Question

step of writing a chemical equation and its specification also???...

Answer 1

Hey mate
Here is ur answer

The reactants is written on the left side ,products is written on the right sideand seperated by an arrow
Example
C + O2-------> CO2

Answer 2

Certain rules have to be followed in writing a chemical equation
1- The reactant taking part in the reaction are written in the terms of their symbol or molecular formulae on the left hand side of the equation.
2-A sign of plus(+) is added between the formulae of the reactant
3-The products of reaction are written in terms of their symbols or molecular formulae on the right-hand side of the equation.
4-A sign of plus (+) is added between the formulae of the products.
5-In between the reactants and the products an arrow sign(→) is marked to show which way the reaction is occurring.

Like this
A+B --------->C+D

The specification of chemical reaction is the alternative reaction paths leading to a desired chemical reaction.
