Purpose: The purpose of this experiment was to test and observe the physical and chemical properties of gases‚ and to use these properties to identify these gases when they are encountered. Procedure: Create a data table similar to that in the lab assistant to record your observations. Gather the following lab equipment: Goggles‚ test tubes‚ 24 well plate‚ Gas assembly with copper and plastic tubing and a #00 stopper‚ short stem pipet‚ rubber stopper #00 with one hole and a pipet tip with

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

Physiological Effects of Steroids and Steroid Abuse Competition in sports is absolutely incredible. Some athletes go as far as using drugs illegally such as anabolic steroids‚ a synthetic derivative of the male hormone testosterone. However‚ major sports bodies like the Olympics‚ the NBA‚ the NFL‚ and the NHL ban the use of such substances. For this reason‚ it is helpful to know the physiological effects of steroids as well as negative consequences of steroid abuse. In their experiment‚ Anttila

“Is Density An Intensive Property Of Matter?” By: Mikal Hayden - Gates A. Introduction The first unit we learned in chemistry was Alchemy. In this unit I learned about the extensive and intensive properties of matter. An extensive property is a property of matter that depends on the changes of the substances shape or amount. An intensive property is a property of matter that doesn’t depend on the substances shape or amount. The purpose of this investigation was to prove that density is
