I think the correct answer from the choices listed above is the last option. Hydrogen gas (H2) and oxygen gas (O2) react to form liquid hydrogen peroxide (H2O2). The atoms of the reactants have combined to form a new substance. The new substance has its own set of properties that is different from the properties of each reactant.
