The electromagnetic spectrum is made up of six different types of waves. Radio waves‚ Microwaves‚ Infrared waves‚ Visible light‚ Ultraviolet light‚ X-rays and Gamma rays. The radio waves are used to transmit radio and television signals. The infrared waves are used to tell temperature of areas. Visible light is all the colors that we can see. Ultraviolet light can help things grow but to much can cause diseases such as skin cancer. X-rays are used as a tool to find broken bones or take pitchers

CYBER TERRISOM INTRODUCTION: Cyberterrorism is the use of Internet based attacks in terrorist activities‚ including acts of deliberate‚ large-scale disruption of computer networks‚ especially of personal computers attached to the Internet‚ by the means of tools such as computer viruses. Cyberterrorism is a controversial term. Some authors choose a very narrow definition‚ relating to deployments‚ by known terrorist organizations‚ of disruption attacks against information systems for the primary

aqueous layer can then be removed and the pure substance can be obtained through crystallization. In this week’s lab a mixture of carboxylic acid‚ phenol‚ and a neutral substance were separated from an ether solution. First‚ the carboxylic acid was ionized with a weak base and removed. A strong base was then applied to the mixture to allow the phenol to ionize and precipitate into the aqueous layer. This layer of aqueous solution was then extracted which left the neutral compound in the ether solvent

ester and a fluorescent dye. Here’s the sequence of events when the two solutions are combined: 1. The hydrogen peroxide oxidizes the phenyl oxalate ester‚ resulting in a chemical called phenol and an unstable peroxyacid ester. 2. The unstable peroxyacid ester decomposes‚ resulting in additional phenol and a cyclic peroxy compound. 3. The cyclic peroxy compound decomposes to carbon

Moles 1.How is molar mass calculated and why is it useful? You have to multiply the atomic weight of each element by the number of atoms that it contains in a compound. Molar mass is useful because its used to change a measurement of mass to an amount of a substance such as the number of particles. 2.Define a mole in chemistry and give 3 examples equivalent units that are used in chemical calculations. A mole measures the amount of a substance. Three examples that are equivalent to a mole is molar

able to use infrared satellite imagery. Infrared satellite imagery is able to look down on an open area and see what is located under the surface of the ground. Explorers had used this to uncover what the old civilizations looked like through the satellite. When a Egyptoligist named Sarah Parcak‚ and people in her team looked at an area they selected‚ "They found 1‚000 tombs‚ 17 potentially buried pyrimids‚ and about 3‚000 settlements."(Source 3‚ Paragraph 3) One thing that the infrared satellite imagery
