What do you understand by a balanced chemical equation? Explain with the help of an example.
Answers
Answer:
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.
for example :- (1.) C5H12 + O2 ---> CO2 + H2O
There are five carbons on the left but only one on the right, and on each side the carbon is in a single chemical species. Put a 5 in front of the CO2 on the right hand side.
C5H12 + O2 ---> 5CO2 + H2O
There are twelve hydrogens on the left but only two on the right hand side, and hydrogen is in a single species on each side. Put a 6 in front of the H2O on the right hand side.
C5H12 + O2 ---> 5CO2 + 6H2O
Finally, there are only two oxygens on the left hand side but 16 of them on the right hand side. So put a 8 in front of the O2 on the left hand side.
C5H12 + 8O2 ---> 5CO2 + 6H2O
It's now a balanced chemical equation.
(2.) Zn + HCl ---> ZnCl2 + H2
There are two chlorines on the right but only one on the left, and the chlorine is in a single chemical species on each side . Put a 2 in front of the HCl on the left hand side.
Zn + 2HCl ---> ZnCl2 + H2
the equation is now balanced, with one Zn on each side, two hydrogens on each side and two chlorines on each side.
