When chemists write out reactions, they often place numbers to the left of a chemical formula. e. g. the first 2 in: 2h+o--> h2o. what do these numbers to the left of chemical formulas mean? what information do they provide? they tell us how many of the entire molecule to their right there are involved in the reaction. they tell us how many of the first element of the molecule to their right there are in the entire molecule. they tell us the overall electrical charge of the entire molecule to their right.
