The balanced molecular equation is: A single-replacement reaction is one in which an element replaces another element in a compound. Some other double-replacement reactions do not produce a precipitate as one of the products. Mass is conserved rather than created or destroyed so when a chemical equation is written, it must be balanced so that there is the same amount of reactants going in as yielded product. 3. ml X.
