S., North Hennepin Community College, based on participation in the Chem Ed DL summit hosted by the University of Wisconsin - Madison and Catholic University of America.In introductory chemistry, students learn stoichiometry. In this activity, it allows the students to read a webpage in order to aid them in making a connection between stoichiometry and when they use the same mathematical process during their every day life. Why they do not interfere with each other’s function. Drugs desired to cure some ailment in one organ in the body affect. They can be used in hard water as well as in acidic solution the reason being sulphonic and their calcium and magnesium salts are soluble in water but the fatty acids and their calcium and magnesium salts are insoluble.

This activity could be used prior to learning stoichiometry or after being introduced to stoichiometry. This activity was used at a community college, Introduction to Chemistry course (high school/pre-General Chemistry equivalent) with a class size of approximately 40 students.

The students were allowed 20 minutes to complete the activity where they read through the web page and had to come up with an example where they use dimensional analysis in their life.

Equnil is a tranquilizer and it is used for removing depression and hypertension. Morphine is an alkaloid and it is used as an analgesic. Sodium rosinate, Sodium silicate, Sodium Carbonate are added to laundry soaps to increase their leather forming ability. Glycerol is added to shaving soaps to prevent them from rapid drying.

Substances which are added to soaps to change their properties in order to make them more useful for a particular application are called the fillers Example:- i.

Aspirin prevents platelet coagulation and thus has antiblood clotting and therefore it is widely used to prevent heartattacks. Why it is safer to use soap from the environmental point view? Soaps are biodegrable while detergents containing branched hydrocarbon chains are quite stable, they are not degraded by microorganisms and hence causes water pollution in the rivers and other water ways. Pickles have a long shelf life and do not spoiled for months why? Plenty of salts and cod liver oil act as preservative. What is the function performed by histamine in the body?

For Example:- Cimetidine is called the antagonistic drug since it binds to reception site in stomach 10. This activity should be easy to adapt, this activity was performed during class in a computer lab, but could also be given as a homework assignment. The students were instructed to use these resources and then write down on a piece of paper an example of when they use the same math process as used in stoichiometry, during their every day life.

Enzymes have active sites which bind the substrate quickly and effectively. What are biodegradabed and non-biodegradable polymer. Non biodegradable detergents:- The detergents containing branched hydrocarbon chains are not easily degraded by microorganism and hence are called biodegradable polymers Example:- Sodium 4 – (1, 3, 5, 7 – tetramethyloctyl) benzene sulphonate. Explain the term, target molecules, or drugs forget as used in medicinal chemistry? Drugs that binds to the receptor site and inhibit its natural function are called the antagonistic drugs. Thus catalytic activity of enzyme is get inhibited.
