Answer:
-12 258 kJ
Step-by-step explanation:
Reaction 1: C₃H₈(g)+5O2(g) ⟶ 3CO₂(g)+ 4H₂O(g); ΔH₁ = - 2 043 kJ
Reaction 2: 6C₃H₈(g)+30O2(g) ⟶ 18CO₂(g)+ 24H₂O(g); ΔH₂ = -12 258 kJ
Reaction 2 is Reaction 1 multiplied by 6.
ΔH is an extensive property, so you must also <em>multiply ΔH by 6</em>.
Answer:
There are way in separating mixtures of chloride salts such as that of sodium chloride and ammonium chloride. It can be done by crystallization, filtration, and sublimation. The easiest method among the three is separation by sublimation.

Clouds are a source of Infrared Radiation. When cloud coverage increases, the infrared radiation also increases. So the clouds basically act as space heaters. This emits energy towards the ground, which is what makes cloudy nights warmer. While with clear sky’s all the heat from the day just escapes back into the atmosphere so the temperatures will be colder.
