Answer:
Chemistry teacher
Pharmaceuticals
Biochem/biotech
Materials science
Food chemist
Explanation:
Chemistry teaching
Teaching jobs in chemistry can range from teaching in public middle and high schools (bachelor’s degree required) to junior or community college (master’s degree required) to the university level (doctorate required). At the university level, you get to do research along with your teaching responsibilities.
Pharmaceutical/chemical sales
If you like chemistry but don’t enjoy being in the lab, then sales may be the job for you. Somebody has to sell all those chemicals and medicines, and buyers like to deal with somebody who knows their science.
Biochem/biotech
Biochemists and biotechnologists work in research developing new genetic tests, work in the genetic engineering (cloning) area, and are involved in the development of new drugs.
Materials science
Material scientists study the composition and structure of various materials with the goal of developing new products or improving existing ones.
Food chemist
Food and flavor chemists work in the research and development of new foods or keeping food fresh. Chemists test food additives and preservatives, develop new flavors, and analyze food for nutrient levels or the presence of contaminants.

Answer: Option (B) is the correct answer.
Explanation:
Degree of randomness of the molecules of a substance is known as entropy. More is the kinetic energy between the molecules of a substance more will be the degree of randomness.
Therefore, when a substance is present in a gaseous state then it has the maximum entropy. In liquid state, molecules are closer to each other so, there is less randomness between them.
On the other hand, in solid state molecules are much more closer to each other as they arr held by strong intermolecular forces of attraction. Therefore, they have very less entropy.
- When liquid water is formed from gaseous hydrogen and oxygen molecules then gas is changing into liquid. So, there is decrease in entropy.
- When
decomposes then the reaction will be as follows.
Since, 1 mole is producing 2 moles. This means that degree of randomness is increasing as both the molecules are present in gaseous form.
- In formation of a precipitate, aqueous solution is changing into solid state. Hence, degree of randomness is decreasing.
- Rusting of iron also leads to the formation of solid as it forms
.
Thus, we can conclude that decomposition of gas to 
gas is the process that is expected to have an increase in entropy.
Lo afect porque cuando la temperature aumenta, el volumen aumentará, luego, cuando we mantiene la presión, es constante. Calentar el gas aumenta la emergía cinética we law partículas, lo que have que el gas se expanda.
Espero que esto ayude :)
