1. Using the enthalpies of formation given below, calculate Hrn in kJ, for the following reaction. Report your answer to two decimal places in standard notation. 2Cu2O(s)+C(s)4Cu(s)+CO2(g) Cu2O(s):170.71kJ/molC(s):0.00kJ/molCu(s):0.00kJ/molCO2(g):393.51kJ/mol Tries 0/5 2. Calculate the amount of heat absorbed/released (in kJ) when 2.74 grams of Cu are produced via the above reaction. Report your answer to two decimal places, and use appropriate signs to indicate heat flow direction
