2. Ethane gas is a minor byproduct of pig and cattle farming and is thought to be a contributor to climate change. The combustion of ethane is shown in the reaction:
2 CH (g) + 702 (8) — 4CO2 (g) + 6 H,0 ()
In a closed container, 3.89 grams of ethane was completely combusted in excess oxygen. How many moles of
carbon dioxide was produced? SHOW YOUR WORK!
