Synthesis of Aspirin and Oil of Wintergreen INTRODUCTION: Synthesis and use of organic compounds is an extremely important area of modern chemistry. Approximately half of all chemists work with organic chemicals. In everyday life‚ many if not most of the chemicals you come in contact with are organic chemicals. Examples include drugs‚ synthetic fabrics‚ paints‚ plastics‚ etc. Synthesis of Aspirin and Methyl Salicylate. The two compounds we will be preparing‚ aspirin (acetylsalicylic acid) and oil of wintergreen

Roentgen’s discovery of rays through the fluorescence some materials produce. Becquerel did a experiment surrounding several photographic plates with black paper and fluorescents he was going to leave the plates in the sunlight but due to an overcast in Paris he wrapped the plates and put them in a dark drawer. After he took it out he found that the salt had left very distinct outlines in photographic paper

Factors that affect how the PH changes during a titration experiment. Concentration of the alkali Having a higher concentration of alkali will mean that there will be more molecules closer together for the acid to collide with. This will speed up the reaction as collision theory suggests that molecules have to collide to react and if there are more molecules to collide with the reaction will happen faster as there is a higher chance of a collision. Volume of alkali An increase in volume would mean

Purpose: To Inform Topic: Chemical Warfare Intro 1) Chemical weapons are extremely toxic chemicals which differ from explosive weaponry. Middle ages and renaissance are documented to have used poisonous chemicals on individuals. Chemical warfare is use of chemical agents to kill or incapacitate the enemy. 2) Today I will inform you of different chemical agents. Since World War I‚ several types of agents have been developed into weapons. These chemical weapons include (I) Choking

“The American Dream” The American dream‚ isn’t this what everyone is chasing? Isn’t this why people work so hard and go to extreme lengths just to achieve this “Dream”? Owning a home‚ having a family‚ and basically living care free is the “dream” that is projected‚ but is this goal that so many people are told to strive for even obtainable? There is a belief that once this goal is achieve all the troubles will some how fly out the window‚ but sadly that isn’t true. The American dream itself

Be the Change You Want To See A lot of people associate change as a negative outcome but really change can be great. It’s all about your attitude toward the change. Before the change can take place‚ we have to start fresh by getting rid of old baggage and stuff. Let’s shred everything negative from your life so we can start over. Look in the mirror and write down what you see and what you want to change? Not necessary your facial features but your life. Steps for creating a change in your

Chemicals of Life • With the exception of water‚ virtually all chemicals of life are CARBON based • Molecules that contain Carbon are considered organic with some exceptions such as CO2 • Carbon has 4 valence electrons so it is oriented in a tetrahedron shape Sketch→ • Carbon can form up to 4 covalent bonds and can form long chains‚ rings‚ and branched chain molecules • Carbon acts as the backbone of biological molecules • Molecules that only contain carbon and hydrogen are known as hydrocarbons→

of this lab was to determine if a there is a change in mass when a gas is produced and determine if gas has mass. To conduct this experiment‚ the group must be careful not to let the Alka-Seltzer tablet get wet before the bottle is closed by wiping the lip of the bottle and the cap so it remains dry‚ or risk gas escaping into the air and not being captured by the bottle. Also‚ the group must be sure to close the bottle tightly with the cap‚ because gas may escape this way as well. During this investigation
