Predict the pH of a 0.0050 M solution of a weak, polyprotic acid. Ka1= 4.3 x 10^-7
Ka2= 5.6 x 10^-11

since electrons are negative the answer is neagtaive

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
