PHYSICAL SCIENCE I. HISTORICAL BACKGROUND A. Babylonians They recorded eclipses and they were able to predict future eclipses. They named the twelve divisions of the Zodiacs‚ divided the northern sky into constellation and gave their present names. Their priest recorded planetary motions especially those of Venus‚ geometry and mathematics were highly developed by these people. There were evidences of multiplication tables and tables of square and cubes. They created standards for measuring length

Hot-Can has developed a special double-chambered aluminium can which contains the beverage in the outer chamber and holds water and calcium oxide (quick lime) separately in the inner chamber. When the seal at the bottom of the can is depressed and broken‚ the water mixes with the quicklime‚ starting an exothermic reaction that heats the contents of the outer chamber by 50-55°C in just

The poem harmonium examines the relationship of a father and son. I think Armitage has written this poem for parents and children as they would be able to relate to the emotions in the poem. The Author uses the Farrand Chappelette which is a type of Harmonium or small organ to help him reflect the love that he has for his father. In the first stanza the poet talks about the Farrand Chappelette which was “gathering dust” telling us that it is getting old and it was due to be taken to the skip if Armitage

Goals The main goal of this project is to learn how to identify the properties of an unknown ionic compound. In order to do this successfully the group has to use a variety of methods and run several tests on the unknown compound. By doing this the group will be able to identify the different chemical and physical properties of the compound that will help obtain the identity of the specific compound given. The group will devise two syntheses of the compound‚ and compare them for cost effectiveness

Different elements give off different colors when heated because they all have different chemical properties‚ therefore‚ they will react differently under high temperatures. For example‚ [1] strontium‚ lithium carbonate‚ and strontium carbonate are often used in fireworks to create a red color. Calcium may be used to create orange‚ sodium for yellow‚ aluminum for white‚ barium chloride for green‚ copper for blue‚ strontium and copper for purple‚ and titanium for silver. Even though all elements give off

If the solution becomes cloudy or chalky‚ calcium carbonate was formed‚ indicating the presence of carbon dioxide in the flask. Qualitative Data Procedure step Observations Step

(a mixture of aluminosilicates) and heating the mixture to about 1500oC. The chemical reaction releases carbondioxide and partially melts the components to form solid lumps called clinker. The clinker is ground to powder‚ and a small quantity of calcium sulfate is mixed in. This mixture is known as Portland Cement. Chemically‚ its main components are 26% dicalcium silicates ( Ca2SiO4); 51% tricalcium silicates (Ca3SiO5); and 11% tricalcium aluminate (Ca3Al2O6). When water is added‚ a number of complex
