1. For the following reaction:

2 SO2 (g) + O2 (g) → 2 SO3 (g) ΔHf SO3 (g) = −397.77 kJ/mol

a. Calculate the heat change for the reaction of 37.8 g sulfur dioxide in excess oxygen.

b. Will the temperature of the surroundings increase or decrease as a result of this reaction? Why?

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

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
