Answer

Africa

Explanation:

Burning fossil fuels and deforestation is disturbingly heightened in Africa with almost no viable measure taking to control it's effect. No effective programs are presently in place to control excessive tree falling used for herbs, firewood, charcoal business and a whole lot. Below standard carbon rating PMS are in high circulation with fumes, carbon monoxide is full abundance in the atmosphere. Presently, all these unchecked activities have resulted into unexplainable excessive increase in temperatures, breeding neck twisting diseases, severe skin infections, dehydration and increase diabetes. Drought has eaten up landlocked cities in Nigeria and Central Africa. Infact farmers have lost count of the usual natural cycle of rainfall and the beginning of each farming season due to this essential evil of climate change

Which pair has identical electron configurations?

Thepotemich [5.8K]

Identical electron configurations : K⁺ and Cl⁻

<h3>Further explanation </h3>

In an atom, there are levels of energy in the shell and sub-shell

This energy level is expressed in the form of electron configurations.

Charging electrons in the sub-shell uses the following sequence:

S²⁻ and CI

S²⁻ : [Ne] 3s²3p⁶

Cl : [Ne] 3s²3p⁵

K⁺ and CI⁻

K⁺ : 1s² 2s² 2p⁶ 3s² 3p⁶

Cl⁻ : 1s² 2s² 2p⁶ 3s²3p⁶

S and Ar

S :[Ne] 3s²3p⁴

Ar : [Ne] 3s²3p⁶

Cl⁻ and K

Cl⁻ : 1s² 2s² 2p⁶ 3s²3p⁶

K : 1s² 2s² 2p⁶ 3s² 3p⁶4s¹

<u>Answer:</u> The expression for equilibrium constant is $K_{eq}=\frac{[HOCl]^2}{[H_2O][Cl_2]^2}$

<u>Explanation:</u>

Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as $K_{eq}$
