The coefficients in the balanced equation show the number of moles. They indicate the relative amounts of reactants and products that participate in a chemical reaction. For instance, if we have the balanced equation:
2H2 + O2 → 2H2O
It means that 2 moles of hydrogen gas react with 1 mole of oxygen gas to produce 2 moles of water. The coefficients 2, 1, and 2 represent the number of moles of each substance involved in the chemical reaction.
In balanced equations, we use "moles" to measure "representative particles". What numbers in the balanced equation show the number of moles?
