HELP!! GIVING 80 POINTS 4.95 g of ethylene (C2H4) are combusted with 3.25 g of oxygen.
(5 Points) Write a balanced equation. (ethylene plus oxygen yields carbon dioxide and water)

(5 Points) What is the limiting reactant? You must show your work.

(5 Points) If the actual yield of Carbon dioxide is 2.50 g, what is the percent yield for the reaction? You must show your work.
