Calculate the theoretical yield for your reaction. {This is your predicted mass of CuO produced based on the starting mass of CuCO3Cu(OH)2} Identify the Experimental Yield of your reaction (the amount that actually got produced and measured)

Calculate the percent yield of your reaction (refer to the introduction)

Evaluate your percent yield – state at least one legitimate reason your yield could be higher or lower than 100%. Be specific (the experimental error is not specific enough, for example)
