McLean 1 Creating Acetylene Gas Introduction The purpose of the lab was to determine the ratio of air to acetylene results in complete combustion of acetylene gas. The balanced chemical equation for this experiment was C2H2(g) + O2(g) --> CO2(g)+ H2O(l). Complete combustion is the reaction of an element or compound with oxygen to produce the most common oxides and energy. Complete combustion occurs when the fuel and oxygen combine in exact proportions to completely burn the fuel

Multimedia Graphic Bell Labs: A Hive of Invention But we idealize America’s present culture of innovation too much. In fact‚ our trailblazing digital firms may not be the hothouse environments for creativity we might think. I find myself arriving at these doubts after spending five years looking at the innovative process at Bell Labs‚ the onetime research and development organization of the country’s formerly monopolistic telephone company‚ AT&T. Why study Bell Labs? It offers a number of lessons

African Diaspora and the World After reading the short story “Diaspora” by Joanne Hyppolite‚ I got a vivid understanding of how diaspora can have an effect on one’s identity. Over the past month we have studied many theories and concepts concerning race‚ gender‚ and politics. There are three theories that capture the essence of Joanne Hyppolite’s worldview as a Haitian growing up in America: intersectionality‚ identity‚ and diaspora. Individuals oftentimes experience the theory of Intersectionality

PROBABILITY and MENDELIAN GENETICS LAB Hypothesis: If we toss the coin(s) for many times‚ then we will have more chances to reach the prediction that we expect based on the principle of probability. Results: As for part 1: probability of the occurrence of a single event‚ the deviation of heads and tails of 20 tosses is zero‚ which means that the possibility of heads and tails is ten to ten‚ which means equally chances. The deviation of heads and tails of 30 tosses is 4‚ which means that the

3.2 “Lab-on-a-Chip” A Lab-on-a-Chip (LOC) device‚ also known as a micro-total-analytical system (microTAS) or microfluidics device‚ is a device that can integrate miniaturized laboratory functions (such as separation and analysis of components of a mixture) on a single microprocessor chip using extremely small fluid volumes on the order of nanoliters to picoliters. From a technology categorization perspective‚ LOCs can be viewed as a subset of microelectromechanical systems (MEMS) and combine
