Calculate the pH and fraction of dissociation () for a 0.00345M solution of the acetic acid (CH3COOH, pKa=4.756) solution.

your parents i think this could be it

if the temperature drops and becomes cool

then the atmosphere can be freezing as the water vapor in the air is at maximum (100%) and can be severely cold

also can be snowing lightly as the moisture in the air will start to solidify

and btw this is not chemistry but

the enthalpy change that occurs in a system when matter is transformed by a given chemical reaction, when all reactants and products are in their standard states.
