Question

how to balance any chemical equations?​

Answer 1

Explanation:

Write down your given equation. For this example, you will use: ...

Write down the number of atoms per element. ...

Save hydrogen and oxygen for last, as they are often on both sides. ...

Start with single elements. ...

Use a coefficient to balance the single carbon atom. ...

Balance the hydrogen atoms next. ...

Balance the oxygen atoms.

Answer 2

In balancing a chemical equation we have to make the reactants and products side equal in atoms of each element. Let us take a example:-

H₂ + O₂ ------> H₂O

In this reaction there is 2 atoms of hydrogen in reactant side and 2 atoms of hydrogen i product side.

But, there is 2 atom of oxygen in reactant side whereas 1 atom in product side.

In order to make them equal we will multiply with 2 in product side.

H₂ + O₂ ------> 2H₂O

But now there is 2 atoms of hydrogen in reactants side but 4 in product side. So we will multiply with 2 in Hydrogen in reactant side.

2H₂ + O₂ -----> 2H₂O

Now there are 4 atoms of hydrogen on both sides and 2 atoms of oxygen on both sides.

So this is completely balanced reaction.

This was a very simple reaction, try to balance more from your NCERT book.

Only thing you have to do is to balance all the elements one by one in any reaction. First balance one element then other and then recheck your reaction to make sure that there is no error.

TRY TO BALANCE THIS...

Zn + HCl ---> ZnCl2 + H2

Here there is 1 atom of zinc on both sides, 1 atom of hydrogen and chlorine in reactant side but 2 atoms of zinc and hydrogen on product side. After trying it see the answer below to check if it is correct...
