Question

in the reaction 2h₂(g)+o₂(g) --> 2h₂o(g), what is the mole ratio of o₂ to h₂o? 1:2 1:1 2:2 2:1

Explanation:

Step1: Analyze the balanced chemical equation

The balanced chemical equation is \(2H_{2}(g)+O_{2}(g)\to2H_{2}O(g)\).

Step2: Determine the mole ratio

The coefficient of \(O_{2}\) is \(1\) and the coefficient of \(H_{2}O\) is \(2\). So the mole ratio of \(O_{2}\) to \(H_{2}O\) is \(1:2\).

Answer:

1:2
