Balence the chemical reaction
KMnO₄ + H₂So₄ ⇌ MnSo₄ + k₂So₄+ H₂O + O₂
To balance this chemical equation let us follow steps.So it is easy to understand.
✪ Identify the number of Potassium(K) and Magnesium(Mn) on the either side of the reaction as they are main reacting elements
✪ 1 K and 1 Mn are on the L.H.S while 1 Mn and 2 K are on the R.H.S
✪ So if we add 2 on L.H.S to KMno₄ it is not balanced as oxygen atoms are differing
✪ So now we need to add 4 to KMno₄ then it is correctly matching as 4 K ions on both left and right hand side as well as 4 Mn ions on both left and right hand side
✪ Now coming to H₂So₄ totally 9 o atoms on R.H.S while 20 o atoms of L.H.S
✪ Let us add 6 to H₂So₄ then it became balanced completely on L.H.S
✪ Coming to R.H.S we need to add 2 to K₂So₄
✪ 4 to MnSo₄ , 6 to H₂O and 5 to O₂
Then complete balanced equation of this question is given as
4KMnO₄ + 6H₂So₄ ⇌ 4MnSo₄ + 2k₂So₄+ 6H₂O + 5O₂
is the required balanced equation of the given question
How to Provide balanced equation to any given chemical reactions
Follow these common steps
Step 1: The Unbalanced Chemical Equation
Write the unbalanced chemical equation given in the question
Eg: Al + O₂ -----> Al₂O₃
Step 2: Make a List
Make the list of main reacting elements in the reacting equation
Eg: Al + O₂ -----> Al₂O₃
L.H.S | R.H.S
Al: Al:
O: O:
Step 3: Identifying the Atoms in Each Element
Identify the number of atoms given in each element
Eg: Al + O₂ -----> Al₂O₃
L.H.S | R.H.S
Al: 1 Al: 2
O: 2 O: 3
Step 4: Multiplying the Number of Atoms
Multiply the number of atoms on both sides to make same no of atoms
Eg: Al + O₂ -----> Al₂O₃
L.H.S | R.H.S
Al: 1.2 = 2 Al: 2
O: 2.3 = 6 O: 3.2 = 6
Step 5: Placing Coefficients in Front of Molecules
Write the coefficients of multiplied values in front of molecules.
Eg: 2Al +3 O₂ -----> 2Al₂O₃
Step 6: Check Equation
Let us check the balanced chemical equation
Eg: 2Al +3 O₂ -----> 2Al₂O₃
L.H.S | R.H.S
Al: 4 Al: 4
O: 6 O: 6
Hence the reaction is easily balanced
