Chemical Activity.
1. Abstract.
In the chemical activity lab, we needed to find out which compounds would react with the given elements. We hypothesized that zinc (Zn) would react with copper nitrate (Cu(NO3)2) and lead nitrate (Pb(NO3)2). We were given six compounds of various nitrates and we had to put each nitrate in their own designated wells so we could later add the other elements such as: Copper (Cu), Magnesium (Mg), Iron (Fe), Lead (Pb), Nickel (Ni), and Zinc (Zn), to see which would react with the various nitrates. After we experimented, we got half a dozen reactions. These reactions were between iron and copper nitrate (iron turned black), zinc and copper nitrate (formed black fuzz around it), lead and copper nitrate (formed a bit of black fuzz on it), zinc and iron nitrate (zinc turned reddish, while the nitrate turned darker yellow), zinc and lead nitrate (formed a huge layer of black and white fuzz), and also magnesium and lead nitrate (formed black and white fuzz). Our hypothesis was partly correct, but there were also other reactions that also took place.
2. Hypothesis.
We hypothesized that zinc (Zn) would react with copper nitrate (Cu(NO3)2) and also lead nitrate (Pb(NO3)2). We also thought that magnesium (Mg) would react with lead nitrate (Pb(NO3)2). Also, we hypothesized that not many reactions would occur with the elements and compounds given.
3. Procedure.
1. We first placed a micro plate on top of a thin sheet of white paper. After doing this, we labeled the elements and compounds on the rows and columns of the micro plate, in order to organize our reactants.
2. By using a plastic micro tip pipet, we place 15 drops of each kind of nitrate into their proper columns.
3. We then placed copper, iron, lead, magnesium, nickel, and zinc strips in each row.
The Failures of Life in a Modern Society A common theme in many novels is for the protagonist to come to some sort of realization about life, therefore enriching and fulfilling some goal or desire in his own life. Most of the time he will learn a lesson, realize some truth, or derive some meaning ...
During the late 1880's in London England a serial killer nicknamed "Jack the Ripper" murdered an unknown number of prostitutes; all the victims were strangled prior to the mutilations. The killings occurred in the districts of Whitechapal, Spitfields, Adgate, and the city of London. At the time of ...
