Chemical Formula Principles Chemical Formula is a system of chemical notation that was invented in 181 by John Jakob Berzelius. The system is based on the law of definite proportions”‚ states that all samples of a given chemical compound have the same elemental composition. It is also a way of expressing information about the proportions of atoms that constitute a particular chemical compound‚ using a single line of chemical element symbols‚ numbers‚ and sometimes also other symbols‚ such as

Wireless Local Area Network Background The first wireless computer communication network ALOHAnet (operational in 1971) was developed by Norman Abramson‚ a professor at the University of Hawaii. At first‚ the wireless LAN was so costly that it was just used as an alternative to the places where the cabling was difficult or impossible. Recent developments included industry specific solutions and proprietary protocols‚ but were replaced by various versions of IEEE 802.11. In 2009‚ 802.11

Harmful Chemicals in our Environment Over the past century humans have introduced a large number of chemical substances into the environment. Some are the waste from industrial and agricultural processes. Some have been designed as structural materials and others have been designed to perform various functions such as healing the sick or killing pests and weeds. Obviously some chemicals are useful but many are toxic and their harm to the environment and our health far outweighs their benefit to

Chemical Bonding Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent Bonds Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms‚ in contrast to the transfer of electrons in ionic bonds. Such bonds lead

Assignment 5 Sheet Harbour Chemicals Sheet Harbour Chemicals (SHC) manufactures chemicals used in the paint industry. The process involves three departments. Chemical A‚ which is purchased for $3 per liter‚ is processed through Department 1 in batches of 100 liters. Each batch of chemicals processed through Department A produces 70 liters of chemical B and 30 liters of chemical C. Chemical B is sold for $10 per liter. Chemical C is used in Department 2 to produce chemicals D‚ E‚ and F. Department 2

an object. An example of a physical property of an object would be the color‚ mass‚ solubility‚ volume‚ or the polarity of an object. A physical property can change the appearance of an object‚ but that does not mean that the chemical composition has to change. The chemical composition can remain the same. Physical properties are separated into two different categories. They are separated in to intrinsic properties and extrinsic properties. Extrinsic properties rely on the amount of material
