<u>Answer:</u> The value of
for the given reaction is 0.224
<u>Explanation:</u>
For the given chemical equation:

The expression of
for given equation follows:
![K_c=\frac{[H_2][I_2]}{[HI]^2}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BH_2%5D%5BI_2%5D%7D%7B%5BHI%5D%5E2%7D)
We are given:
![[HI]_{eq}=0.85M](https://tex.z-dn.net/?f=%5BHI%5D_%7Beq%7D%3D0.85M)
![[H_2]_{eq}=0.27M](https://tex.z-dn.net/?f=%5BH_2%5D_%7Beq%7D%3D0.27M)
![[I_2]_{eq}=0.60M](https://tex.z-dn.net/?f=%5BI_2%5D_%7Beq%7D%3D0.60M)
Putting values in above expression, we get:

Hence, the value of
for the given reaction is 0.224

Answer:
-Grignard reagents are strong bases (third choice)
-Grignard reagents are strong nucleophiles ( second choice)
Answer:- b. +3
Explanations:- Charge of a metal ion is equal to the number of valence electrons it has as it loses these electrons to have its nearest noble gas like electron configuration.
Al has 3 valence electrons and being a metal it loses all of these and so the charge of Al ion is +3. It could be shown as:

So, the right choice is b. 3+.
