G A scientist measures the standard enthalpy change for the following reaction to be 560.3 kJ : 2BrF3(g) Br2(g) 3 F2(g) Based on this value and the standard enthalpies of formation for the other substances, the standard enthalpy of formation of BrF3(g) is kJ/mol. sample of solid platinum is heated with an electrical coil. If 31.9 Joules of energy are added to a 14.7 gram sample and the final temperature is 38.9oC, what is the initial temperature of the platinum
