Answer: Weak acids are poor conductors of electricity.
Explanation:
Weak acids are defined as the acids which dissociate weakly or partially when dissolved in water (polar solvent).
For example, 
Due to less dissociation there will be less number of ions present in a solution of weak acid. As a result, a weak acid will be poor conductor of electricity.
As electricity is the flow of ions.
Thus, we can conclude that weak acids are poor conductors of electricity.

Answer:
If temperature stays the same, the amount of carbon dioxide dissolved in the ocean would increase.
Explanation:
The carbon dioxide in the air (
) and the carbon dioxide dissolved in the ocean (
) are in a solution equilibrium:
.
Assume that the concentration of carbon dioxide in the air (
) increased while temperature stayed the same.
By Le Ch
atelier's Principle, the solution equilibrium
would shift to offset this increase in
concentration. Specifically, this equilibrium would reduce the amont of
in the system by converting more atmospheric
to
dissolved in the ocean. Therefore, the concentration of
dissolved in the ocean would increase.
