6CO2 + 6H20 ---(sun's energy)--> 1C6H12O6 + 6O2
Carbon Dioxide + Water ---(sun's energy)--> Glucose + Oxygen
When a chemical reaction occurs, it can be described by an equation. This shows the chemicals that react (called the reactants) on the left-hand side, and the chemicals that they produce (called the products) on the right-hand side. The chemicals can be represented by their names or by their chemical symbols. Unlike mathematical equations, the two sides are separated by an arrow, that indicates that the reactants form the products and not the other way round. Any chemical change in substance whether combination, decomposition, displacement or arrangement of the molecules of the substance which involves the transformation of matter into a new substance is termed as chemical equation.
An unbalanced equation that uses names of the substances instead of chemical formulas is called a word equation. As a rule, metallic elements are named first and non-metallic next. The suffix of the latter is changed into "ide".

If you want to react say , hydrochloric acid with zinc, the word equation is : - Hydrochloric Acid and Zinc react to produce Zinc Chloride and Hydrogen . The chemical equation is 2HCl(aq) + Zn(s) = ZnCl2(aq) + H2(g) (aq) means aqueous solution (s) means solid (g) means gas.
In a chemical equation, each element has a symbol (in the periodic table in the elements). You use those symbols to create a chemical equation. For example, water is H2O. "H" represents Hydrogen, "O" represents Oxygen and the 2 means that there are two oxygen particles for each oxygen particle. Together, this creates one water molecule.

A chemical formula is the way a particular chemical (element or compound) is represented using the letters given in the Periodic Table. For example, the chemical formula of oxygen is O2 and the chemical formula of caron dioxide is CO2A word equation describes a chemical reactionusing the names of chemicals only. For instance, the word equation for respiration is:glucose + oxygen => carbon dioxide + waterA formula equation also describes a chemical reaction, but uses chemical formulae instead of names and is balanced. An example of this would be methane burning in oxygen:CH4 + 2O2 => CO2 + 2H2O

H2O is the molecule that is the source of oxygen from photosynthesis. It is important to note that the oxygen is a by-product of photosynthesis. Some chemical names for it includes hydrogen hydroxide and dihydrogen monoxide.

1.) Identify the names of the reactants and the product, and write a word equation. 2.) Write a formula equation by substituting correct formulas for the names of the reactants and the products. 3.) Balancing the formula equation according to the law of conservation of mass. 4.) Count atoms to be sure that the equation is balanced.

Most products are not sold by their actual chemical names. A very few, however, are known by their true chemical names or close variants. Metals are simply known by and sold under the name of the element (copper, lead, iron, etc.), while other products are known by their common molecular names like sodium bicarbonate (soda), lithium (medication), and helium (to fill balloons).
A word equation is where you describe a reaction using the chemicals by their names Eg. Hydrogen+Oxygen>Water A formula/symbol equation is where you use each chemical's formula (which is a group of the elements it consists of) Eg. H2+O2>H2O (you should use small letters for the numbers after the element)
a formula equation
It is called a subscript. For example: In the formula for water (H2O), 2 is the subscript indicating that there are 2 hydrogen atoms in the compound .
