Answer:
ΔH = - 44.0kJ
Explanation:
H2O(l)→H2O(g), ΔH =44.0kJ
In the reaction above, liquid water changes to gaseous water. This occurs through a process known as boiling. This process requires heat, hence the ΔH is positive.
If he reaction is reversed, we have;
H2O(g)→H2O(l)
In this reaction, gaseous water changes to liquid water. This process is known as condensation. The water vapor loses heat in this reaction. Hence ΔH would be negative but still have the same value.

Answer:
∆H = -763kJ
Explanation:
Using Hess's law we can determine the ΔH of a reaction from the sum of similar reactions. Using the reactions:
<em>(1) </em>2PCl3(l) → 2P(s) + 3Cl2(g) ∆H = -640 kJ
<em>(2) </em>2P(s) + 5Cl2(g) → 2PCl5(s) ∆H = -886 kJ
The sum of (1)/2 + (2)/2 gives:
(1) / 2 = PCl3(l) → P(s) + 3/2Cl2(g) ∆H = -640 kJ/2 = -320kJ
(2) / 2 = P(s) + 5/2Cl2(g) → PCl5(s) ∆H = -886 kJ/2 = -443kJ
PCl3(l) + Cl2(g) → PCl5(s) ∆H = -320kJ - 443kJ =
<h3>∆H = -763kJ
