Chemical equation
A chemical equation is used to represent a chemical reaction. It includes all the reactants and products taking part in the reaction. An unbalanced chemical equation is the equation obtained by listing the reactants and products of the reaction. It is considered balanced when the number of atoms on the reactant side and the product side becomes equal.
Hit and Trial method
A chemical equation is balanced by adding coefficients to the reactants and products such that number of atoms becomes equal. This method is called mass balancing it involves a hit and trial method. Hydrogen and oxygen atoms are balanced last during this method. A balanced chemical equation gives relative amounts of reactants and products in the reaction. The coefficients in a balanced chemical equation are called stoichiometric coefficients. The states of the reactants and products are also mentioned in a balanced equation.
Preparation of Acetylene
Acetylene or Ethyne (C2H2) is prepared by the reaction of Calcium carbide (CaC2) with Water (H2O). The reaction is an example of hydrolysis reaction and the unbalanced chemical equation for the reaction is:
(Calcium (water) (Calcium (Acetylene)
carbide) hydroxide)
The chemical equation can be balanced by hit and trial method by adding coefficients such that the atoms are equal on both sides. Calcium carbide is a solid and Ethyne is produced as a gas in the reaction.
The balanced equation for the reaction is:
(Calcium (water) (Calcium (Acetylene)
carbide) hydroxide)
