Using H-H 432.0, Cl-Cl = 239.7, H-Cl = 428.0, determine the rH for the reaction:
H?H (g) + Cl?Cl(g) 2H?Cl (g)
2. If the rH of combustion of CH4 is -802kJ/mol. How many grams of water, which has a specific heat of 4.184 J/g-oC, can be heated from 20oC to 90oC by combustion of 2.00 mol of CH4?© BrainMass Inc. brainmass.com December 24, 2021, 4:56 pm ad1c9bdddf
