oxyacetylene torches produce such high temperature that they are often used to weld and cut metal. when 1.91 g of acetylene (c2h2) is burned in a bomb calorimeter with a heat capacity of 8.56 kj/k, the temperature increases from 22.213°c to 35.473°c. what is δe (in kj/mol) for this combustion reaction? enter to 0 decimal places.
