Answer:
See explanation
Explanation:
The reaction of a benzyl bromide with a nucleophile may proceed by SN1 or SN2 mechanism depending on the nature of the solvent used.
Since SN1 reaction involves the formation of a carbocation, it usually predominates in the presence of a poor nucleophiles and protic solvents. Hence when methanol is used as solvent and a poor nucleophile is used, SN1 mechanism predominates.
However, when acetone which is an aprotic solvent is used in the presence of a good nucleophile, SN2 reaction mechanism predominates.

A compound is formed due to the chemical combination or chemical reaction between two or more elements. The elements forming a compound cannot be separated by physical means. The properties of the compound is different from the properties of the elements forming it.
Based on this, the answer would be:
They are different.
I choose the letter c witch is density I believe that it’s useful for determining identifying relationships between substances
Answer:
Explanation:
Rate laws are mathematical expressions which define the relationship that exists between the rate of a chemical reaction and the concentration of the reacting components. Rate laws take the following form:
![rate = k [A]^{x} [B]^{y} [C]^{z}](https://tex.z-dn.net/?f=rate%20%3D%20k%20%5BA%5D%5E%7Bx%7D%20%5BB%5D%5E%7By%7D%20%5BC%5D%5E%7Bz%7D)
...
where k = rate constant
[A], [C] and [C] represent the molar concentrations of the reactants
k, x, y, and z are determined experimentally by observing how the rate of reaction changes with the concentrations of the reactants.
If x=1, the reaction is first order for [A]. Also, if y=2, the reaction is second order for [B] and so on...
The overall order of the reaction is the sum of the orders with respect to each reactant. Therefore, the overall order of the reaction is x+y+z.
