The chemical symbol for nitrogen is N and it used so that compounds can be given a chemical formula such as NH3 and can be represented in chemical equations for the ease of identifying what elements are in what compounds.
(aq)
THE PLUS SIGN (+)an example is: sodium + oxygen --> sodium oxideNa2 + O --> Na2O
formulas
Coefficients are used to balance chemical equations. These numbers are placed in front of the chemical formulas to ensure that the number of atoms on both sides of the equation are equal.

So it is wrong equation .Symbols are very important
The chemical symbol of silver is Ag: chemical symbols are used in chemical formulae and equations.
The symbol on the periodic table means the abrevitation of the chemical element. For example, the chemical element symbol Pm stands for Promethium.
Each chemical element has a different chemical symbol formed from one or two letters: H for hydrogen, U for uranium, Cl for chlorine, Ar for argon, etc. Symbols are used for simplicity in writing equations, etc. The chemical symbol can be considered as a code.
The symbol for a substance that is soluble is (aq) which means aqueous or in aqueous solution.
(aq)
THE PLUS SIGN (+)an example is: sodium + oxygen --> sodium oxideNa2 + O --> Na2O
The symbol used to represent the electric field in equations is ( \vec{E} ).
Delta as a mathematical symbol usually means "change". It's usually used the same way in physics and chemistry, though it's sometimes used in chemical equations to represent heat.
A three-letter chemical symbol represents an element in the periodic table. Each element is assigned a unique symbol comprised of one to three letters. These symbols are used in chemical formulas and equations to represent specific elements.
