Question:describe the layered structure of the atmosphere
The earths atmosphere is composed of a layered structure with a mixture of gases. The first layer, the troposphere, extends from earths surface to 15km above sea level. It is composed of mainly nitrogen, oxygen, carbon dioxide, argon and water vapour. Asw altitude increase temps decrease from 25 degree to minus 25 degrees. The next layer, the stratopshere, extends form 15km-50km above earths sea level. it is composed of mainly nitrogen,ozone and oxygen. as altidue increase, temps increase from - 25 degrees to 25 degress. THe next layer, the ionsphere comprises thje mesopher and thermosphere. the mesophere extends from 50 to 85 km above eaths sea level. as altituide increases, temps decrease form 25 degress to -100 degress. the thermosphere extends from 85 to 120km above earths sea leavel. as altitude increase, temprs increase form -100 to 25 degree. both are compose of No, O and o2.

the main factors that need to be considered are :
-common anions and cations
-turbidity
-total dissolved solids
-acidity
-dissolved oxygen
-biochemcial oxygen demand
-microrganisms
-hardness
Question:describe the differences between the alkanoic acid and alkanol functional group
Alkanoic acids have the funtional -COOH group (carboxylate group) and alkanols have a functional -OH group (hydroxy group). Alkanols have genra; formula CnH2n+1OH and alkanoic acids R-COOH with R being alkyl group.
