The rate determining step for
the reactivity for the solvolysis of 2-chloro-norbornane depends only on the decomposition of a single molecular species which is
the 2-chloro-norbornane itself. For unimolecular reactions, the mechanism pathway being followed
is that of an SN1 mechanism.
Answer:

The question is incomplete, the complete question is:
A chemist prepares a solution of vanadium (III) chloride (VCl3) by measuring out 0.40g of VCl3 into a 50.mL volumetric flask and filling to the mark with distilled water. Calculate the molarity of Cl− anions in the chemist's solution. Be sure your answer is rounded to the correct number of significant digits.
Answer:
0.153M of anions
Explanation:
First we calculate the concentration of the solution. From m/M= CV
m=given mass, M= molar mass, C =concentration of solution, V= volume of solution
Molar mass of compound= 51 + 3(35.5)= 157.5gmol-1
0.4g/157.5gmol-1= C×50/1000
C= 2.54×10-3/0.05= 0.051M
But 1 mole of VCl3 contains 3 moles of anions
Therefore, 0.051M will contain 3×0.051M of anions= 0.153M of anions
Krypton is in group 18, and so it has 8 valence electrons. B is the answer
12: B, since it said the temperature is below 3,500
