Question

So2+H2S+H20 balance the equation
​

Answer 1

Answer:

We want to balance the equation  2+2=+2.

It can be seen that on the RHS, the number of hydrogen atoms is twice the number of oxygen atoms.

⇒  On the LHS the number of molecules of  2  should be twice the number of molecules of  2.

So, as an intermediate step, we tentatively put  2+22=+2.

Now we see that there are four atoms of hydrogen and two atoms of oxygen in the LHS.

⇒  We should have two molecules of water on the RHS.

So, we modify the equation to  2+22=+22.

Now there are three sulphur atoms on the LHS.

⇒  There should be three sulphur atoms on the RHS also.

So we get the balanced equation  2+22=3+22.
