FUNCTIONAL GROUPS IDENTIFICATION LAB Professor Burton decided to select two unknowns from Group 1 (299 & 399) and two unknowns from Group 2 (499 & 699). Below are the descriptions of his observations/results for each unknown. UNKNOWN #: 299 2,4-dinitrophenyl hydrazine Test: solution remains colorless Fehling’s Test: solution remains colorless Lucas test: observed solution in 5-min intervals for 20 min., the solution remains colorless Tollen’s test: solution remains colorless Iodoform Test: solution remains colorless Bordwell-Wellman Test: solution became quite...

In this section of the laboratory, we will investigate different types of collisions between carts using a force sensor to measure the forces during the collisions. Collisions will include a large number of different situations varying the masses of the two carts, the cart speeds, and also the cart directions. Watch the following movie which shows a demonstration of Newton’s 3rd Law with the motion carts. https://www.youtube.com/watch?v=4NHWQsNw0i4&feature=youtu.be What can you conclude about the forces involved in the collision? Does it...
1. How can/do YOU reduce the amount of waste and pollution that you create? In other words, describe 3 things that you can do/already do to reduce, reuse and recycle more. 2. The City of Phoenix recently started a program called "Save as You Reduce and Recycle", in which families are charged less for waste services (i.e., removal of their solid waste) if they opt to have a smaller trash can, as shown in the first video below. ( You...

answer 1-4 Polymers are large molecules that exist in chains composed of smaller repeating units called monomers. They can come in many forms according to substitution patterns and functional groups. Linear polymers have the monomers repeated in just one line. Cross-linked polymers are branched. Linear polymers have just two ends. Cross-linked have more than two ends. If more than two functional groups (reactive sites) are present in the monomer, the monomers may connect to each other by cross-linking to form...
