(a) what is the meaning of the derivative s '(t)? s '(t) is the rate at which oxygen solubility changes with respect to the oxygen solubility. s '(t) is the rate at which temperature changes with respect to the oxygen solubility. s '(t) is the rate at which temperature changes with respect to the temperature. s '(t) is the current level of oxygen solubility for a given temperature. s '(t) is the rate at which oxygen solubility changes with respect to the water temperature.

S '(T) is the rate at which oxygen solubility changes with respect to the water temperature.

Explanation:

Solubility (S) is the maximum amount of a solute that may be dissolved in a fixed mass of solvent. It usually depends on temperature (T), which we can express as S = S(T). Thus, the derivative S '(T) is the rate at which oxygen (solute) solubility changes with respect to the water (solvent) temperature.

the answer is either b or c

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
