Concentrated (stock) hydrochloric acid (12 M) solution is purchased from a chemical supply company. You must make up 500. mL of 0.200 M HCl solution for your lab. How many mL of the stock HCl will you need?

i think it's c. i'm not sure but i think so.

b) nuclear ive learned that in a pedtrodic table

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
