24. A word equation and a
formula equation are both
qualitative. Although they both
show the reactants and
products of a chemical
reaction, they give no
information about amounts of
reactants or products. A
chemical equation, however,
does show the relative
amounts of the reactants and
products in a chemical
equation.
25. Three indication of a
chemical reaction are the
radiation of heat and light, the
production of a gas, and the
formation of a precipitate.
