Explanation:
its an ionic compound where N nitrogen is bonded to covalent molecules
Answer:
See whole explanation to understand
Explanation:
the reason why there is such a large jump from 2nd to 3rd ionization energy for calcium is because to remove the third electron, a larger amount of energy is required, since the shell is closer to the nucleus, and higher attraction exists between them. This is why the second ionization energy is 1125.4 and then the third IE is 4912.4 which is a very big difference. It's all about the elections and energy!!
It would be “To obey the law of conservation of mass”
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.
