HELPQuestion 1 of 32 How would the equilibrium of the reaction below be affected if the
temperature decreased?
0,(9) +250 (9)
2250 (9)+ 200 kj
A. Less O2, SO2, and SO3 would be produced.
B. More SO3 would be produced.
C. More O2 and SO2 would be produced.
D. More O2, SO2, and SO3 would be produced.

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

e

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
