1(a) Hess's Law states that the total enthalpy change in a chemical reaction is independent of the route taken from reactants to products, provided the initial and final conditions are the same.
Usefulness: It enables calculation of enthalpy changes that cannot be measured directly (e.g. ΔHf of C₂H₆) by combining known enthalpy changes of related reactions.
1(b)
Required: 2C(s) + 3H₂(g) → C₂H₆(g), ΔHf = ?
ΔHf = [2ΔH₁ + 3ΔH₂] − ΔH₃
= [2(−393.5) + 3(−285.8)] − (−1560.0)
= [−787.0 − 857.4] + 1560.0
= −1644.4 + 1560.0
ΔHf(C₂H₆) = −84.4 kJ/mol

i. Elasticity – the property of a material that enables it to return to its original shape and size after the deforming force is removed.

iii. Ductility – the ability of a material to be drawn or stretched into thin wires without breaking.
iv. Malleability – the ability of a material to be hammered or rolled into thin sheets without breaking.
