What do we mean when we say a chemical reaction is balanced? (several choices can be correct.)
there is an equal number of solids, liquids, and gases on both sides of the reaction arrow.
there is an equal number of products on the right side of the equation as there are reactants on the left side of the
arrow.
the total number of each atom is the same on both sides of the reaction arrow.
the net charge on both sides of the reaction arrow is the same.
