photosynthesis:
carbon dioxide + water + light = sugar and oxygen
6CO2+6H2O+light = C6H12O6+6O2)
a word equation, or a chemical equation
This representation is a chemical equation.
The shorter and easier way to show chemical reactions using symbols instead of words is called a chemical equation.
Writing a chemical reaction with symbols: Ex.: NaCl + AgNO3 = AgCl (s) + NaNO3 A mathematical (digital) system for the writing of chemical equations exist but it is rarely used.
The equation for water evaporation can be represented as: H2O (liquid) → H2O (gas) This shows the process where liquid water turns into water vapor through evaporation.
Chemical equations are representative for chemical reactions.

A chemical reaction is always written with the reactants (the things you mix together to do the reaction) on the left and the products (the stuff you get) on the right. In between is an arrow pointing right to indicate that the reactants react and become the products. Catalysts are sometimes listed above the arrow. And don't forget to balance the equation.
These arrows show the sense of a reaction.
Unbalanced equation is calles skeletal equation. The difference between these equations is that the skeleton equation doesnot show the no. of atoms and molecules in the equation whereas the balanced chemical equation shows. Also the balanced chemical equation shows that the products and the reactants are solid, liquid, gas or aqueous.
The equation for water evaporation can be represented as: H2O (liquid) → H2O (gas) This shows the process where liquid water turns into water vapor through evaporation.
The coefficient times the subscripts in a chemical formula show you the number of atoms of each element for each substance in the equation.
