A bond is formed when electrons are shared between atoms.
<h3>What is the number of unshared pairs?</h3>
A bond is formed when electrons are shared between atoms. This is what we call a shared pair. A lone pair or unshared pair is one that is domiciled on only one of the atoms in the bond.
Let us now look at the molecule shown in image 1;
- The number of unshared pairs in atom a is 0
- The number of unshared pairs in atom b is 2
- The number of unshared pairs in atom c is 0
Let us now look at the molecule shown in image 2;
- The number of unshared pairs in atom a is 1
- The number of unshared pairs in atom b is 2
- The number of unshared pairs in atom c is 3

I think the correct answer from the choices listed above is option B. Polymerization is the process of forming c<span>omplex molecules by the bond formation between monomers. There are two types of this process which are the addition and condensation polymerization.</span>
The balanced reaction is 2KClO3 --> 2KCl + 3O2
We first divide the 400.0 g KClO3 by the molar mass of 122.55 g/mol to get 3.26 mol KClO3. Next, we use the coefficients: 3.26 mol KClO3 * (3 mol O2 / 2 mol KClO3) = 4.896 mol O2. Multiplying this by the molar mass of 32 g/mol gives 156.67 g O2.
Percent yield = 115.0 g / 156.67 g = 0.734 = 73.40%
