Nitrogen Nitrogen, symbol N, gaseous element that makes up the largest portion of the earth's atmosphere. The atomic number of nitrogen is 7. Nitrogen is in group 15 (or Va) of the periodic table. Nitrogen was discovered by the British physician Daniel Rutherford in 1772 and recognized as an elemental gas by the French chemist, Antoine Laurent Lavoiser about 1776. Nitrogen is a colorless, odorless tasteless, nontoxic gas. It can be condensed into a colorless liquid, which can be compressed into

Pooja Dutta ID #: 15132955 CHEM 262 Section: 5BD Infrared Spectroscopy Aim The objective of this lab was to create IR samples and obtain IR spectra of solid and liquid compounds. IR is usually used to determine the functional groups in an unknown molecule. Thus, this further helps elucidate possible structures for the organic compound. Once molecules are excited, their vibrational frequencies, bending, and stretching are measured to determine the functional groups in the presence of infrared ra

REVIEW 3 Chapter 4Exam 1February 28th, 2017 Describe the Cell Theory and the experiment that showed where cells originate. All organisms are composed of one or more cells, it's the basic structural and functional unit of all living organisms and they come about from cells that already exist. Robert Hooke ( 1600's) used the newly invented microscope, looked at thinly sliced cork from a tree through a microscope. He gave the name cellulae meaning small rooms. Anton Van Leeuwenhoek, shoekeeper, us
The Theory Of Evolution
The Theory Of Evolution
The Theory of Evolution The theory of evolution, as set forth by Charles Darwin in 1859, stated that all plant and animal life evolved over long periods of time from simple to more complicated forms through mutation and adaptation. He also taught that only the fittest of each species would survive. He further postulated that the first living cell evolved in a warm warm little pond and that it took billions of years for the present diversity of living things to evolve. At the time, it was thou

Purple Loosestrife
Purple Loosestrife The scene is breathtakingly beautiful, a thick brush of purple flowers blankets Canada's wetlands. This blanket silences the expected sounds of the wetland environment, birds chirping, ducks splashing, insects buzzing and animals thriving. This unnatural silence is disturbing, the favourite flowers that used to litter this landscape are no longer visible, the water that used to ripple continuously is perfectly still. The wetland is dead, except for this overpowering, hardy pur

Schizophrenia
Although the studies reviewed above generally confirmed the classic DA hypothesis of schizophrenia, it is important to examine these results in light of the more recent views of schizophrenia as a neurodevelopmental illness, involving dysconnectivity of multiple cortico-subcortical and intra- cortical networks. Although it cannot be definitively ruled out that the DA dysregulation revealed by these studies would stem from a primary abnormality of DA neurons, it seems more likely that these abnor
