Question

State the law of conservation of mass. Then apply the law to this question: What would be the total
mass of the products of a reaction in which 10 grams of water decomposes into the elements
hydrogen and oxygen
help!!!!

Answer 1

Do you have an idea of what the Law of Conservation of Mass states?

Answer 2

yes.. States that mass is neither created nor destroyed in any ordinary chemical reaction.

Answer 3

10grams

The total mass of reactants would be the same as that of the total mass of the products.

Answer 4

thanks! Aegina. But can u please explain it a little more... thanks :)

Answer 5

So the law of conservation states that mass can neither be created or destroyed. so when you apply this theoretically to a chemical reaction its pretty much saying that no matter what you will always have the equal amount of products to reactants. you start with 10g h2o and end with it.

Answer 6

thanks! Studenttrainee

Answer 7

The law of conservation of mass is that the total mass of the reactants are directly the same as the total mass of the products- none was wasted nor added. In this case 10g of H20 leads to 10g of both H2 and O2.
