Calcium carbide (CaC2) is produced when CaO, known as quicklime, reacts with carbon at high temperature. CaO(s)+3C(s)CaC2(s)+CO(g)rH=+445kJ/mol If 10.9g of carbon (12.01g/mol) are allowed to react with excess CaO, how much heat is absorbed or released by the reaction? (Give your answer in kJ but do not include units. Be sure that the sign of your answer indicates whether energy is being absorbed or released. Provide at least 3 significant digits. The numbers have been changed from their actual values for the purposes of this question.) Your
