1315-022 For experiment one‚ The Determination of the Percent of Water in a Compound‚ the sole purpose of conducting this experiment was to determine the percent of water found in compounds such as Magnesium Sulfate‚ Copper Sulfate‚ and so on. Along with determining the percentages of the hygroscopic compounds the experiment allowed for the exploration of separation of hydrogen bonds to ionic solids through the use of heat. The reason that the water clings to the ionic compounds is due to its polarity

Francine Penny Patterson was born in Chicago‚ Illinois in February 13‚ 1947. She is the second oldest of seven children‚ her parents were C.H. Patterson and Frances Spano Patterson. Since she was little she felt attracted for animals and nature. In 1970 she got her bachelor’s degree in psychology at the University of Illinois at Urbana Champaign‚ two years later‚ she earned her Ph.D. in Developmental Psychology from Stanford University. Since then she started her long journey along with the

Pennies are easily spent and worth one cent‚ so if I was you I wouldn’t let that precious penny walk out of my life. Pennies are very expensive to produce. We have spent over eighty million dollars over the production of pennies‚ while pennies are only worth one cent. Even though some people want to get rid of the penny‚ it would be better if we keep it because it is apart of or culture. Also‚ we could avoid price increases from rounding up‚ and pennies are good for charities. Many people have

1) What are the core principles/characteristics of any project and why are they important? (8 marks). Ans:-The word project comes from the Latin word projectum from the Latin verb proicere‚ "before an action" which in turn comes from pro-‚ which denotes precedence‚ something that comes before something else in time. The word "project" thus actually originally meant "before an action". A project is characterized as a community oriented endeavor‚ including research or outline that is precisely wanted

the brave‚ fast thinking hero’s. The show’s main female character‚ Penny‚ is sexualized and objectified throughout the series. The show focuses solely on her social capabilities and how she physically looks. Penny is merely on the show to be a sex object. The Big Bang Theory also exemplifies the stereotype that women cannot be both intelligent and sexual. The men on the show are science geniuses who are continuously rescuing Penny from her irresponsible lifestyle. The show also discusses how all the

experiment‚ the crystals were blue. During the heating‚ the crystals turned white which means that they lost their water molecules. The source of hydrated copper sulphate consists of both small grains and large grains of the salt. Therefore during the heating process‚ the smaller grains of the hydrated salt turned from blue to white in just 1 minute. In other words‚ there is an uneven heat distribution‚ which give rises to inconsistent colour of the hydrated salt (i.e. there were a few white speck

Should the U.S. Government Keep the Penny in Circulation? Annoying cashiers was something my siblings and I did quite unintentionally as kids. Down the block from the street we lived on‚ there was a little convenience store that sold Italian ices‚ ice cream bars‚ and a variety of assorted goodies; on hot summer days‚ we would gather what little change we could find in the couch cushions and pay for our selected treats with pennies‚ nickels‚ dimes‚ and‚ if the cashier was lucky‚ quarters. That was

Experiment 6 Title: Preparation of bis(acetylacetonato)copper(II) complex Objective: To synthesize the bis(acetyacetonato) copper(II) complex Theory/Background: All metal ions in solution are ’associated’ with water. The water molecules can also be weakly bonded or more strongly as a ligand to form a complex ion‚ and these can also present in solid ’hydrated’ salts of crystallization. E.g Copper(II) nitrate (Cu(NO3) 2.3H2O). A complex ion has a metal ion at its centre with a number
