2nd Year Chemistry Handbook - NUI Maynooth

Florence flasks, AKA boiling flasks Also known as a boiling flask, the Florence flask has a round bottom and a long neck. Investigating catalyst behaviour, specifically that of enzymes. Departmental Registration All students must register with the department for practical classes and tutorial classes.

In Maythe DEA shut down two major suppliers of precursors in the United States, seizing 25 metric tons of ephedrine and pseudoephedrine from Clifton Pharmaceuticals and cases of pseudoephedrine from X-Pressive Looks, Inc.

There is a small line on the neck that indicates how far to fill the bottle use the bottom of the meniscus. Mistakes cannot be rectified once grades are uploaded onto the university system! In order to progress to the next year of study a student must achieve the pass mark and fulfill all the requirements of their current year of study.

To use a balance to determine the weight of a chemical, first put the empty container that the chemical will be in on the balance. A small droplet of acid could splash out of the container at any time. Students should check this regularly, as the Department and other University offices use this e-mail to communicate with students.

Contact details for all of our staff are available on our website cited above. Get a glass rod into the test tube, stir the solution, rub the inside of the tube with the glass rod, agitate that solution. It is used to hold liquids and can be easily swirled and heated. Medicinal uses of coordination complexes.

Chemistry laboratory hand book with Suspected Cases of Plagiarism: The lack of acetic anhydride has caused clandestine chemists in some countries to substitute it for lower quality precursors such as acetic acid and results in the formation of impure black tar heroin that contains a mixture of drugs not found in heroin made with pure chemicals.

Material covered includes the first law of thermodynamics, the temperature dependence of enthalpy, entropy, the second law of thermodynamics, the Gibbs free energy function and the relationship between the Gibbs energy and equilibrium.

It is important to inform staff of any significant ongoing issues, personal or otherwise, that may be affecting your studies, so they can help you deal with such issues by directing you to the proper channels e.

Amphetamines[ edit ] The practice of clandestine chemistry to synthesize controlled substance analogues and circumvent drug laws was first noticed in the late s, as types of drugs became controlled substances in many countries.

They also commonly have lips around their rims and markings to measure the volume they contain, although they are not a precise way to measure liquids.

Page 14 of 20 Student Attendance With reference to the University regulations regarding attendance, quoting directly from the University Student Handbook,: Information in the notebook which came from a handbook for your compound might say, for alcohol meaning ethyl alcohols.

Any exercises given in the laboratory manual accompanying the practical details must be completed and returned along with the laboratory report. As a result, Bolivian lab operators are now using inferior substitutes such as cement instead of lime and sodium bicarbonate instead of ammonia and recycled solvents like ether.

If you add more hot solvent, good product will disolve, and trash will not. Leave the aspirator on and let air pass through the crystals to help them dry. The chemicals are always in some form of container and never placed directly on the balance.

Students may only appeal on the grounds that the allegation of plagiarism is unfounded, and appeals must be made in writing in the first instance.

Heroin[ edit ] Similarly, heroin-producing countries depend on supplies of acetic anhydride AA from the international market. In some instances students may finish up before 6pm, other times they will finish up after 6pm.

Do not let the whole setup tip over. Penalties imposed may involve suspension or expulsion from the course and from the University, in addition to the deduction of marks. For Health and Safety reasons absolutely no admittance will be allowed after these times. In response to stricter international controls, drug traffickers have increasingly been forced to divert chemicals by mislabeling the containers, forging documents, establishing front companies, using circuitous routing, hijacking shipments, bribing officials, or smuggling products across international borders.

The immediate market impact suggests that they had been providing more than 50 percent of the precursors used nationally to produce methamphetamine. The term moonshine generally referred to "corn whiskey", that is, a whiskey -like liquor made from corn.

History[ edit ] Ancient forms of clandestine chemistry included the manufacturing of explosives.Steve Zumdahl is the author of market-leading textbooks in introductory chemistry, general chemistry, honors-level chemistry, and high school chemistry. Recently retired from his long-time position as Director of Undergraduate Programs at the University of Illinois, he has received numerous awards for his contributions to chemical willeyshandmadecandy.com: Steven S.

Zumdahl. The American Chemical Society recognizes that this is not a true periodic table of the elements. The use of the periodic table format is for the sole purpose of communicating the benefits of.

The CRC Handbook of Chemistry and Physics is likely to be found on most scientific bookshelves around the world.

Contains more accurate and detailed information than any other single chemistry and physics handbook. This is a list of 27 basic pieces of laboratory equipment you would find in a general chemistry lab.
