Johnny had a balloon filled with.404 g 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 --> 2H20
Their teacher asked them to find out how many moles of oxygen were burned and how many moles of water were produced formed.
