Final answer:

The equation 2H₂ + O₂ → _________________ is balanced and the correct answer is A) H₂O.

Step-by-step explanation:

In a chemical equation, 2H₂ + O₂ → 2H₂O, the correct answer is a) H₂O. This is because combining two molecules of hydrogen gas (H₂) with one molecule of oxygen gas (O₂) produces two molecules of water (H₂O). The equation is balanced because the number of atoms of each element is the same on both sides.
