Silver Nitrate and Calcium Chloride
By: Sam Sullivan
2AgNO3 (aq) + CaCl2 (aq) --> 2AgCl (s) + Ca(NO3)2 (aq)
AgNO3 = 169.87g/mol
CaCl2 = 110.98g/mol
AgCl = 143.32g/mol
Ca(NO3)2 = 164.088g/mol

Limiting and Excess Reactant
For limiting and excess reactant problems, it will usually have 2 givens so we will use the same formula from mass to mass conversions and the lesser product will determine the limiting reactant and the bigger product will determine the excess reactant. In this problem, AgNO3 was the limiting reactant while CaCl2 was the excess reactant because of the amount their respective products had.
The Theoretical Yield is how much product will be created in ideal conditions. To determine theoretical yield, look at the answers to the problem we just solved above. It is the lesser product out of the two answers.
