Question

Chemical equation for the reaction

Answer 1

reactants -> products

Answer 2

What is chemical equation of reaction?

Answer 3

you have a reaction where a substance "A" is going to interact with another substance "B" to produce a new compound "C"(other substance with different properties). This is your reaction explained with word.
An everyday example is when you turn on your gas stove, the gas is going to react with oxygen from the air and produce the flame with heat and also the gas is going to be break it into water molecules and carbon dioxide that will escape as gases and mix with the air.
According to wikipedia:
A chemical equation is the symbolic representation of a chemical reaction wherein the reactant entities are given on the left-hand side and the product entities on the right-hand side.[1] The coefficients next to the symbols and formulae of entities are the absolute values of the stoichiometric numbers. The first chemical equation was diagrammed by Jean Beguin in 1615.[2]

we can put this words in a chemical equation, we put the substance before the reaction in the left side of the equation and then an arrow indicate the reaction is occurring after the arrow we put the substance that form after the reaction. In the first example with the letters we can said

A + B -> C

we can be even more specific about the reaction and said how much of each component will react and how much we will obtain after the reaction and include this coefficients in the chemical equation

2A + 3B -> 2C

all the substance that are at the LEFT of the arrow are called the REACTANTS of the reaction and the ones at the RIGHT are the PRODUCTS of the reaction
