SOLVED: Predict ΔH for this reaction:C2H4(g) H2O(l) -> C2H5OH(l)using the enthalpy changes of the following reactions:C2H4(g) 3O2(g) -> 2CO2(g) 2H2O(l); ΔH = -1411.1 kJ/mol-rxnC2H5OH(l) 3O2(g) -> 2CO2(g) 3H2O(l); ΔH = -1367.5 kJ/mol-rxnReport your answer with units of kJ/mol-rxn. If your number is negative, include the negative symbol. If your number is positive, do not include the positive symbol.

SOLVED: Calculate ΔH and ΔS when two copper blocks, each of mass 10.0 kg, one at 100°C and the other at 0°C, are placed in contact in an isolated container. The specific heat capacity of copper is 0.385 J/g K and may be assumed constant over the temperature range involved.
