question:

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_ The Law of Conservation of Mass applies as the total mass of the products is equal to the total mass of the reactants. So yes

2_In chemical equations, the number of atoms of each element in the reactants must be the same as the number of atoms of each element in the products. 

3_The Law of Conservation of Mass tells us that matter is neither created nor destroyed during a chemical reaction.

the correct answer would be 6 feet.
