Questions & Step-by-Step Solutions

In the reaction 2H2 + O2 → 2H2O, how many liters of H2O vapor are produced from 4 liters of H2?
  • Step 1: Look at the chemical equation: 2H2 + O2 → 2H2O.
  • Step 2: Identify the ratio of H2 to H2O in the equation. For every 2 liters of H2, 2 liters of H2O are produced.
  • Step 3: Since the ratio is 1:1, this means that 2 liters of H2 will produce 2 liters of H2O.
  • Step 4: Now, if we have 4 liters of H2, we can use the same ratio. 4 liters of H2 will produce 4 liters of H2O.
  • Step 5: Therefore, the answer is that 4 liters of H2 produces 4 liters of H2O vapor.
