experimental techniques which can be used to tell us where the atoms are located in a molecule. Using advanced techniques‚ very complicated structures for proteins‚ enzymes‚ DNA‚ and RNA have been determined. Molecular geometry is associated with the chemistry of vision‚ smell and odors‚ taste‚ drug reactions and enzyme controlled reactions to name a few.

Chemistry and Us The world is surrounded by so many things and everything is made of chemicals. Chemistry is very vital because it helps us to know the composition and changes of matter. Every single day of our life passes through chemistry in many ways. Human body works through the chemical reactions happening inside it. When we breathe‚ eat and sleep there’s still the presence of chemistry. The oxygen and foods we take helps our body to work. Exchanges of gasses‚ breaking down of foods we

THE GOVERNMENT AND POLLUTION Pollution is a very tough topic in today’s market and in my personal opinion; Government should intervene for the following reason. Let’s take the example of a company that manufactures blue jeans at a factory location on a river. The problem is that‚ as a byproduct of its manufacturing operations‚ the factory dumps chemical pollutants into the river. But no single person or entity owns the river water‚ so there is no one to force the company to stop polluting. Moreover

Extraction of Aluminium Aluminium ore is called bauxite. Bauxite contains aluminium oxide‚ water‚ iron oxide and other impurities. The purified dry ore‚ called alumina‚ is aluminium oxide (Al2O3). The alumina must be molten for electrolysis to work‚ since the ions are not free to move in the solid state. Unfortunately‚ alumina has a high melting point (2040 °C) and it is not practical to do electrolysis at such a high temperature. In the middle of the nineteenth century it was found that alumina

The waves‚ caused by vibration of the molecules‚ follow sine functions‚ typified by the amplitude and wavelength (or frequency) Sound waves of equal amplitude with increasing frequency from top to bottom Reflecting on noise “Noise" derived from "nausea‚" meaning seasickness Noise is among the most pervasive pollutants today Noise is unavoidable for many

According to Australian Marine Conservation Society (2013b)‚ when plastics are in the ocean‚ it will slowly breaks down in to smaller pieces and being eaten by animals that live at the bottom or even to the birds that flies and eat the floating plastic debris.

White Pollution According to Oxford English Dictionary‚ the pollution means "spiritual or moral corruption (4th cent)‚" but the meaning of "white pollution" is very different. For people who does not know Chemistry very well and people who is not recycling‚ they will not have a idea what is white pollution. In addition‚ they will not know how harmful the white pollution is to the Earth. Actually‚ the white pollution means that the plastic things‚ like plastic bottle‚ plastic bags‚ plastic silverware

1 in vapour state sulphur partly exists as S2 molecule which has 2 unpaired electrons in the antibondind pi orbitals jus lyk oxygen and thus exhibits paramagnetism. 2 An interhalogen compound is a molecule whose atom contains two or more different halogen atoms (fluorine‚ chlorine‚ bromine‚ iodine or astatine). Most interhalogen compounds known are binary (composed of only two distinct elements). Their formulas are generally XYn‚ where n = 1‚ 3‚ 5 or 7‚ and X is the less electronegative
