What is the net ionic equation for the reaction of solid iron with aqueous copper sulfate?

The reaction of solid iron with aqueous copper sulfate is an example of a single displacement type of reaction which exchanges only the cations of the element and the compound. In this case, the equation is 

Fe (s) + CuSO4 (aq) = FeSO4 + Cu (s) 

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.
