Astudent isolated 16 g of a compound following a procedure
that would theoretically yield 39 g. what was his percent yield?

41.03%

Explanation:

From the question;

We are required to determine the percent yield

Thus, in this case;

% yield = (16 g ÷ 39 g)× 100

            = 41.03%

Thus, the percent yield is 41.03%

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
