How much heat is evolved when 6.688 moles of Cu(s) is burned in excess oxygen

  • Chemistry - , Wednesday, January 19, 2011 at 2:10pm

    Cu(s) + O2(g) ==> Cu2O(s)
    Look up the heat of formation of Cu2O. That will be the heat evolved (or absorbed) depending upon the sign of delta H. The number you look up is J/mol (or kJ/mol). Multiply that by 6.888.
