<u>Answer:</u> The equilibrium concentration of is 0.332 M
<u>Explanation:</u>
We are given:
Initial concentration of = 2.00 M
The given chemical equation follows:
<u>Initial:</u> 2.00
<u>At eqllm:</u> 2.00-2x x x
The expression of for above equation follows:
We are given:
Putting values in above expression, we get:
Neglecting the value of x = 1.25 because equilibrium concentration of the reactant will becomes negative, which is not possible
So, equilibrium concentration of
Hence, the equilibrium concentration of is 0.332 M
Answer:
The answer is B
Explanation:
3+ means there is 3 more protons than electrons.
So electron need 3 more (-ve) charge in order to have the same charge as proton to become neutral atom (no charge).
e + 3 = 8
e = 8 - 3
= 5
