The heat absorbed when 1 mol of CS₂(g) forms from its elements at these conditions is 117.4 kJ.
Given,
Number of moles CS₂ = 1 mol
Temperature = 25° = 273 +25 = 298 Kelvin
Heat absorbed = 89.7 kJ
It takes 27.7 kJ to vaporize 1 mol of the liquid
Calculate the heat absorbed:
C(s) + 2S(s) → CS₂(l) ΔH = 89.7 kJ (positive since heat is absorbed)
CS₂(l) → CS₂g) ΔH = 27.7 kJ (positive since heat is absorbed)
Prior to summing, the equations should be balanced; however, because they are balanced already, there is nothing further we need to do.
C(s) + 2S(s)---> CS₂ (g)
ΔH = 89.7 + 27.7 = 117.4 kJ
Hence, the heat absorbed is 117.4 kJ.

As known, nitrogen could form 3 bonds based on octet rule, because it has 5 valence electrons. That means it needs 3
For example, a method that has been used to regulate or control global warming is planting trees. The pros of planting trees is they serve as an absorber of carbon dioxide which helps the ozone layer get protected by the oxygen trees produce and they also regulate the temperature in the atmosphere although the cons are these trees can also catch fire eaaily due to the rising temperature in the atmosphere which can make them less effective in regulating the warming of the globe.
