Use the information provided to determine ΔH°rxn for the following reaction: ΔH°f (kJ/mol) CH4(g) + 3 Cl2(g) → CHCl3(l) + 3 HCl(g) ΔH°rxn = ? CH4(g) -75 CHCl3(l) -134 HCl(g) -92

b. is the answer hoped i        

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
