Which is the balanced chemical equation for the reaction in which hydrogen and oxygen form water?
Answer and explanation
Correct answer: \(2H_2 + O_2 \rightarrow 2H_2O\)
In a balanced equation, the number of atoms of each element is the same on both sides. In \(2H_2 + O_2 \rightarrow 2H_2O\), there are 4 hydrogen atoms and 2 oxygen atoms on each side. In option B, there are 2 oxygen atoms on the left but only 1 on the right, so it is not balanced.
