1 kg block of ice at 0^oC is placed into a perfectly insulated, sealed container that has 2 kg of water also at 0^oC. The water and ice completely fill the container, but the container is flexible. After some time, one can expect that

For the reaction of one mole of Zn dust with one mole of H₂SO₄ in a bomb calorimeter, ∆U and w correspond to

The enthalpy of hydrogenation of cyclohexene is -119.5 kJ/mol. If resonance energy of benzene is -150.4 kJ/mol, its enthalpy of hydrogenation would be

If the standard state of iodine and chlorine is I₂(s) and Cl₂(g) respectively, then what is the value of standard enthalpy of formation of ICl(g). You are given the following information:

Cl₂(g) → 2Cl(g); ∆H = 242.3 kJ/mol
I₂(g) → 2I(g); ∆H = 151.0 kJ/mol
ICl(g) → I(g) + Cl(g); 211.3 kJ/mol
I₂(s) → I₂(g); 62.76 kJ/mol

If the enthalpies of formation of Al₂O₃ and Cr₂O₃ are -1596 kJ and -1134 kJ, then what is the value of ∆H for the following reaction?

2Al + Cr₂O₃ → 2Cr + Al₂O₃
