the “right stuff”. In 1959‚ John Glenn rose to fame as part of the Mercury 7‚ a group of 7 men picked to be America’s first astronauts. The Mercury 7 were as popular as movie stars are today. John’s flight on the Friendship 7 mission on February 20‚ 1962‚ gave him the title of being the first American to orbit the Earth and the fifth person in space. John became a national hero. John is the last living astronaut of the Mercury 7 and I sat down with him to discuss all of his accomplishments over

The purpose of this experiment was to observe how the change in solvent polarity affects the rate and to determine the kinetics of a solvolysis reaction. In this experiment‚ we used 1-chloro-1-phenylethane in acetone in one reaction with 50% ethanol-50% water and in another reaction with 40% ethanol-60% water. To monitor he rate of reaction‚ we would need the concentration of the alkyl chloride at the beginning of the reaction and at a time t‚ but since we did not determine the concentrations

Experiment 8 “Lipids” and the purpose of the lab is to become familiar with the properties and reactions of certain lipids called fats or oil. For this lab‚ students are testing the properties and reactions of lipids and soap will be prepared and its properties will be tested. To begin the experiment‚ place 5 mls of water‚ ethyl alcohol‚ chloroform‚ and toluene in to four clean test tubes and add 1 drops of cottonseed oil to each test tube. Shake it and record your observation. To do part B‚ in three

Acid and Bases 1 Determining Acids and Bases SNC-2D1 April 02‚ 2013 Acid and Bases 2 Purpose The purpose of this chemistry lab is to investigate and find patterns/tendencies between substances Introduction An acid is a solution that has more free hydrogen ions (H + ) than hydroxyl ions (OH - ) and a pH less than 7. A base is a solution that has less free hydrogen ions (H + ) than hydroxyl ions (OH - ) and a pH of more than 7. In the late 1800s‚ the Swedish scientist Svante

Hardware firewalls can protect computers on a local area network and they can be implemented without much configuration difficulty. Software firewalls are installed on individual computers and they need sufficient configuration to be effective. Software firewalls contain a set of related programs‚ usually located at a network gateway

Naming Chemical Compounds General Information: Scientists all around the globe use a standard method for naming chemical compounds. The standards were set up by an international committee sponsored by the International Union of Pure and Applied Chemistry (IUPAC). Having this standard makes life easier for people who use these compounds everyday. It would be tough to set up any experiment if scientists everywhere used different names for the same compound. It would also make the lab a much
