Q
Q: In the reaction 2H2 + O2 → 2H2O, what is the ratio of moles of hydrogen to moles of oxygen?
Solution:
The balanced equation shows that 2 moles of H2 react with 1 mole of O2, giving a ratio of 2:1.
Steps: 5
Show Steps
Step 1: Look at the chemical equation: 2H2 + O2 → 2H2O.
Step 2: Identify the coefficients in front of H2 and O2. The coefficient for H2 is 2 and for O2 is 1.
Step 3: The ratio of moles of hydrogen (H2) to moles of oxygen (O2) is determined by these coefficients.
Step 4: Write the ratio using the coefficients: 2 (for H2) to 1 (for O2).
Step 5: Simplify the ratio to get 2:1.
