For many chemical reactions, the actual yield is usually less than the theoretical yield. This is due to possible loss in the process or inefficiency of the chemical reaction.
Theoretical yield is obtained from stoichiometry calculation of a balanced equation. Actual yield is the amount of product formed from a reaction. Percentage yield is the ratio of actual yield to the theoretical yield of a product. Percentage yield is never 100 % or greater than 100%. Therefore, Actual yield of a product always less than the theoretical yield.
Stopwatches versus clocks. To improve reliability repeat the experiment multiple times according to an identical procedure. Record these steps so the experiment can be repeated at any time
Vinyl chloride is an organochloride with the formula H2C=CHCl that is also called vinyl chloride monomer (VCM) or chloroethene. This colorless compound is an important industrial chemical chiefly used to produce the polymer polyvinyl chloride (PVC).
