This part of the experiment yielded an exothermic reaction. The purpose was to calculate the specific heat capacity and molar mass of the zinc metal. The specific heat capacity was found to be 0.197 J/g °C with a percent error of -49.5%. The molar mass was found to be 127 g/mol with a percent error of 94.2%. Possible sources of error inherent to this segment of the experiment were the fact that when the temperature of the solution was being measured

How Malcolm X found his enlightenment. Enlightenment is the act or a means of enlightening (to give intellectual or spiritual light to; impart knowledge to). It’s also a philosophical movement of the 18th century that emphasized the use of reason to scrutinize previously accepted doctrines and traditions and that brought about many humanitarian reforms. The "Allegory of the Cave" by Plato represents an extended metaphor that is to contrast the way in which we perceive and believe in what is reality

In this article "Airport Screeners Could See X-rated X-ray’s" Joe Sharkey tells us a little bit about a new airline security program. Sharkey advertizes that airlines are trying to bring in X-ray units that will be able to look beyond clothing‚ to the outline of bare skin. This precaution is becoming effective because technology is getting more advanced. Since metal detectors can’t be as reliable as we once thought‚ serious measures need to be demanded. However‚ scientists have discovered the previous

The milgram experiment. The three people involved were: the one running the experiment‚ the subject of the experiment a volunteer‚ and a person pretending to be a volunteer. These three persons fill three distinct roles: the Experimenter an authoritative role‚ the Teacher a role intended to obey the orders of the Experimenter‚ and the Learner the recipient of stimulus from the Teacher. The subject and the actor both drew slips of paper to determine their roles‚ but unknown to the subject‚ both slips

Today I am going to talk about the one and only Malcolm X. I asked many people who they thought Malcolm X was and none of them knew. They were saying that he was a boxer‚ a black dude‚ or a random guy who was celebrated. But little did they know that he was kind of like Martin Luther King except that he believed in taking
