textbook in 1789 on chemistry in it he introduced the Law of Conservation. He founded the 3 types of matter (solid‚ liquid‚ and gas). Along with this he also established the metric system. Lavoisier also made a lot of enemies because he had disproved various old theories. In experiment 2.1 we wanted to know if the mass of salt will

Conclusion The purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an

8. Terfenedine is an amino diol that is the active ingredient in the antihistamine Seldane. Mass spectral analysis of terfenedine shows a molecular ion at m/z = 471 and a peak at m/z = 472 which is 35.5% the height of the molecular ion. Terfenedine is known to contain C‚ H‚ O and N. (a) Suggest five molecular formulas for terfenedine. (b) Terfenedine has an even number of carbons and contains nine double bonds and four rings. Based on this additional information‚ what is the formula for terfenedine

DISTILLATION HISTORY • Distilling was used as early as 3500 BC in Mesopotamia where perfume makers had developed it as a technique for isolating the scented oils of flowers and plants‚ what we know as “attar”. • Around 1100 AD wine was first distilled to make spirit by Irish monks who travelled around Europe. • The results of distillation were considered to have magical powers and this led to alcohol being called “water of life” or “usige beatha” in Gaelic‚ “eau de vie” in French

Lab for Chemistry 221 Lab: How much sugar is in a Can of Coke? Abstract: A 50mL (we used 100mL) volumetric flask was used to determine the amount of sugar in a can of Coke per mL in 5 different solutions. Using the calibration curve we determine the amount of sugar per mL in a can of coke. This experiment concluded that there is 43.83g of sugar in a 12oz can of Coke. Introduction: This experiment was conducted to determine the amount of sugar in a can of Coke and to and use a calibration
