After preparing a dilute sodium hydroxide solution in a volumetric flask you notice that the meniscus of the solution is above the 100 ml mark on the flask neck. What should you do?

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.

Heating it up with cause a quicker reaction time

Well you can immediately rule out a and d because if a metal were to lose or gain protons, then it would become a different element all together. the answer here is b because the positive symbol with a number refers to how many electrons the metal can give away to become stable.
