The good ozone protects us from the UV/ harmful radiations whereas bad ozone is an air pollutant.
Explanation:
- There are two types of ozone layer found in the earth's atmosphere extending from troposphere to stratosphere. They are good ozone and bad ozone.
- Bad ozone as mentioned earlier it is an air pollutant and found in the ground level of earth, most accurately the troposphere. Bad ozone is formed in the ground level of earth's atmosphere by the reaction between nitrogen oxides and organic compounds which are volatile
- The Good ozone is found in the stratosphere layer of the earth's atmosphere. They protect us from harmful radiations. Good ozone layer in the stratosphere of the atmosphere is being destroyed by hydrocarbons, CFCs, and human intervention
The empirical formula is CrCl₃.
Explanation:
To find the empirical formula we use the following algorithm.
We divide each percentage by the atomic weight of each element:
for Cr 32.8 / 52 = 0.63
for Cl 67.2 / 35.5 = 1.89
The result will be divined by the smallest number:
for Cr 0.63 / 0.63 = 1
for Cl 1.89 / 0.63 = 3
The empirical formula is CrCl₃.

A) It decreases because the distance between the nucleus and outermost shell increases
When two atoms of Florine combines, they share an electron pair to complete it's octet. This result is formation of single bond between two fluorine atoms. This process is exothermic in nature, and hence, heat is liberated during the process of bond formation. <span />
C2H6 is the most polarizable and other two are non-polar molecules
