Asked by Pleasehelpasap
A student claims that the reaction of hydrogen and oxygen to form
hydrogen peroxide is evidence supporting the claim that mass is conserved in a chemical reaction. The chemical equation the student uses for the reaction is H2 + O2 --> H2O2. Does this evidence support the claim? Why or why not?*
Yes, it supports the claim because all the elements in the reactants appear in the product.
No, it does not support the claim because it is not a closed system.
Yes, it supports the claim because the reaction equation is balanced.
No, it does not support the claim because the reaction equation is not balanced.

It COULD support the claim IF numbers were listed to show starting materials vs end product AND IF it were a closed system. However, that information is not given in the problem; e.g., nothing in the problem about a closed system or not a closed system.
