Lab 7: Determination of Water Hardness Using a Titrator Name: Kyndal Petrie Lab Partners: None Date of Experiment: July 19‚ 2013 Location: My house Course Number: Che112 Abstract: This experiment was to determine the hardness of the local water supply. I determined that from the 1mg of EDTA used to turn the mixture blue‚ that the water from my tap is moderately soft. Experiment and Observation: In this experiment I developed a familiarity with the concept

Tossed Salad Vs. Melting Pot In discussions of tossed salad and melting pot‚ a controversial issue is whether or not tossed salad is better than melting pot. Tossed salad represents multiculturalism. The tossed salad is colorful and it has unique and different ingredients it has the tomatoes‚ the lettuce‚ the cucumbers‚ the red and green and orange bell peppers and other ingredients. Each ingredient has its own unique color‚ texture and taste. What unites all these ingredients though is the

the melting glaciers poses a direct threat to my home. Island nations and coastal cities will suffer the inevitable if we do not act now. In six degrees‚ Mark Lynas warned the impending arctic tipping point‚ once passed‚ the melting of the glaciers cannot be reversed‚ leading to a loss of habitable environment. However‚ I believe that the situation is worse than what Lynas anticipated. Despite some efforts from the international to curb the increasing carbon emissions‚ glaciers are melting faster

“The USA was not a ‘melting pot’ but a ‘mosaic’ of different cultures in the period 1890-1910’ Do you agree? According to some historians‚ the USA in 1890 had become a ‘melting pot’ of different cultures‚ meaning that the people who had immigrated to America had left their old traditions behind to start a new country free from outdated laws; this idea was also linked to American Exceptionalism as America was ‘Exceptional’ for these reasons. Many historians argue against this idea as there is plenty

Experiment #6: Colorimetric Determination of pH Almira‚ Faerie Carleen Lucile L. Gallardo‚ Charlotte O. Group #6‚ Chemistry 18.1‚ MHEG1‚ Ma’am Arlou Angeles September 23‚ 2013 I. Abstract The acidity of the four unknown solutions were determined with the use of colorimetry using McIlvaine’s buffer solutions varying in proportion of its constituents (disodium phosphate and citric acid). These buffer solutions were subjected to the addition of corresponding pH indicators and the variation of

world’s ice is slowly melting‚ so that also means our glaciers are melting (shrinking). This is a problem worldwide. The oil‚ coal‚ natural gases‚ and fossil fuels we burn affect our atmosphere and increase the temperatures that melt our glaciers. If the glaciers continue to melt rapidly ocean levels will rise‚ there will be flooding‚ there also could be droughts. This is a very serious issue today but I’m just going to tell you about two places for now. How does the melting of glaciers affect people

Our Iceberg is Melting: Changing and Succeeding Under Any Conditions John Kotter and has produced a great book that contains a wealth of wisdom and insight. While it looks and reads like a simple book‚ it is anything but simple. The message which Kotter is able to make clear goes much deeper than the surface story of a colony of penguins in search of answers pertaining to their survival on an iceberg. He easily describes a scenario through a penguin colony that any person can relate to and think

CHEM 1105 Experiment 4: Determination of a Chemical Formula Introduction When atoms of one element combine with those of another‚ the combining ratio is typically an integer or a simple fraction. The simplest formula of a compound expresses that atom ratio. When two or more elements are present in a compound‚ the formula still indicates the atom ratio. To find the formula of a compound we need to find the mass of each of the elements in a weighed sample of that compound. For example‚
