27. Final Jeopardy
Why can we change the coefficients of a chemical equation and not the subscripts?
Subscripts tell us how many of each atom make up the molecule. They tell us the IDENTITY of the molecule, which we cannot change.
Coefficients tell us HOW MANY of each molecule are needed for an equation to be balanced and obey the law of conservation of mass.
