Johnny had a balloon filled with 0.222 moles of hydrogen gas. When his lab partner Marisa lit the balloon with a candle on the end of a long stick it burst into a fireball making water. Johnny and Marisa realized that the hydrogen in the balloon reacted with the oxygen in the air to make water according to the equation:
2H2 + O2 --> 2H2O
Their teacher asked them to find out how many moles of oxygen were burned and how many moles of water were formed.
