Volatile Organic Compounds (VOCs) have become the greatest challenges to the preservation of the environment today. This group of chemicals is used in almost every sphere of life from industries‚ government institutions and domestically by both an ignorant and knowledgeable public. This paper aims to put to light examples of such compounds‚ look at the effect on the general populace and the environment and outline possible remedies to negative impacts. At the same time‚ it is important to look at

Date of Experiment October 7‚ 2012 Report Submitted: October 7‚ 2012 Title: Liquids and Solids Purpose: The purpose of this experiment is to determine the boiling point of liquids and the melting point of solids. Procedure: I got all of my materials together and set up. I poured rubbing alcohol in a beaker and rubber banded it with the thermometer. I logged the last bubble that came out of the capillary tubes. After that I crushed the acetamide and carefully put it in the capillary tube

Calculating the Density of Liquids II. Purpose/Background: The purpose if this lab was to determine the density of water and an unknown liquid. Density is defined as the mass of a substance divided by its volume. It is an intrinsive property of matter and is used to specifically characterize substances. III. Procedure: 1.We massed an empty 10mL graduated cylinder to the nearest .01g. 2.Then‚ we filled the graduated cylinder with 4.0-5.0 mL of distilled water‚ 3.massed it to the nearest 0.1
