Repоrt yоur аnswer tо eаch question or problem below. Mаke sure you reference your answers by numbering them according to the question or problem. Information that may be useful: molar mass of CaCO3 = 100.1 g/mol molar mass of CO2 = 44.0 g/mol R = 0.0821 L atm K-1 mol-1 1. Reactant A gives products B and C according to the chemical equation below. Reactant A has a molar mass of 323.54 g/mol. Product B has a molar mass of 425.78 g/mol. If 5.00 g of A yields 9.65 g of B, what is the percent yield of B for the reaction? Show all calculations. (3 pts) 2 A ---> 3 B + C 2. What is the molar mass of product C in Question 1? You do not need to show calculations. (1 pt) 3. CaCO3 (s) reacts with HCl (aq) to produce H2O (l), CaCl2 (aq), and CO2 (g). Write a balanced total ionic equation for this reaction. This equation must be perfectly correct and formatted to receive any credit. (3 pts) 4. 3.21 g of CaCO3 reacts with excess HCl and the resulting gas from the reaction is collected into a container having a volume of 524 mL. What is the percent yield of the reaction if the pressure in the container is 1.05 atm at 25.0 0C after completion of the reaction? Assume the starting pressure in the container is negligible. Show all calculations. (3 pts)
