Here are some examples of balanced chemical Equation. Any special reaction condition is mentioned on the top of the arrow like heat (∆) of light (hv) etc. Sometimes fractional coefficients are used to balance equation which then converted to an integer by multiplying the entire equation by a whole number. Beginning with most complex formula, so that the number of atoms of each element is the same on both sides. Solid substances are written as (s), liquid substances are written as (l) and gaseous substances are written as (g), Solutions are mainly expressed as (aq) means aqueous.Ī chemical equation is balanced by placing coefficients in front of chemical formulas one at a time. States of the reactant and product substances are written with parenthesis. The coefficients are written in front of the reactants and products and they tell how many molecules or moles of a substance react or are formed. Just like a cooking recipe, A chemical equation contains the starting materials on left side of an arrow and the products on the right. The bonded atoms are rearranged in a chemical reaction but the total mass remains same. Therefore, the total atoms present in a reaction before and after must be same. According to law of conservation of mass, matter of the universe is conserved and it can never be destroyed or created. Balancing of chemical equation is required because of law of conservation of mass and energy.
