Any 1 know These Chemicals??

A) 1 & 2 only

Explanation:

Seeing that the chemicals present are in question one I take it you are asking about that question.

Decreasing the concentration causes a decrease in reaction process and also the total amount of product you would get out of the given reaction

Decreasing the temperature causes the molecules in this reaction to become less excited or reactive, thus causing the reaction to slow down

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
