There is some small loss of matter in a chemical reaction. It is not significant for the purposes of chemistry. Use E=mc^2 to see why the amount is insignificant. Since c^2 is such a huge number, the amount of energy produced in a chemical reaction is equal to a very small amount of mass.
The law should be that the total of mass + energy is conserved. If mass were always conserved, the sun wouldn't work. The sun gives us energy made from matter E=mc^2. But this is a nuclear reaction, not a chemical one.

no matter what the reaction is, the amount of mass/matter will not change in the end product

matter can neither be created now destroyed. it always exist in the form of matter or is converted to energy. if you burn down a tree it is not destroyed but is converted to heat energy.
