6 0

Electron configuration

an element A has 3 shells and has 3 valence electrons

so electron configuration of A: 1s², 2s², 2p⁶, 3s², 3p¹

will tend to lose 3 electron to form a cation: A³⁺

a. Nitrate of A

A(NO₃)₃

b. Chloride of A

ACl₃

c. Oxide of A

A₂O₃

Consider the chemical equation in equilibrium. A(g) 2B(g) Double headed arrow. C(g) D(g) heat What will happen to the equilibriu
Mazyrski [523]

If the temperature is increased then reaction will shift to the left because heat is absorbed.

<h3>What is equilibrium state?</h3>

Equilibrium of any reaction is that state in which concentration of reactant and concentration of product will be constant.

Given chemical reaction is:

A(g) + 2B(g) ⇄ C(g) + D(g)

From the equilibrium state reaction will move only that side which will contribute to maintain the stable state. In the forward reaction heat is released as mention in the question. So, when the temperature of reaction is increased then it shifts towards the left side by absorbing the heat and maintain the stability.

Hence, option (2) is correct, i.e. It will shift to the left because heat is absorbed.
