Question

How to balance the chemical equations correctly?

Answer 1

TO BALANCE CHEMICAL EQUATION CORRECTLY
FIRST STEP - YOU HAD TO MAKE TWO COLUMNS IN WHICH COMPOUNDS OF PRODUCT AND REACTANT WERE WRITTEN.
SECOND STEP- THEN YOU SEE THE MOLECULES OF EACH COMPOUND  IN BOTH AND BALANCED IT .
                                      PLZ MARK IT BEST

Answer 2

chemical equation consists of reactants and products. reactantsare written on the left side  and products on the right side. no. of molecules of elements on the left side should be same as that on the right side for eg 2H2+O2---->2H2O                    NOof HYDROGEN ON THE LEFT SIDE=4,  NO. OF OXYGEN ON THE LEFT SIDE=2  NO. OF HYDROGEN ON THE RIGHT SIDE=4 ,AND  NO .OF OXYGEN ON RIGHT SIDE=4 SO THE EQUATION IS BALANCED
