How can scientists use their knowledge of chemical reactions?

Scientists use chemical equations to summarize what happens in chemical reactions. In chemical equations, reactants and products are represented by chemical symbols and formulas. Numbers called coefficients are placed in front of the symbols and formulas to show how much of each substance is involved in the reaction.
