Answer: The correct option is A ( Break the crackers into pieces.)
Explanation:
The rate of reaction between two substances can be affected by the following factors:
--> surface area of reacting substances
--> concentration
--> reaction mechanism
--> temperature
--> the presence of a catalyst and
--> pressure ( if gaseous)
Reagents in solution tend to react faster than reagents in solid form. This is because molecules are freer to move about and collide more effectively in solutions. For example, a lump of zinc will not react as fast as powdered zinc with dilute hydrochloric acid to produce hydrogen. This is the same with the reaction between the crackers and soup. To increase the reaction of the substances, the crackers needs to be broken into pieces(thus,increased surface area)

Answer:
It’s either B or C:
В. have the same atom arrangement as the reactants.
С. have different properties than the reactants.

Sorry, I don’t know a lot about this topic :(
<span>A population of the frogs that do not receive the UV radiation would work as a good control group. In this case, since the impact of the radiation is the variable under study, a group that receives no radiation, and thereby should not exhibit a change, would be a control group that could be compared against the frogs that do receive the radiation.</span>
