Making Connections: Chemistry Assignment By. Sujay Sukumar 5. a) When analyzing the graph‚ a relationship between the hydrocarbon chain of the alkane and its corresponding boiling point can certainly be noticed. There is a increasing correlation which can be explained using the theory that as each hydrocarbon chain gets bigger‚ there are more atoms and thus more electrons which contributes to higher dispersion forces and therefore a higher boiling point which is clearly seen through the graph.

Chemistry of Fireworks By Anuradha Sahu Everyone enjoys the amazing firework shows on the Fourth of July with the beautiful vibrant colors and sparks every year. Fireworks have been part of this world for a very long time. They have been used for enjoyment and for signalling purposes. Every culture has their own significance and use of fireworks. But all fireworks have something in common; the chemistry that makes them work. No matter where you find them‚ they are made up of the same compounds

The chemistry of hairspray What is hairspray: introduction Hair spray (or hair lacquer) is a common household aqueous solution that is used to keep hair stiff or in a certain style. Weaker than hair gel‚ hair wax‚ or glue‚ it is sprayed to hold styles for a short period of time. Using a pump or aerosol spray nozzle it sprays evenly over the hair. Hairspray was first developed and manufactured in 1948 by Chase Products Company‚ based in Broadview‚ Illinois.Its active ingredient is a suitable

Importance of Chemistry? What is the importance of chemistry? Why would you want to learn about chemistry? Chemistry is the study of matter and its interactions with other matter and energy. Here’s a look at the importance of chemistry and why you should study it. Answer: Chemistry has a reputation for being a complicated and boring science‚ but for the most part‚ that reputation is undeserved. Fireworks and explosions are based on chemistry‚ so it’s definitely not a boring science. If you take

(IHD) was used to generate a numerical value that determined various combinations of double bonds‚ triple bonds‚ and rings within a given molecule. The general formula for IHD is as follows: IHD = 2n+2-X2 n = number of Carbon atoms X = number of Hydrogen atoms (Oxygen atoms are ignored) Once the formulas were obtained‚ the experiment was started by finding the boiling point of the unknown liquid “D” and the melting point of the unknown solid “C”. Results were used to identify the identities

Clinical Chemistry When people consider their careers in the health care field‚ most of them would think about being a physician‚ a nurse or a surgeon. Individuals with interest in the health care field are not aware of clinical laboratory science. I am one of those individuals who don’t know much about clinical laboratory science before. After taking the class “Introduction to Clinical Laboratory Science”‚ I start to realize that clinical laboratory scientists are just like other health care members
