it is tedious and takes a long time
it is quite difficultto balance a chemical equation
The main methods for balancing a chemical equation are inspection, trial and error, and algebraic methods. Inspection involves visually balancing the equation by adjusting the coefficients of the compounds. Trial and error involves systematically changing coefficients until the equation is balanced. Algebraic methods involve setting up and solving a system of linear equations to determine the coefficients.
The easiest way to balance a chemical equation is by using the trial-and-error method. Start by balancing the most complex or uncommon elements first, then adjust the coefficients until the number of atoms on both sides of the equation is equal.
PARTIAL EQUATION METHOD:----- When equations contain many reactants and products they cannot be balanced by the hit and trial method. They are then balanced by the partial equation method. In this method the overall reaction is assumed to take place through two or more simpler reactions, which can be represented by partial equations. The steps involved are: Steps and problem * The given chemical equation is split into two or more partial equations. * Each partial equation is separately balanced by the hit and trial method. * These balanced partial equations are multiplied with suitable coefficients in order to exactly cancel out those common substances which do not appear in the overall chemical equations. * The balanced partial equations so obtained, are added to arrive at the balanced chemical equation. PROBLEM Balance the equation, NaOH + Cl2---------------------------------> NaCl + NaClO3 + H2O by partial equation method. SOLUTION The given skeleton equation can be split into two partial equations. Partial eq.1 NaOH + Cl2---------------------------------> NaCl + NaClO + H2O Partial eq.2 NaOCl ------------------------------> NaCl + NaClO3 The two partial equations are balanced by hit and trial method. Balanced partial eq.1 2NaOH + Cl2---------------------------------> NaCl + NaClO + H2O Balanced partial eq.2 3NaOCl ---------------------------------> 2NaCl + NaClO3 NaClO does not appear in the overall equation and so to cancel it, the partial balanced equation 1 is multiplied by 3 and the two equations are added to get the overall balanced equation. 2 NaOH + Cl2---------------------------------> NaCl + NaClO + H2O * 3 3NaOCl ---------------------------------> 2NaCl + NaClO3 FINALLY 6NaOH + 3 Cl2---------------------------------> 5NaCl + NaClO3 + 3H2O
Balancing equations is the act of adding coefficients (the large font number in from of the formulae) to the reactants (what will react) and the products (what is formed by the reaction) so that no atoms are spontaneously created or destroyed in the reaction; what goes in has to equal what comes out. If you'd ever like to get into chemistry, you'll need to know how to balance chemical equations; it's a very basic skill used throughout almost all of chemistry.
I don't remember all of the mathematical names, but I do remember that you need to balance equations so that both sides will be equal. These are very simple examples but they will show you that balanced equations are equivalentto being equal.Such as: (2+2)=4=(3+1) Both sides equal '4'.Differing equations on opposite sides of the equal sign demonstrate that are differing ways to express a certain figure.Or: (2+6)-(3x1)=5=(2x2)+(4-3) Here both sides equal '5'.(8) - (3) =5= (4) + (1)Hope this helps.

There are many equations for which there is no method for obtaining an exact solution. In such circumstances, an efficient trial and error method may be the only way.

Balancing an equation is done by adjusting the coefficients of the chemical formulas to ensure that the number of each type of atom is the same on both sides of the equation. This is typically achieved by trial and error, starting with the most complex compounds and balancing the elements one at a time.
