Heat of Neutralization Introduction: The purpose of this experiment was to measure‚ using a calorimeter‚ the energy changes accompanying neutralization reactions. In order to measure the amount of heat produced by a reaction‚ an instrument called a calorimeter was used. The calorimeter used in this experiment was somewhat rudimentary. It was constructed as shown in the following picture: After finding the heat capacity of the calorimeter‚ the student and partner neutralized two acids and

Global Warming Global warming is the warming of the earth’s atmosphere. For many years humans have been blamed for causing global warming. Global warming‚ however‚ can be caused by natural effects. One reason is that the earth is constantly going through periods of warming and cooling. Second the two most abundant greenhouse gases water vapor‚ and carbon dioxide both occur naturally. Third the earth is not the only planet

I. Introduction Pressure is the application of force to a surface ‚ and the concentration of that force in a given area . A finger can be pressed against a wall without making any lasting impression ; however ‚ the same finger pushing a Thumbtack can easily damage the wall ‚ even though the force applied is the same ‚ because the point concentrates that force into a smaller area. Volume is the quantity of three-dimensional space occupied

Chemistry Module Six: Thermochemistry and rate Study sheet for the test G.01: Thermo-chemistry I. Temperature and Thermal Energy Temperature is a measure of the average kinetic energy of the particles in a sample of matter. The greater the avg. kinetic energy of the particles in a sample of matter‚ the higher the temperature of that matter. Some temperature scales are Fahrenheit‚ Celsius and Kelvin. Thermal energy is the measure of the total kinetic energy in a sample. And Temperature

It is better to prevent waste than to treat or clean up waste after it has been created. Energy requirements of chemical processes should be recognized for their environmental and economic impacts and should be minimized. If possible‚ synthetic methods should be conducted at ambient temperature and pressure. Chemist Vilas Pol came up with an environmentally green method that breaks down plastics and transforms them into a highly usable substance for society. Chemist Vilas Pol inserted plastic bags
