Question: In the reaction 2H2 + O2 → 2H2O, how many liters of H2O vapor are produced from 4 liters of H2?

Options:

Correct Answer: 8 L

Solution:

4 L of H2 produces 4 L of H2O vapor at STP.

In the reaction 2H2 + O2 → 2H2O, how many liters of H2O vapor are produced from 4 liters of H2?

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.

Stoichiometry – The relationship between the quantities of reactants and products in a chemical reaction, particularly in terms of volume for gases at STP.
Gas Laws – Understanding that at standard temperature and pressure (STP), equal volumes of gases contain equal numbers of molecules.
