Answer:
c) CH₃Cl
Explanation:
Due the relative abundance of chlorine and bromine. It is possible to determine which of the halogens is present in a mass spectrum of a organic compound:
The Cl-35, Cl-37 have a relative abundance of 75/25; Br-79 and Br-81 of 50/50.
For that reason, if a compound has a M/M+2 ratio of 75:25 you can be sure the compound has 1 Cl in its structure. Thus, the only possible structure is:

c) CH₃Cl</h3>
Answer:
hot air rises because gases expand as they heat up.When air heats up and expands,its density also increases.The warmer,less dense air effectively floats on top of the colder, dense air below it. This creates a buoyant force that causes warmer air to rise.
cold air sinks because it is heavier as its more dense ( because of closely packed molecules) soits harder for them to move and they absorb less energy. Also, gravity pulls on it more strongly.
Hope it helps :)
Because they are the means by which energy needed for photosynthesis is transported into the plant in form of light ernegy
I believe that it is B chemicals containing carbon
HC₂H₃O₂ , equilibrium can be represented as:
HC₂H₃O₂ + H₂O--------->CH₃COO⁻ + H₃O⁺
HC₂H₃O₂, that is acetic acid dissociate in water that is H₂O and formed acetate anion that is CH₃COO⁻ and hydronium ions that is H₃O⁺.
Its equiibrium constant can be represented as:
Ka=\frac{[CH_{3}COO^{-1}]\times [H_{3}O^{+1}]}{CH_{3}COOH}
While NaC₂H₃O₂ can be dissociate as:
NaC₂H₃O₂------>CH₃COO⁻ + Na⁺
Sodium acetate that is NaC₂H₃O₂, dissociates as forming acetate anion and sodium cation.
