Which of the following can form both high- and low-spin octahedral complexes?
a. zn²⁺b. cr²⁺ c. cu⁺d. cr³⁺
e. all of the above can form either high- or low-spin complexes.

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.

1= c 2= a or d3 = idk sorry 4= c5= c
