Reactant p contains 50 j of energy, and reactant q contains 35.3 j of energy. the reactants combine to form product pq, which contains 104 j of energy. what is the energy transformation?

The chemical reaction based on the given above can be written as,
                       P + Q --> PQ
The energy in the left side of the equation will sum up to 85.3 J. That is the sum of the energy of P and Q. The energy in the right side of the equation is 104 J and is 18.7J more than that of the left side. This means that 18.7J of heat was absorbed during the process. 

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.
