Question

here's the situation: five chemists are looking for something that they each want to study. one chemist is an organic chemist, the other is a biochemist, the third is an environmental chemist, the fourth is an industrial chemist, and the fifth is an analytical chemist. they found five items that need to be studied and these items are listed below. help these chemists look for an item to study to which is appropriate for their field. justify your answer.

a. cause of ozone depletion

b. the kind and amount of minerals present i drinking water

c. uric acid

d. chemicals needed in the making of toothpaste

e. fossil fuels

....many thanks

Answer 1

By elimination I’d say

A: Env. Chem.

B: Anal. Cem.

C: Biochem.

D: Ind. Chem

E: Org. Chem

But these subjects are no one man job but multidisciplinary team work on them

a. cause of ozone depletion is an environmental problem

Definitely environmental chemist (organic chemist – uses ozone in chemical synthesis)

b. the kind and amount of minerals present i drinking water

Definitely analytical chemist

c. uric acid

It is a very important molecule in metabolic processes – biochemist

Organic chemist – how to make in an artificial way

d. chemicals needed in the making of toothpaste

industrial chemist: how to produce it on an large scale

biochemist – effects of the chemicals on human health

organic chemist (and biochemist) – what is the best formulation?

analytical chemist – composition of the toothpaste

environmental chemist: impact of the production (waste) on the environment

e. fossil fuels

Fossil fuel provides the raw materials of almost any chemical synthesis - mainly organic chemist.

Industrial chemist - how to extract it from soils

Analytical chemist – what is the composition after each step of purification

Biochemist – searches for enzymes present on the soils in order to use them in biosynthesis

Environmental chemist – limits the impact of the exploitation on the… environment, he also helps to “clean” the site when the production stops.

Answer 2

cause of ozone depletion would be environmentalist

minerals present in water is analytical chemist

uric acid is definitely o-chem

toothpaste is biochemical

fossil fuel is industrial

Answer 3

organic - fossil fuel   = f.f contain hydrocarbons and other org.substances

environmental - cause of ozone depletion = ozone depletion is environmental problem

biochem.  -   uric acid = its exeretory substance of many organism & takes part in many biochemical reaction

industrial  -  chemicals needed in making of toothpaste = for toothpaste industry

anlytical  -  kind & amount of minerals present in drinking= for the analysis of minerals
