Which are the possible reactants of these products? ? 2h2o + o2 a. h2o b. h2o2 c. 2h2o2 d. 2h2o + o2

Option (C) is the correct answer.

Explanation:

When we write a chemical reaction equation then reactants are written on left hand side whereas products are written on right hand side.

And a chemical reaction in which a compound dissociates to given two products is known as a decomposition or dissociation reaction.

For example,

Therefore, is the reactant and both and are the products.

Thus, we can conclude that out of the given options are the possible reactants of these products.
