is 22.32 moles at STP, we can calculate the theoretical yield of CO2 as follows:

Theoretical yield of CO2 = Actual yield of CO2 / (89%/100%)

Theoretical yield of CO2 = 22.32 moles / 0.89 = 25.07 moles

Therefore, the theoretical yield of CO2 is 25.07 moles.

What is the mass of 6.30 moles of magnesium chloride, MgCl2 ?
Express your answer with the appropriate units.

Answers

To calculate the mass of 6.30 moles of MgCl2, we need to find the molar mass of MgCl2 first.

The molar mass of MgCl2 can be found by adding the atomic masses of magnesium and chlorine, which are 24.31 g/mol and 35.45 g/mol respectively. So:

MgCl2: (1 x 24.31 g/mol) + (2 x 35.45 g/mol) = 95.21 g/mol

Now we can use this value to calculate the mass of 6.30 moles of MgCl2:

mass = moles x molar mass
mass = 6.30 mol x 95.21 g/mol
mass = 599.4 g

So the mass of 6.30 moles of MgCl2 is 599.4 g.
To find the mass of 6.30 moles of MgCl2, we need to use the molar mass of MgCl2, which is the sum of the molar masses of magnesium and chlorine.

1. Find the molar mass of MgCl2:
Mg has a molar mass of 24.31 g/mol, and Cl has a molar mass of 35.45 g/mol. Therefore, the molar mass of MgCl2 is 24.31 g/mol + 2(35.45 g/mol) = 95.21 g/mol.

2. Calculate the mass of 6.30 moles of MgCl2:
mass = moles x molar mass = 6.30 mol x 95.21 g/mol = 600.0 g

Therefore, the mass of 6.30 moles of MgCl2 is 600.0 g.

Is it the same ΔrG° and ΔfG° ? Standard free gibbs energy.

Answers

Answer:

Yes. ΔrG° and ΔfG° represent the same thing, namely the standard free Gibbs energy. In the context of thermodynamics, this energy refers to the energy associated with a reaction that is taking place at a given temperature, pressure and concentration of reactants. This energy is dependent on the thermodynamic properties of the substances that are undergoing the reaction, and can be calculated from the reaction enthalpy, entropy and the standard state properties of the participating chemicals.

To further clarify the concept, let's take a look at a simple reaction:

A + B → C + D.

The standard free Gibbs energy for this reaction can be calculated using the following equation:

ΔrG° = ΔH° - TΔS°

Where ΔH° is the standard enthalpy change for the reaction, T is the temperature in Kelvin, and ΔS° is the standard entropy change for the reaction. It is important to note that both ΔH° and ΔS° are given in units of kJ/mol. The resulting ΔrG° can also be expressed in terms of the standard state properties of each participating reactant, resulting in the equation:

ΔrG° = Σi (ni·G°i) = Σi (ni·(H°i - T·S°i))

Where ni is the stoichiometric coefficient of the reactant,

Ksp Ag2CO3 = 8.1*10^-12
Ksp PbCO3 = 7.4*10^-14
Ksp MnCO3 = 8.8*10^-11

Answers

Only Ag2CO3 will precipitate from the solution.

Precipitation reaction

When Na2CO3 is added to the solution, it will react with the Ag^+ and Pb^2+ ions to form precipitates of Ag2CO3 and PbCO3. The Mn^2+ ion concentration is not high enough to form a precipitate with Na2CO3.

First, let's calculate the initial concentration of Ag^+ and Pb^2+ ions in the solution:

Ag^+: 0.00050 M

Pb^2+: 0.00050 M

Next, we need to calculate the concentration of Na2CO3 after it is added to the solution. Since we added 10.00 ml of 1.0*10^-6 M Na2CO3 to a total volume of 500 ml, the final concentration of Na2CO3 is:

[Na2CO3] = (10.00 ml / 500 ml) * 1.010^-6 M

[Na2CO3] = 2.010^-8 M

Now we can use the Ksp values to determine which precipitates will form.

For Ag2CO3:

Ksp = [Ag^+]^2[CO3^2-]

8.110^-12 = (2x)^2 (2x)

8.110^-12 = 4x^3

x = 2.0*10^-4 M

Since the concentration of CO3^2- is higher than the solubility product, Ag2CO3 will precipitate.

For PbCO3:

Ksp = [Pb^2+][CO3^2-]

7.410^-14 = (0.00050 M)(2x)

x = 9.210^-11 M

Since the concentration of CO3^2- is lower than the solubility product, PbCO3 will not precipitate.

Therefore, the only precipitate that will form is Ag2CO3.

[tex]\rm AgNO_3=107.868+14.007+(3 \cdot 15.999)=169.872\;g/mol[/tex]

Calculate the moles of each reactant by dividing the given mass by the molar mass:

[tex]\rm Moles\;of\;Cu=\dfrac{5.00\;g}{63.55\;g/mol}\approx 0.0787\;mol\;(3\;s.f.)[/tex]

Silver nitrate (AgNO₃) is the limiting reactant since we have fewer moles of it.

From the balanced equation, 2 moles of AgNO₃ produces 2 moles of Ag. Therefore, the number of moles of Ag produced is:

[tex]\rm 0.00589 \;mol\;AgNO_3 \times \dfrac{2 \;mol\; Ag}{2 \;mol \;AgNO_3} =0.00589 \;mol\;Ag[/tex]

Why does lowered air pressure allow water to boil at room temperature? A. The mass of the liquid is reduced, making it easier to form a gas. B. The lowered air pressure increases the temperature of the liquid. C. Less force pushes down on the liquid, making it easier for gas to escape. D. The kinetic energy of the liquid molecules increases, causing gas to form.4

Answers

The right response is C. Less pressure is applied to the liquid, which makes it simpler for gas to escape.

Why is it possible for water to boil at room temperature despite the reduced air pressure?

Less pressure allows the water molecules to flow more freely, gaining kinetic energy in the process. As a result, less heat energy is needed to break the intermolecular interactions. (the boiling point decreases). Water boils and transforms into water vapour after the boiling point is reduced to room temperature.

Why does water boil at lower temperatures and lower pressures?

When air pressure is lower, it requires less energy to get water to the boiling point. Water will boil at a lower temperature at higher altitudes because there is less energy and hence less heat there.

a. The estimated gas-phase enthalpy change for the reaction, ΔH is 493 kJ/mol.

b. The reaction is endothermic

c. The spontaneity of the reaction cannot be determined from the given data.

What is the enthalpy change of the reaction?

To estimate the gas phase enthalpy change using bond dissociation enthalpies, we need to calculate the sum of the bond dissociation energies of the bonds broken minus the sum of the bond dissociation energies of the bonds formed.

Using the OWL Table Reference, we can obtain the following bond diwsociation energies:

C-H bond dissociation energy: 413 kJ/mol

S-H bond dissociation energy: 339 kJ/mol

C-S bond dissociation energy: 259 kJ/mol

Breaking the bonds in the reactants requires:

1 C-H bond energy: 413 kJ/mol

1 S-H bond energy: 339 kJ/mol

Forming the bonds in the products releases:

1 C-S bond energy: 259 kJ/mol

Therefore, the estimated gas-phase enthalpy change for the reaction is:

ΔH = (bond energies of reactants broken) - (bond energies of products formed)

ΔH = (413 kJ/mol + 339 kJ/mol) - 259 kJ/mol

ΔH = 493 kJ/mol

b. The estimated gas-phase enthalpy change is positive, hence the reaction requires energy to proceed and is endothermic.

c. To determine whether the reaction is likely to proceed spontaneously in the direction written, we need to consider the Gibbs free energy change (ΔG) of the reaction. The Gibbs free energy change is related to the enthalpy change (ΔH) and the entropy change (ΔS) by the equation:

ΔG = ΔH - TΔS

where T is the temperature in Kelvin.

If the Gibbs free energy change is negative (ΔG < 0), the reaction is spontaneous in the forward direction. If the Gibbs free energy change is positive (ΔG > 0), the reaction is non-spontaneous in the forward direction and spontaneous in the reverse direction. If the Gibbs free energy change is zero (ΔG = 0), the reaction is at equilibrium.

What volume of 0.550 M HCl can be prepared from 35.0 mL of 11.7 M HCl? Responses 1.13 mL 1.13 mL 18.4 mL 18.4 mL

Answers

Answer:

To calculate the volume of 0.550 M HCl that can be prepared from 35.0 mL of 11.7 M HCl, we can use the following formula: M1V1 = M2V2 where M1 is the initial concentration of HCl (11.7 M), V1 is the initial volume of HCl (35.0 mL), M2 is the final concentration of HCl (0.550 M), and V2 is the final volume of HCl that we need to calculate. Rearranging the formula to solve for V2, we get: V2 = (M1V1) / M2 Substituting the given values, we get: V2 = (11.7 M)(35.0 mL) / 0.550 M V2 = 747.27 mL Therefore,
