Based on the given information, we cannot directly determine the amount of Ag that can be heated. The problem only provides information on the cooling of Au and its specific heat capacity. To solve for the heat lost by Au, we can use the equation:
Q = mcΔT
where Q is the heat lost, m is the mass, c is the specific heat capacity, and ΔT is the change in temperature.
Using the given values for Au, we have:
Q = (22 g) (0.13 J/(g°C)) (95.5°C - 26.4°C)
Q = 213.59 J
Assuming that all the heat lost by Au is transferred to Ag, we can use the same equation to solve for the mass of Ag that can be heated:
Q = mcΔT
213.59 J = m (0.24 J/(g°C)) (36°C - 23°C)
m = 14.1 g
Therefore, 14.1 g of Ag can be heated from 23°C to 36°C using the heat lost by 22 g of Au cooling from 95.5°C to 26.4°C, assuming all the heat lost by Au is transferred to Ag.

22.17 grams of silver can be heated from 23 °C to 36 °C when 22 g of gold cools from 95.5 °C to 26.4 °C.
Determining the grams to be heatedTo solve this problem, we can use the formula:
q = m * c * ΔT
For gold (Au):
q = m * c * ΔT
q = 22 g * 0.130 J/(g °C) * (-69.1 °C)
q = -202.58 J (note the negative sign indicates heat lost)
The heat lost by gold is equal to the heat gained by silver (Ag):
q = m * c * ΔT
202.58 J = m * 0.240 J/(g °C) * (36 °C - 23 °C)
m = 202.58 J / (0.240 J/(g °C) * 13 °C)
m = 22.17 g
Therefore, 22.17 grams of silver can be heated from 23 °C to 36 °C when 22 g of gold cools from 95.5 °C to 26.4 °C.

At the stoichiometric (equivalence) point in a titration of benzoic acid with naoh(aq) shown by equation 3, the ph is:_______
Benzoic acid is one of the weakest acid for titration. The pH of the salt solution generated is the pH greater than 7( >7 ) at the equivalence point in any titration.
The benzoate anion, combines with water to create OH- and undissociated benzoic acid. This reaction is stronger than OH-. As a result of the hydroxide ions generated by this reaction, the final solution has a pH greater than 7. Hydrolysis is the term for an ion's reaction with water, such as the benzoate ion.
What is titration?A titration is a method for figuring out the concentration of an unknown solution by using a solution with known concentration.Until the reaction is finished, the titrant (the known solution) is typically added from a buret to a known volume of the analyte (the unknown solution).The concentration of the unknown can be determined by knowing the amount of titrant that was added.

A. G=-6.5 kJ; nonspontaneous
B. G= 10.5 kJ; spontaneous
C. G= 10.5 kJ; nonspontaneous
D. G=-6.5 kJ; spontaneous
The reaction has a change in free energy of -6.5 kJ and is spontaneous Option D.
What is a spontaneous reaction?The term spontaneous reaction refers to a reaction that occurs with n external input of energy. We know that a spontaneous reaction is one in which the value of the change in free energy is negative. If the change in the free energy is positive then the reaction is nonspontaneous.
If the value of the change in free energy is zero then it follows that the reaction has attained equilibrium.
Now;
ΔG = ΔH - TΔS
ΔH = 2 kJ/mol
T = 500 K
ΔS = 0.017 kJ/(K-mol)
When we substitute values;
ΔG = 2 kJ/mol - (500 K * 0.017 kJ/(K-mol))
ΔG = -6.5 kJ

The percent yield of the calcium hydroxide is 84.5%.
What is stoichiometry?Stoichiometry enables us to obtain the mass of a substance form the equation of the reaction.
The equation of the reaction is;
CaCO3 + 2HCl -----> CaCl2 + CO2 + H2O
Number of moles of X = 40.0 grams/100 g/mol = 0.4 moles
Number of moles of HCl = 850/1000 * 1 M = 0.85 moles
If 1 mole of CaCO3 reacts with 2 moles of HCl
0.4 moles of CaCO3 reacts with 0.4 moles * 2 moles/1 mole
= 0.8 moles of HCl
Hence X is the limiting reactant.
The reaction is 1:1 then the amount of CO2 produced is 0.4 moles
Mass of CO2 = 0.4 CO2 * 44 g/mol = 17.6 g
2) The reaction equation is; 2NaOH + CaCO3 ---> Ca(OH)2 + Na2CO3
Number of moles of X = 25.0 grams/100 g/mol = 0.25 moles
Number of moles of NaOH= 40/1000 L * 2 M = 0.08 moles
If 1 mole of X reacts with 2 moles of NaOH
0.25 moles reacts with 0.25 moles * 2 moles /1 mole
= 0.5 moles
NaOH is the limiting reactant
2 moles of NaOH produces 1 mole of CO2
0.08 moles of NaOH produces 0.08 moles * 1 mole/2 moles
= 0.04 moles of CO2
Theoretical yield of CO2 = 0.04 moles of CO2 * 74 g/mol = 2.96 g

In a complete blood cell (CBC) test, the amount of hemoglobin in the blood is often measured.
A globin group is surrounded by four heme groups, which together form a tetrahedral shape in each hemoglobin molecule. Heme is an organic complex known as a porphyrin that has an iron atom linked to it. Heme makes up only 4% of the weight of the molecule. As the blood circulates between the lungs and the tissues, the iron atom is what holds oxygen in place. Each hemoglobin molecule contains four iron atoms, and as a result, it has the capacity to bind four oxygen molecules. Two linked pairs of polypeptide chains make up globin.

4. 2.376 grams of H2O is formed
Stoichiometric problemFrom the equation: [tex]4NH_3 + 5O_2 --- > 4NO + 6H_2O[/tex]
Mole ratio of NH3 and O2 = 4:5
Mole of 3.25 g NH3 = 3.25/17 = 0.19 mol
Mole of 3.50 g O2 = 3.5/32 = 0.11 mol
Equivalent mole of O2 from NH3 = 5/4 x 0.19 = 0.24 mol
Equivalent mole of NH3 from O2 = 4/5 x 0.11 = 0.088 mol
Thus, O2 is the limiting reagent.
Excess NH3 = 0.19 - 0.088 = 0.102 moles
Mole ratio of O2 and NO = 5:4
Equivalent mole of NO = 4/5 x 0.11 = 0.088 mol
Mole ratio of O2 and H2O = 5:6
Equivalent mole of H2O = 6/5 x 0.11 = 0.132 mol
