Calculate Kc for the reaction: 2 HI(g) ⇄ H2(g) + I2(g) given that the concentrations of each species at equilibrium are as follo

Paul [167]

<u>Answer:</u> The value of $K_c$ for the given reaction is 0.224

<u>Explanation:</u>

For the given chemical equation:

$2HI(g)\rightleftharpoons H_2(g)+I_2(g)$

The expression of $K_c$ for given equation follows:

$K_c=\frac{[H_2][I_2]}{[HI]^2}$

We are given:

$[HI]_{eq}=0.85M$

$[H_2]_{eq}=0.27M$

$[I_2]_{eq}=0.60M$

Putting values in above expression, we get:

$K_c=\frac{0.27\times 0.60}{(0.85)^2}=0.224$

Hence, the value of $K_c$ for the given reaction is 0.224

What is the charge of an aluminum ion? (2 points) Select one: a. 2+ b. 3+ c. 2- d. 3-

choli [55]

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:

$Al\rightarrow Al^+^3+3e^-$

So, the right choice is b. 3+.
