Iron powder will react with cupric sulfate in a onetoone ratio (1 mole to 1 mole). The students will also be able to more easily visualize the size of a mole of iron and copper. The result obtained in this lab usually have less than a one percent error. Fe(s) + CuSO4 (aq) > FeSO4(aq) + Cu(s) Iron powder cupric sulfate ferrous sulfate copper In the reaction‚ iron will be the limiting reagent; it will be completely used up in the reaction. Cupric sulfate will be in excess; not all of it will be used up in the reaction

DNA DIGESTION AND ELECTROPHORESIS In this experiment we will be doing a process called as DNA digestion or also known as restriction digest. A restriction digest is a procedure used in molecular biology to prepare DNA for analysis or other processing. It is sometimes termed DNA fragmentation‚ scientists Hartl and Jones describe it this way: This enzymatic technique can be used for cleaving DNA molecules at specific sites‚ ensuring that all DNA fragments that contain a particular sequence have the

Electrophoresis of Amino Acids Introduction: Electrophoresis is a separation technique based on the movement of charged ions under the influence of an electrical field. This technique is primarily used for the separation of amino acids and peptides on the basis of their charge. All amino acids contain ionizable groups that cause the amino acids‚ in solution‚ to act as charged polyelectrolytes that can migrate in an electric field. The amino acids with a net positive charge will migrate toward

Marissa Arias Senior Rhetoric Graf-8 April 14‚ 2014 Gel II Manicure Many women and even some men love to get their nails done‚ but hate how much time it takes to dry and on top of that they are extremely easy to ruin and chip. There is a new type of manicure trending know as Shellac‚ Gel nails‚ or No chip. According to my cosmetology instructor Samantha Rudman‚ this process takes about 35 to 40 minutes but dries in seconds. Many individuals would love to know this process even the men that

Agarose Gel Electophoresis of DNA Topoisomers Introduction DNA can exist as different isomers that change the confirmation of the DNA’s structure. DNA can be in a linear confirmation this is a relaxed confirmation as the DNA can rotate about its axis unconstrained. It can also exist as a nicked circle this is also a relaxed confirmation as the DNA strands can again rotate freely with respect to one another. Covalently closed circular DNA or cccDNA exists as a supercoil this is because the covalent

Sodium hydroxide‚ also known as caustic soda‚[2][3] or lye‚ is an inorganic compound with the chemical formula NaOH (also written as NaHO). It is a white solid‚ and is a highly caustic metallic base and alkali salt. It is available in pellets‚ flakes‚ granules‚ and as a 50% saturated solution.[citation needed] Sodium hydroxide is soluble in water‚ ethanol and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air. Sodium hydroxide is used in many industries
