Analytical Chemistry is the branch of chemistry principally concerned
with determining the chemical composition of materials, which may be solids,
liquids, gases, pure elements, compounds, or complex mixtures. In addition,
chemical analysis can characterize materials but determining their molecular
structures and measuring such physical properties as pH, color, and solubility.
Wet analysis involves the studying of substances that have been submerged in a
solution and microanalysis uses substances in very small amounts.

In California, the DUI laws are written under the California Vehicle Code VC 23152 Alcohol and/or Drugs. The DUI law was codified back in 1935. The law distinguishes between a misdemeanor and felony.

Enzymes are very precise protein molecules with a high specificity
which are used to catalyse chemical reactions by lowering the
activation energy required for the reaction to take place. It is these
properties of being able to break down substances easily and bind
specifically to certain chemicals that make enzymes very useful in
many industries and practices throughout the world.

Anti-depressants are drugs that boost the brain chemical serotonin by blocking its re-absorption into cells that send it out as a signal transmitter. Sounds acceptable, right? Wrong. Many people experience serious adverse reactions to these drugs. This makes perfect sense considering the drug is altering the chemicals in your brain.

A food web is a network of food chains. There are some things we need to know about the food web. Each level of the chain is dependent on the adjoining levels. Autotrophs make their food from light or some form of chemical energy and are at the bottom of each food chain. These ...
