Chemical Reaction Kinetic Energy
633 wordsThe rate of a chemical reaction is the derivative of the extent of the reaction with respect to time, to measure the effect of concentration upon the rate of the reaction of peroxydisulfate ion with iodine ion; to determine the order of the reaction with respect to the reactant concentrations; and to obtain the rate law for the chemical reaction. Four reaction solutions are prepare as: 1 - Dilute 5 mL of 0. 2 M KI solution with 10 mL of distilled water in a test tube, add 3 drops of starch solut...

Amino Acids Dna Molecule
1,152 wordsIntroduction Deoxyribonucleic acid is contained in all cells. The structure of DNA makes gene transmission possible. Since genes are segments of DNA, DNA must be able to make exact copies of itself to enable the next generation of cells to receive the same genes. The DNA molecule looks like a twisted ladder. Each "side" is a chain of alternating phosphate and deoxyribose sugar molecules. The "steps" are formed by bonded pairs of purine-pyrimidine bases. DNA contains four such bases the purines a...

Sodium Hydroxide Hydrochloric Acid
600 wordsBack titration: Work to be done: To find out the atomic mass of a substance using a method called back titration. Chemicals and apparatus: Magnesium Beaker Glass Burette Distilled water Methyl red 0. 5 M sodium hydroxide, NaOH 1. 0 M hydrochloric acid, HCl Lab-work: The name of the experiment explains the way of doing it quite well. You do measure how much you have of the substances and then do the titration. My mission was to find out the atomic mass of magnesium. I took a sample and weighted i...
