Question

What's the problem with the chemical equation shown?

A. There's a missing oxygen in the product.
B. There's a missing hydrogen in the reactants.
C. There's an additional oxygen in the product.
D. There's an additional hydrogen in the reactants.

Answer 1

A- there’s a missing oxygen in the product; there are 2 oxygen molecules in the reactant hence there should be 2 oxygen molecules in the product

Answer 2

B is actually incorrect. It’s A. There’s 2 Oxygen in the reactant but only 1 in the product. There needs to be an additional oxygen in the product. The answer is A.
