1. Does this chemical reaction follow the law of conservation of matter? 2. How many atoms of hydrogen do you have in the reactants? How many atoms of hydrogen to you have in the product?

3. Give 1 reason why this chemical reaction/equation follows OR does not follow the law of conservation of matter?

1. By applying the law of conservation of matter on chemical reaction, we can define it as follows: Law of conservation of matter (mass): the sum of reactants masses in any chemical reaction equals the sum of products masses. Achieving the law of conservation of matter in the reaction of magnesium with oxygen, (the atomic masses of Mg = 24, O = 16) 2Mg + O 2 → 2MgO (2× 24) + (2× 16)

2. Mass is conserved in a chemical reaction, so the mass before must equal the mass after. If you have five atoms before, you must have five atoms after.

3.  The equation is not balanced because the law of conservation of matter is not achieved. Second: Law of constant ratios. The chemical compound is produced from a chemical combination of atoms of two elements or more by constant weight ratios.
