Explain the flame in a torch used to cut metal

Reference no: EM13168062

The flame in a torch used to cut metal is produced by burning acetylene (C2H2) in pure oxygen. Assuming the cumbustion of 1 mole of acetylene released 1251 kJ of energy, what mass of acetylene is needed to cut through a piece of steel if the process requires 87.211 x 10^4 kJ of energy?
