mixture melting point of a mixture of the two pure compounds. c) Identify an unknown organic compound by determining its melting point and mixture melting point. Procedure and Observations: Using the procedure outlined in Appendix A of the Lab Manual‚ approximately equal samples of p-Nitrophenol and acetanilide‚ which are known to have the same melting range of 113-114 degrees Celcius‚ were taken and inserted into the melting point apparatus. The melting points of the compounds were noted

b 1 Exercise 1: Dissolved oxygen is oxygen that is trapped in a fluid‚ such as water. Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally

"The Fronde" The Fronde was a period of uncertainty in France. A time in which a newly crowned king of just ten years old at the time. A young king named Louis XIV was chased by the upper middle class and the nobility and treated as prisoners. These two social groups required some change in their government. They desired less powering the hand of the king and more toward the people’s hands. However‚ everyone knows that this contradicts what Louis XIV desired for France; an absolute monarchy. One

Experiment 1 Cyanobacteria Oxygen Production Through Photosynthesis Date Performed: September 2‚ 2014 I. Introduction a. Background Cyanobacteria or blue green algae are renowned for their tolerability and susceptibility even in wide range of environmental conditions‚ a characteristic of many primitive organisms. CNB are believed to be the agents of autotrophic origin of life thus they probably represent the survivors of the earliest photosynthetic plants‚ along with photosynthetic and chemosynthetic

Lab Questions By Zackary Conte and Justin Dvorsak The first experiment with 1 M sucrose in the bag and distilled water in the beaker had almost exactly the same results. The masses were relatively the same the difference have could been from the amount of liquid that was placed inside of each of the bags. The second experiment with 5% Ovalbumin in the bag and 1 M sucrose in the beaker had almost exactly the same results. The masses were relatively the same the difference could have been from the
