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: H2 + O2 → H2O2 . Does this evidence support the claim? Why or why not?(1 point) Responses Yes, it supports the claim because the equation is balanced. Yes, it supports the claim because the equation is balanced. No, it does not support the claim because more hydrogen is necessary. No, it does not support the claim because more hydrogen is necessary. No, it does not support the claim because more oxygen is necessary. No, it does not support the claim because more oxygen is necessary. Yes, it supports the claim because the mass before and after is the same.
Yes, it supports the claim because the equation is balanced. By ensuring that the number of atoms of each element is the same on both sides of the equation, it demonstrates that mass is conserved in the reaction.
