A buffer solution is 0.24 M NH3 and 0.20 M NH4Cl
A. Calculate the pH of the 0.20 M NH3/0.16 M NH4Cl buffer.
B. What is the pH of the buffer after the addition of 10.0 mL of 0.10 M HCl to 62.5 mL of the buffer?

air quality

poor drinking water

and heavy polution

can lead to poor health

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
