Determining the Percent Copper and Zinc in Pennies from Density Lab Report Procedure: For pre-1982 pennies- Mass 10 pennies‚ record data. Fill a 100mL graduated cylinder to 40mL or enough to fully submerge the pennies with water‚ record the volume in data table. Carefully place the pennies into the graduated cylinder‚ record the final volume of the water in data table. To find the volume of the pennies‚ subtract the final volume from the initial‚ record the data. Repeat this procedure twice more

concentration camps‚ where their best option was living and working in terrible conditions‚ and their worst option death. My question is why did this devastating genocide occur? Looking back‚ the holocaust was a horrible event in human history yet years after the event‚ even with the treaties that resulted‚ genocide would occur again in several instances. In my paper I will give a detailed history of the political/environmental conditions that

The main problem with relativism is that what is good and what is bad can always change depending on the person so you can never reach a final answer. There are also arguments where absolutes are necessary. Some people believe that relativism does give a convincing argument why people should be good. Relativism

Hydrogen peroxide and iodide ions Aim: To determine the rate equation for the reaction between Hydrogen peroxide and iodide ions‚ and to investigate the effects of a catalyst and temperatures on the reaction and to derive the activation enthalpy. Background knowledge: 1Hydrogen peroxide reacts with iodide ions producing iodine‚ when in an aqueous acid solution. H2O2 (aq) + 2I- (aq) + 2H3O+(aq) I2 (aq) + 2H2O(l) To detect iodine you can look at the color shown by the addition of starch

Stanley Milgram Experiment The video I watched was a reenactment of the original Stanley Milgram experiment conducted by Derren Brown. In the experiment‚ the subjects were told that they were doing an experiment on how punishment could affect learning. They were tricked into thinking that they picked their own roles when they actually got the teacher roles and the actor got the learner role on purpose. They started the experiment by showing them what they were going to do to the “learner”. They were

What Happened In 1977 Jonestown was founded for members of the people’s temple by Jim Jones in the jungles of Guyana‚ and had 50 people living there. This all changed when an exposé was being printed about him. The article included article with ex-members.

What am I eating? Food is one of the great blessing by God for all his creation. We need food and water to be alive. From the beginning of the world the demand of the food is increasing day by day. The global food chain was already quite extensive by 1701- to the point where affluent English consumers could be oblivious to the costs of sweetening their tea and peppering their sausage.
