Title: Liquids and Solids Purpose: The experiment will help determine two important physical properties‚ boiling and melting point‚ of liquids and solids. Procedure: Before starting the experiment I gathered all materials appropriate for the experiment and prepare a safe environment for my experiment. I record the boiling point of the Isopropyl Alcohol and the melting point of powdered Acetamide with lab equipment such as the thermometer‚ capillary tube‚ beaker‚ test tube‚ and burner fuel

Biotechnology‚ Mapua Institute of Technology ABSTRACT In this experiment‚ solubility class of various organic compounds are to be determined. The main objective of the experiment is to identify an unknown compound through the use of preliminary tests such as examination of physical state‚ color‚ odor‚ and ignition properties. Also‚ solubility tests were used to further examine an unknown compound’s solubility class. In this experiment‚ the apparatus used are micro test tubes and droppers for mixing

Chem-102 Lab Dr. Sobhi Experiment #3: Spectrophotometric Determination of Tartrazine Purpose The objectives of this lab include- illustrating the use of the spectrophotometer in chemical analysis‚ and generating a standard‚ or calibration curve‚ then using that curve to determine the value of an unknown substance. The spectrophotometer is one of the most powerful tools used in chemistry to find the concentration of substances in solution. It compares the colors of a known and an unknown solution

area‚ the larger species it can support. Aim: To see how the size of an area affects the relationship between species diversity. Diversity is a range of different elements. Habitat size determines diversity relationship(Edition of Nature‚ March 28 2002). In the research of specie diversity ‚ it was found out that more productivity was done when two different types of species were in one area. It was also said that diversity goes down but as it goes down the productivity of the species increase. Variables:

treatments for alleviating jet lag: 1) doses of Vitamin B complex; 2) 10 minutes of meditation; and 3) 15 minutes of aerobic exercise. Each suggestive treatment is complete with a reasonable physiological rationale. I have come up with an experiment to test the 3 variables to figure out what treatments if any will work the best. My hypothesis is that all 3 of the suggestive treatments when done before flying on an airplane‚ will reduce the effects of jet lag. Experiment: A commercial airplane traveling
