The correct answer is B. 
Explanation
The question provides us with information about the concentration of ![[OH^{-} ]](https://tex.z-dn.net/?f=%5BOH%5E%7B-%7D%20%5D)
and we are supposed to use this information to find the ![[H^{+} ]](https://tex.z-dn.net/?f=%5BH%5E%7B%2B%7D%20%5D)
concentration. The pH of a solution gives us information about
If we the reaction is in equilibrium and with standard conditions of 25°C, then pH is given by the formula
.
Once we find the pH we use the relationship ![pH= -log[H^{+} ]](https://tex.z-dn.net/?f=pH%3D%20-log%5BH%5E%7B%2B%7D%20%5D)
, then the ,is given by
![pH = -log[H^{+} ]\\\implies [H^{+} ]= 10^{-pH} = 10^{-5.8}= 1.58 \times 10^{-6}](https://tex.z-dn.net/?f=pH%20%3D%20-log%5BH%5E%7B%2B%7D%20%5D%5C%5C%5Cimplies%20%5BH%5E%7B%2B%7D%20%5D%3D%2010%5E%7B-pH%7D%20%3D%2010%5E%7B-5.8%7D%3D%201.58%20%5Ctimes%2010%5E%7B-6%7D)
To perform nuclear fusion reactions, the following requirements must be present: Get a very high temperature to separate the electron from the nucleus, approaching this another beating electrostatic repulsion forces. The gaseous mass consisting in the electrons and free atoms is called highly ionised plasma.
So, it’s chemical plasma.

Answer:
Tectonic plates slides against each other. Though when two plates run into each other one gets pushed underneath while the other plate gets pushed up. This is how mountains and volcanoes are formed.

Explanation:
During the formation of BeCl2, the beryllium atom bonds with two chlorine atoms via single covalent bonds. The number of electron pairs around the central atom will be two. No lone pair is found in the molecule. If we analyse this information then we can conclude that BeCl2 has sp hybridization.
