Job descriptions
- chemistry,biology,drugs and toxicology.
- analysing samples, such as hair, body fluids, glass, paint and drugs, in the laboratory
- sifting and sorting evidence, often held in miniscule quantities
- recording findings and collecting trace evidence from scenes of crimes or accidents
- justifying findings under cross-examination in courts of law
- techniques such as gas and high performance liquid chromatography, scanning electron microscopy, mass spectrometry, infrared spectroscopy and genetic fingerprinting
Forensic Science
What type of schooling & list of things a forensic science does!
- related to chemistry by uncovering information from physical evidence.
- college and training
- bachelor's degree
- master's degree
- doctoral degree (sometimes)
Examples
blood analysis
DNA Forensics in
Criminal Cases
Firearms Analysis
Mitochonrial DNA
- in the lab analyzing types of evidence, writing reports and presenting in court
- attend crime scenes
- work for federal, state and local governments etc..
- forensic scientist generally specializes in one area of forensics, DNA forensics or toxicology for example. A bachelors degree is sufficient to enter the field, masters degrees in forensic science are also available.
- forensic pathologist is an M.D. who determines cause of death in cases of a suspicious death (also called a coroner or medical examiner).
- forensic anthropologist is someone with a Ph.D. in anthropology who most often examines skeletal remains. Most of these are university or college professors who consult with the criminal justice system.
Hess contribution
- 1830 took chemistry full-time researching and teaching
- became a professor at Saint Petersburg Technological Institution
- famous paper outlining his law on thermochemistry, published 1840
- progenitor for first law of thermodynamics called Hess's Law
- Hess Law states that the enthalpy change for a reaction is the same whether it occurs by one step or by many other steps
studied medicine and looked into chemistry and geology
spent one month in the lab of Berzelius and became very good friends with his mentor Jons Jakob Berzelius

When phosphoric acid (a tri-hydrogen acid) is neutralised with a base, the hydrogens are neutralised in 3 steps.
H3P04 + NaOH -> NaH2PO4 + H2O, this is step one, and will give X amount of heat.
NaH2PO4 + NaOH -> Na2HPO4 + H2O, this is step two, and will give Y amount of heat.
Na2PO4 + NaOH -> Na3PO4 +H2O, this is step three, and will give Z amount of heat.
Therefore X+Y+Z will give the total heat or the constant summation of heat.
