Which statement best describes a balanced chemical formula? a. there are the same number of ions on either side of the reaction. b. there are the same molecules on either side of the reaction. c. there are the same number of molecules on either side of the reaction. d. there are the same number of the same kind of atoms on either side of the reaction.

A balanced chemical equation should have same number of same kind of atoms with the same charge on both the sides of reaction.

In other words, a chemical reaction where the number of atoms for each element in the reaction and the total charge on them are the same, for both the reactants and the products is called as a balanced chemical equation.

Also, the mass and the charge should balanced on both sides of the reaction.

1. they vary with a higher number because boiling is way hotter than melting
