Step 1: Balance the equation: CH2 + O2 → CO2 + H2O Remember: Mole ratios come from balanced equations only.
1. 2.4 x 10particles of oxygen are used up in the reaction. How many
moles of carbon dioxide (CO2) are produced?
2. How many moles of oxygen does it take to produce 9.60 x 102
molecules of carbon dioxide (CO)?
3. How many moles of carbon dioxide (CO) are produced with using
3.50 x 10” particles of acetylene (CH)?
4. How many molecules of oxygen (O2) does it take to produce 18 moles
of water (H20)?
5. How many moles of acetylene (CH) does it take to produce 12.5 x
10% moles of water (H20)?
