For the following reaction, increasing the pressure will cause the equilibrium to . 2SO2 (g) + O2 (g)_ 2 SO3 (g) +heat
A) remain unchanged, but the reaction mixture will getcooler
B) shift to the right, towards products
C) shift to the left, towards reactants
D) remain unchanged, but the reaction mixture will getwarmer
E) Pressure has no effect on equilibrium.

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

this is chemical change (chemical reaction), because two new substances are formed (metalig liquid and gas), the atoms are rearranged and the reaction is followed by an energy change.

this is example of chemical decomposition.

chemical decomposition (analysis) is the separation of a single chemical compound into its two or more elemental parts or to simpler compounds.  

chemical decomposition is opposite of chemical synthesis.

you gotta add the following molecules so we can give u an answer
