#2C_2H_2(l) + 5O_2(g) -> 4CO_2(g) + 2H_2O(g)# If the acetylene tank contains 37.0 mol of #C_2H_2# and the oxygen tank contains 81.0 mol of #O_2#, what is the limiting reactant for this reaction?
We might repropose the combustion reaction as...
…(I use the half-integral coefficients, because I find the arithmetic EASIER this way). And so each equiv acetylene requires

Note that welders can generally adjust the oxygen supply to their acetylene torches, and get reducing or oxidizing flames...
