Purpose The purpose of this lab is to identify the different features that come about by using oxidation reduction and recording the observations‚ these tests will help determine the specific qualities each solution has. Hypothesis I theorize that nothing will happen with Magnesium because it is such a soft metal. Zinc should turn a greener color‚ because that’s what happens to a lot of statues and sculptures. I theorize that iron will tarnish badly because in air it can get tarnished so oxidation

Cobalt looks almost exactly like iron and nickel. Cobalt is between iron and nickel on the periodical table and found in only . 001-.002 percent of the earth¹s crust. Cobalt was first found in the Harz Mountains. People in the silver mines dug up arsenic cobalt ores. Then‚ because they thought the ores contained

For an example the Senate has powers to confirm Presidential nominees that they do not share with the House‚ and the House has powers to originate all tax/spending bills that are not shared with the Senate (Nickels n.d.).

During the 1960s the black society began to revolt to fight for its rights. This was caused by the change in the mentality of the younger generation of the American society. The young generation considered the blacks to hold an equal position to the whites in the society‚ and narrow the racial gap. Flannery O’Connor successfully portrays the generation gap in America during the 1960s in her short story "Everything That Rises Must Converge". Julian represents the young generation of that time‚ trying
