I need ASAP!!!!When I am driving around my Volkswagon I burn (C8H18) or octane in my engine the yield of products (carbon dioxide and water) is 93%. (Hint: oxygen is required)1) Write out a balanced chemical equation showing the combustion of octane.2) If 31.0 g of octane is burned with 31.0 g of oxygen what is limiting if anything?3) What is the mass of carbon dioxide produced (don’t forget about the yield) in this engine given 31.0 g of octane is burned with 31.0 g oxygen?
