What do chemical equations use and what are their products?
chemical reactions use up reactants and produce new substances called products;
What happens to atoms in a chemical equation (element group 1 & group 7)
in a chemical reaction no atoms are lost or made but they are rearranged, and as a result we can write balanced symbol equations showing the atoms involved.
