2013 Title: Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and to associate chemical properties with household products. Procedure: In this experiment I used a 96-well plate to hold each of the chemical reactions that occurred during this lab. Using a pipet‚ I added two drops of one chemical with two drops of another chemical and observed the effects of each reaction. Data Table 1: Experimental Data Well # | Chemicals | Observations | |

10/22/2014 Physical Science Physical Changes I like physical changes more than chemical changes. Some reasons are‚ physical change is "easily" reversible‚ how liquids can become solid and vice versa‚ the solid disappears but just the application of heat can boil the water off and get the salt back in the same form. Therefore‚ I like physical changes more than chemical changes. I like physical changes more than chemical changes because physical change is "easily" reversible because physical changes involve

A Research on the Legacy of Intel and AMD Microprocessors From the introduction of the counting frame‚ or more popularly known as the abacus1‚ it was realized that the creation of a tool that is able assist in mathematical calculations will greatly increase productivity and efficiency needs of man2. The use of abaci continued for numerous centuries up to the years when early calculators made use of hole-placements in a dial to signify a count—similar to that of a rotary dial telephone3. As
