Question

PbS + X O3→ PbSO4 + O2. The value of X is

Answer 1

Answer:

One can find the value of X by balancing the given equation.

PbS + XO3 → PbSO4 + O2

The given equation has,

• 1 Pb in the left side
• 1 S in the left side
• 3 O in the left side

And it has

• 1 Pb in the right side
• 1 S in the right side
• 6 O in the right side

Hence, the only element we need to balance is Oxygen.

As, we have 6 oxygen atoms in the right side and 3 in the left side.

We have to write 2 in place of X so that in total we have 6 oxygen atoms in the left side too.

Hence, the proper balance equation will be:-

PbS + 2O3 → PbSO4 + O2

And X = 2.
