first of all balanced equation is an equation in which the number of atoms of an element in the reactant is equal to the number of atoms of that same element in the product
so if you want to balance an equation
1. write the equation.
2. check if the eqn is not balance
3.add number to the element coefficient to make it balanced.
EXAMPLE
ZnO2+H2--Zn+H2O
this eqn is not balanced.
lets balance it, every element is balance except Oxygen(O) it has 2 in the reactant and 1 in the product in order to make it balance multiply 2 to H2O and multiply 2 to H2 to make the equation balanced.
ZnO2+2H2---Zn+2H2O *
