Consider the reaction of hydrogen gas and oxygen gas to form water. Determine how many moles of O2 are needed to react with 32 moles of H2.

Volcanoes emit much hydrogen sulfide gas, H2S, which reacts withthe oxygen in the air to form water and sulfur dioxide, SO2. Every69 tons of H2S reacts with 97 tons of oxygen and forms 37 tons ofwater. How many tons of SO2 are formed?
