4. For each of the reactions below, calculate the mass (in grams) of the product formed when 2.5 grams of the underlined reactant completely reacts. Assume that there is more than enough of the other reactant. Be sure to balance the reaction first.
a. Ba(s)+ Cl2(g) --> BaCl2(s)
I. Calculate the percent yield if 2.95 g BaCl2is collected.
b. CaO (s)+ CO2(g) --> CaCO3(s)
I. Calculate the percent yield if 0.68 g CaCO3is collected.
c. Mg (s)+ O2(g) --> MgO (s)
I. Calculate the percent yield if 3.25 g MgO is collected.
d. Al (s)+ O2(g) --> Al2O3(s)
I. Calculate the percent yield if 1.89 g Al2O3is collected.
