presentation entitled "The Environmental Impacts of Chemical Deicers and Road Salt". I was required to attend this presentation for my Environmental Issues class as well. The presentation was approximately 25 minutes long and included a powerpoint presentation. In the presentation itself‚ it stated the impacts of road salts and deicers‚ the state uses on the roadways during the winter months. The most commonly used road salt is sodium chloride‚ which is also the most inexpensive and readily available

A clothing iron‚ also called a flatiron or simply an iron‚ is a small appliance: a handheld piece of equipment with a flat‚ roughly triangular surface that‚ when heated‚ is used to press clothes to remove creases. It is named for the metal of which the device is commonly made‚ and the use of it is generally called ironing. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are

Liquids & Solids Pre Lab Questions: 3pts 1. What are the learning goals of this lab? The learning goal of this experiment is to view and experience the melting point and boiling point of different substances. 2. Why is acetamide not allowed in contact with your skin? What precautions does one have to take to work with this chemical? Acetamide is a carcinogen‚ which can cause cancer. Therefore‚ it should not be allowed to come in contact with a person’s skin. Any person working with this chemical

The Separation and Purification of Organic Compounds Sunshine Marie Introduction Each year‚ many thousands of new or unknown organic compounds are prepared or extracted from natural sources such as plants‚ fungi and animals. In order to identify an unknown organic compound or the components of a mixture of organic compounds‚ it is necessary firstly to separate and purify the compounds. At any given temperature‚ a certain number of molecules of a substance in the liquid state have sufficient

materials. Particles in each of the 3 states of matter behave differently. In a of particles. solid‚ the particles are very close and strongly attracted to each other. They can vibrate‚ but they cannot move from one place to another. They always stay in their positions‚ creating a defined shape and volume. In a liquid‚ the particles have weaker attraction and are not as close to each other as solids. They can move around in all directions so liquid does not have a defined shape‚ but their movements

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
