Question

Pbs reacts with ozone and forms pbso4. as per the balanced equation, molecules of ozone required for every one molecule of pbs are

a.6

b.4

c.3

d.2

Answer 1

After balancing we get
3PbS + 4O3=3PbSO4
So in every 3 molecules of PbS we require 4 molecules of ozone

Answer 2

Answer:

The correct answer is option b.

Explanation:

The chemical equation for the reaction of lead sulfide with ozone follows:

$PbS+4O_3\rightarrow PbSO_4+4O$

By stoichiometry of the reaction:

1 mole of lead sulfide reacts with 4 moles of ozone.

So, 1 molecule of lead sulfide will react with $\frac{4}{1}\times 1=4$ molecules of ozone.

Thus, the correct answer is Option b.
