Answer:
There are 6 non bonding pair of electrons present in Lewis structure of peroxide ion.
Explanation:
Ionic formula of peroxide ion is 
Total number of valence electron present in peroxide ion is 14 (12 electrons come from two oxygen atoms and another 2 electrons come from negative charges).
After fulfilling octet rule, Lewis structure of peroxide shows that each oxygen atom contains three non bonding electron pairs and a covalent bond.
Hence there are 6 non bonding pair of electrons present in Lewis structure of peroxide ion.
Lewis structure has been given below.

97% of earth's water is in the ocean. The rest could be found underground, in glaciers and ice, and in rivers and lakes
Answer:
Polyunsaturated
Explanation:
A fatty acid is a compound that is derivative from a carboxylic acid. The chain of carbons can have since 4 carbons to more than 20 carbons. The bonds between carbons can be simple, which are called saturated bonds, or double, or triple, which is called unsaturated bonds.
When a fatty acid only has saturated bonds between carbons, it's called a saturated fatty acid. If there is only one unsaturated bond, it's called an unsaturated fatty acid, and if there are two or more unsaturated bonds, it's called polyunsaturated fatty acid.
