Heat of Neutralization Lab Objective: The objective of this lab was to measure‚ using a calorimeter‚ the energy changes accompanying neutralization reactions. Background: Chemical changes are always accompanied by a change in energy‚ typically as heat. If the reaction releases heat (ΔH < 0) then the reaction is exothermic. If the reaction absorbs heat (ΔH > 0) then the reaction is endothermic. The quantity of heat is measured experimentally by having the reaction take place in an insulated container called a

end of my junior year we were instructed to write a critical lens paper. My English teacher persistently reminded us this was not an essay to be done at the last minute. I was unfamiliar with this assignment and at first glance it seemed fairly easy. With that in mind‚ I decided to hold off and focus my attention on other courses. As the due date was approaching‚ nerves set in. I immediately began working on a rough draft. The critical lens final was due Monday‚ giving me only the weekend to complete

of the metal was determined by the heat energy calculations. The heat capacity that was found matched closely to that of the lead. There were several possible sources of error that could be found throughout the lab. Some of the main errors as seen in question 7 that could have affected the results of the lab were the amount of water transferred with the hot metal‚ the metal cooling off as it was transferred from the calorimeter‚ the calorimeter lost heat to the surroundings as it was stirred

A Feminist Lens in MacBeth MacBeth written by Shakespeare can be viewed through a feminist lens. Lady MacBeth and the witches are very strong important characters in MacBeth. When Shakespeare wrote this‚ feminism wasn’t a huge important aspect at the time‚ but he wrote it based on what he thought of women. Witches are often thought to be evil or mean‚ and Lady MacBeth was portrayed as a character who was very strong and could easily manipulate other people. Lady MacBeth is a strong person when

1. I don’t think any firm can guarantee complete product safety‚ especially companies as large as Ford and Bridgestone-Firestone. Both these companies produce such a large quantity of products that something is bound to go wrong. Also‚ no matter how safe a product might be there still can be potential problems with user error. An example would be how no matter safe Ford makes a car‚ there is still potential for an accident if the driver is inexperienced or if there is bad weather. So usually it is

Millenials A person born before the World War II is called a baby boomer. This is between 1946 and 1964 as is approximated by the bureau of census in U.S. In addition‚ there are times when the name baby boomer is used in the context of culture. As a result‚ name does not have a precise definition‚ even in a territory ( Foot 45). Additionally‚ different individuals‚ scholars‚ organizations and groups have varied culturally and technically in their opinions regarding what makes up a baby

Canford Heats is situated in the temperate climate‚ where the warmest temperatures are on July and range from 12-22 °C‚ being within the sunniest part of the country‚ whilst coldest temperature is in February‚ from 2 to 8.3 °C. Dominant soil composition is acidic‚ mostly due to the past erosion‚ and is strongly leached (posolised)‚ along with soils predominant in valleys where the waterlogging is present or thicker clay layer which forms peaty gleyed podsolos.
