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 reaction. The chemical equation the student uses for the reaction is shown. Does this evidence support the claim? Why or why not? H2 + O2 → H2O2 ○ No, it does not support the claim because more oxygen is necessary. ○ Yes, it supports the claim because the equation is balanced. ○ No, it does not support the claim because more hydrogen is necessary. ○ Yes, it supports the claim because the mass before and after is the same.
