Chemical Periodicity ------------------------------------------------- ABSTRACT The experiment chemical periodicity shows the properties and reactions belonging to group IA‚ IIA‚ and IVA. Proper procedures and observations were done to determine the solubility‚ physical state‚ color‚ and appearance of the compounds namely Li2CO3‚ Na2CO3‚ K2CO3‚ CaCO3‚ and BaCO3. The results shows that Li2CO3‚ Na2CO3‚ K2CO3 were soluble in water‚ while MgCO3‚ CaCO3‚and BaCO3 were not soluble. All of these compounds

close look at my Resume will indicate that I majored in the exploitation of oil and gas fields in my undergraduate program and specialized in petroleum engineering‚ a similar specialty‚ in my Master’s program. It may well be asked why I maintain such a close affinity with petroleum. The answer is simple and straightforward—because I was born and I grew up on an oil field and I have cherished a deep love for all that it represent. Even as a child‚ I had a habit of watching for hours how beam-pumping

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

Jhavon Crenshaw Professor Madden English Composition 30 September 2012 Sound Engineering As a future audio engineer‚ it is in my best interest to learn the techniques of audio production. For editing sound you need the proper equipment‚ whether it is software or hardware. In order to give sound a little flavor you will need to know about mixing. Mastering is what ultimately completes the sound. Equipment‚ mixing‚ and mastering are the most important steps in audio production. The majority

great importance in human development. Actually‚ human can not live without water within a certain time. Water quality management has been conducted since numeral disasters was caused by the water pollution hundreds years ago. Due to the physical‚ chemical and biological adverse impacts posed by urbanization and industrialization‚ the quality of the water resources become a global issue. One of the most important factors is the boom of global population that would cause serious scarcity of water.

The hypothesis If a chemical reaction occurs‚ then there will be indicators of a chemical change‚ was supported throughout this experiment. Throughout this experiment there were several reactions that took place‚ and an indicator of such chemical reactions could be seen throughout each one. The first piece of identifiable evidence was present in the first step‚ which was when copper (II) nitrate and sodium hydroxide were combined. When stirred‚ a blue precipitate formed at the bottom of the test
