Q: In the reaction 2H2 + O2 → 2H2O, how many moles of water are produced from 4 moles of hydrogen?

Solution: According to the stoichiometry of the reaction, 2 moles of H2 produce 2 moles of H2O. Therefore, 4 moles of H2 will produce 4 moles of H2O.

Steps: 8

Step 1: Look at the chemical reaction: 2H2 + O2 → 2H2O.
Step 2: Identify how many moles of hydrogen (H2) are involved in the reaction. The reaction shows that 2 moles of H2 produce 2 moles of water (H2O).
Step 3: Since we have 4 moles of H2, we need to see how many times the 2 moles of H2 fit into 4 moles of H2.
Step 4: Divide 4 moles of H2 by 2 moles of H2 from the reaction: 4 moles H2 ÷ 2 moles H2 = 2.
Step 5: This means we have 2 times the amount of H2 from the reaction.
Step 6: Since 2 moles of H2 produce 2 moles of H2O, then 2 times that amount will produce 2 times 2 moles of H2O.
Step 7: Calculate 2 times 2 moles of H2O: 2 × 2 = 4 moles of H2O.
Step 8: Therefore, 4 moles of H2 will produce 4 moles of H2O.

In the reaction 2H2 + O2 → 2H2O, how many moles of water are produced from 4 moles of hydrogen?
