The best answer is "<span>High temperatures increase the activation energy of the reaction."
The Haber process is an exothermic reaction at room temperature. This means that the reaction actually favors the reverse reaction, especially when the temperature is increased. So why increase the reaction temperature?
The reason for this is that nitrogen is a very stable element. Therefore, more energy is needed to overcome the slow rate of reaction. So the reaction temperature must be low enough to favor a forward reaction, but high enough to speed up the reaction.</span>
Answer:
Three Na atom(s) each lose one electron, forming three Na+ ions. One N atom gains three electrons, forming a N^-3 ion. The ions attract, forming Na3N
Explanation:
Three Na atom(s) each lose one electron, forming three Na+ ions. One N atom gains three electrons, forming a N^-3 ion. The ions attract, forming Na3N.
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Na₃N is ionic compound. The electronegativity of is 3.04 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the nitrogen. Sodium becomes positive and nitrogen becomes negative ion.
One nitrogen atom required three electrons to complete the octet while sodium have one valance electron that's why three sodium atoms combine with one nitrogen atom.
Answer: The hydrogen ion concentration in molarity is 0.013
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pOH is calculated by taking negative logarithm of hydroxide ion concentration and pH is calculated by taking negative logarithm of hydrogen ion concentration
Putting in the values:
![pOH=-\log[7.609\times 10^{-13}]](https://tex.z-dn.net/?f=pOH%3D-%5Clog%5B7.609%5Ctimes%2010%5E%7B-13%7D%5D)

Now , 

![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
![[H^+]=0.013M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D0.013M)
The hydrogen ion concentration in molarity is 0.013
Yes, this experiment is also an example of a chemical reaction. The original substance, hydrogen, disappeared, and a new substance, water, was formed.
