Experiment D-Pre-lab: Synthesis of a Room Temperature Ionic Liquid (RTIL) Name: Morgan Smith Student #:130635880 Date Submitted: November 7‚ 2014 Lab Section: Friday 2:30pm‚ Section 9 T.A: Matt Halloran 1. Refer to the last page. 2. Arrow pushing mechanism: 3. Refluxing is when the reactants are boiled and the vapor that is produced is cooled. When the vapor is cooled it changes back to its liquid state and returns to the flask. 4. The visual cue that allows you to determine that the

River Road. To gauge whether or not traffic control is necessary‚ vehicles are timed at a specific interval to give a range of varying speeds; these speeds could then be compared to the set speed limit on the road. The purpose of this experiment was to determine if cars on Woody Hayes Drive needed additional traffic control to reduce speeding. The sections that follow describe the process‚ calculations and answers to this experiment. Section 2 will describe the tools and step-by-step processes that’re

Liza Handler Experiment Background: Squid is a keystone species‚ negative effects on them can have major consequences down the line. Nearly all of the animals in the oceans ecosystems either eat squid‚ or are eaten by squid. Squids not only have a vital role in our Oceans ecological community‚ but they also are important economically. Squid is a main source of food for the tuna and hake‚ two major commercially important fish. In 2011‚ fisherman harvested a total of $100 million worth of squid

The purpose of this lab was to determine if a there is a change in mass when a gas is produced and determine if gas has mass. To conduct this experiment‚ the group must be careful not to let the Alka-Seltzer tablet get wet before the bottle is closed by wiping the lip of the bottle and the cap so it remains dry‚ or risk gas escaping into the air and not being captured by the bottle. Also‚ the group must be sure to close the bottle tightly with the cap‚ because gas may escape this way as well. During

into a petri-dish and the cylinder removed and blotted with filter paper‚ throwing the liquid away from the petri-dish after each cylinder was removed. 7) The length and texture of each potato cylinder was recorded in a table. Discussion: In the experiment‚ I believe the phenomenon to take place is osmosis. Osmosis is the movement/diffusion of water molecules through a selectively permeable membrane from an area of high concentration of water molecules (high water potential) to an area of a low concentration

Tuskegee Syphilis experiment is the most infamous clinical study conducted in the United States between 1932 -1972. The study of natural progression of untreated syphilis in rural Africa American men‚ led to a forty year study which was controversial for reasons related to ethical standards; researchers knowingly failed to treat patients after the 1940s validation of penicillin. The patients with syphilis were never told they had it‚ were part of a case study‚ could leave the experiment at any given

Experiment 4A – Counting Atoms in a Chemical Reaction Purpose: The purpose of this lab is to create an experiment where zinc reacts with hydrochloric acid in order to find out the number of moles and atoms of zinc reacted. This can be accomplished by weighing the sample before and after the reaction with hydrochloric acid. Data: Material Mass in grams (g) Initial mass of dry beaker 49.37 Initial mass of dry beaker + zinc 51.03 Initial mass of zinc 1.66 Final mass
