Answer:
Monatomic ions are made up of only one atom per ion, whereas polyatomic ions are made up of numerous atoms per ion.
Explanation:
Answer:
Yes
Explanation:
There is a difference between the homogeneous mixture of the hydrogen and the oxygen in a 2:1 ratio and the sample of the water vapor.
In the homogeneous mixture of the hydrogen and the oxygen which are present in the ratio, 2:1 , the elements are not chemically combined. They are explosive also as both shows their specific properties. They can be separated by physical means (Condensation, diffusion).
On the other hand, in water vapor, the two elements are chemically bonded in a specific mixture which cannot be separated via physical means. Water has its unique properties and they can be separated by chemical means only.
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.
