Answer:
electrolysis of brine
Explanation:
Rock salt deposits are usually mined; occasionally water is pumped down, and brine which contain 25 percent of sodium chloride is found
so d brine is electrolyzed to produce chlorine
Chemical equation is the symbolic representation of chemical reactions.
Explanation
Chemical reactions are known as the reaction where two or more molecules or compounds react with each other leading to formation of product compounds along with either release or absorption of energy.
The symbolic representation of the processes occurring in a chemical reaction is termed as chemical equation.
The symbolic representation includes the reactants, products, external energy type and quantity of external energy and also about release of energy if occurs.
So the reactants are usually written in the left side of the chemical equation whereas on the right the products are written.
Both the sides are linked by a single headed arrow mark.
Some both the sides are linked by double heated arrow mark indicating the equilibrium chemical reaction.
Answer:
The formal charge on nitrogen in 
is +1.
Explanation:
The structure of is as follows.
(In attachment)
From the structure, Nitrogen has no non bonding electrons. Nitrogen has four bonds and each bond corresponds to 2 electrons. Hence, nitrogen have eight bonding electrons and five valence electrons.
![Formal\,charge\,on\,nitrogen = 5-[0+ \frac{8}{2}]= +1](https://tex.z-dn.net/?f=Formal%5C%2Ccharge%5C%2Con%5C%2Cnitrogen%20%3D%205-%5B0%2B%20%5Cfrac%7B8%7D%7B2%7D%5D%3D%20%2B1)
Therefore, The formal charge on nitrogen in is +1.
The answer is
a symmetrical molecule.
