Question

consider the balanced chemical equation. 2h2(g) + o2(g) → 2h2o(g). how many moles of water can you form from 4 moles of hydrogen and excess oxygen? enter your answer as a whole number. answer

Explanation:

Step1: Identify mole - ratio

From the balanced equation \(2H_2(g)+O_2(g)
ightarrow2H_2O(g)\), the mole - ratio of \(H_2\) to \(H_2O\) is \(2:2 = 1:1\).

Step2: Calculate moles of \(H_2O\)

Given 4 moles of \(H_2\) and excess \(O_2\). Using the mole - ratio, if \(n(H_2)=4\) moles and \(\frac{n(H_2)}{n(H_2O)} = 1\), then \(n(H_2O)=4\) moles.

Answer:

4
