Responses

The H2O and O2 produced have the same mass as the original H2O2.
The H 2 O and O 2 produced have the same mass as the original H 2 O 2 .

The reaction creates new atoms of H2O and O2.
The reaction creates new atoms of H 2 O and O 2 .

Atoms of H2 and O2 are lost during the reaction.
Atoms of H 2 and O 2 are lost during the reaction.

H2O2 has the same properties as H2O and O2.

Answer 1

The correct statement about the reaction is:

**The H2O and O2 produced have the same mass as the original H2O2.**

This statement is true because, according to the law of conservation of mass, the total mass of reactants (2H2O2) must equal the total mass of products (2H2O + O2). Therefore, the mass remains the same in the reaction.

The other statements are not correct:

- The reaction does not create new atoms; it rearranges existing atoms.
- Atoms of H2 and O are not lost; they are conserved in the reaction.
- H2O2 has different properties than H2O and O2.
