You are given the initial concentrations of a reaction and you are asked to calculate the concentrations in equilibrium. In some cases you need an equilibrium constant, in other cases you don’t. When do you need it? When do you not need it?

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.

I'm sorry i cant you if you don't list the elements : (

(no3)⁻n has oxidation number x,o has oxidation number -2.(x*1 -2*3) charge of the nitrate ion, and we know that charge of the nitrate ion =-1.so,(x*1 -2*3) =-1x-6=-1x=+5answer a. +5.
