(Name) (Course Name) (Instructors Name) (Date) Summary of chemistry lab report Introduction The two factors which affect the yield of products in a chemical reaction is the amount of starting materials (reactants) and the percent yield of the reaction. Many experimental conditions for example temperature‚ and pressure can be adjusted to increase yield of the desired product‚ in chemical reaction‚ but because chemicals react according to fixed mole ratios( stoichometrically)‚ the only limited

Using advanced techniques‚ very complicated structures for proteins‚ enzymes‚ DNA‚ and RNA have been determined. Molecular geometry is associated with the chemistry of vision‚ smell and odors‚ taste‚ drug reactions and enzyme controlled reactions to name a few.

halogens. They are all prone to hydrolysis‚ and ionise to give rise to polyhalogen ions. No interhalogen compounds containing three or more different halogens are known[1]‚ although a couple of books claim that IFCl2 and IF2Cl have been obtained‚[2][3][4][5] and theoretical studies seem to indicate that some compounds in the series BrClFn are barely stable.[6] 3 A nitrate test is a chemical test used to determine the presence of nitrate ion in solution. A common nitrate test‚ known as the

Chemistry Ozone Depletion Ozone depletion describes two distinct but related phenomena observed since the late 1970s: a steady decline of about 4% per decade in the total volume of ozone in Earth’s stratosphere (the ozone layer)‚ and a much larger springtime decrease in stratospheric ozone over Earth’s polar regions. The latter phenomenon is referred to as theozone hole. In addition to these well-known stratospheric phenomena‚ there are also springtime polartropospheric ozone depletion events. The

and open-chain (acyclic) form within aqueous solution. The ring of D-glucose consists of 5 carbons and oxygen which each carbon is linked to a hydroxyl group with exception of the 5th carbon which is linked to a methyl-hydroxyl group. D-Glucose has 4 chiral centers when it is in ring form which the anomeric carbon appears at C1 which lead to the structure of α(axial‚ down) and β(equatorial‚ up) position 2. The ratio of this anomer exists within the aqueous state of α: β is 36:64 and interconvert
