Chemical equation - Wikipedia
Formation of chemical reaction A chemical equation consists of the chemical formulas of the reactants (the starting substances) and the chemical formula of the products (substances formed in the chemical reaction). The two are separated by an arrow syol (→, usually read as "yields") and each individual substance''s chemical formula is separated from others by a plus sign.
