Consider the combustion reaction for acetylene. 2 cap c sub 2 cap h sub 2 l plus 5 cap o sub 2 g rightarrow 4 CO sub 2 g plus 2 cap h sub 2 cap o g If the acetylene tank contains 37 point 0 mol of cap c sub 2 cap h sub 2 and the oxygen tank contains 81 point 0 mol of cap o sub 2 , what is the limiting reactant for this reaction?
