Q
Q: In a reaction where 2 moles of hydrogen react with 1 mole of oxygen, how many moles of water are produced?
Solution:
According to the balanced equation 2H2 + O2 → 2H2O, 2 moles of H2 produce 2 moles of H2O.
Steps: 5
Show Steps
Step 1: Identify the reactants in the reaction. Here, we have hydrogen (H2) and oxygen (O2).
Step 2: Write down the balanced chemical equation for the reaction. The equation is 2H2 + O2 → 2H2O.
Step 3: Look at the coefficients in front of the reactants and products. The coefficient '2' in front of H2 means we have 2 moles of hydrogen.
Step 4: The coefficient '2' in front of H2O means that for every 2 moles of H2, we produce 2 moles of water (H2O).
Step 5: Since we started with 2 moles of H2, we will produce 2 moles of H2O.
