Consider the one step reaction aA Arrow in between) B with the following rate law Rate=k(A)^x. When the initial concentration of A is increased from 0.35 mol\L to 0.7 mol\L, the initial rate increases from 1.6 mol\(L. s) to 3.2 mol\(L. s). What is the order of the reaction with respect to A? What is the overall order of the reaction? PLEASE HELP. It is due tomorrow and I can't figure it out. please SHOW YOUR WORK so I can understand how its done. I will mark brainiest.

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.

a:

by the combination of an unlimited number of elements

c (diamond),

sio2 (quartz)

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
