There is an unlabeled vial of clear, colorless liquid in your lab drawer and you need to decide whether the vial contains cyclohexene or cyclohexanol. Describe three methods of analysis or tests and the expected results that could help you decide the identity of this liquid.

A student was given a 10 mL sample of a clear, colorless liquid. She was assigned the task of identifying the unknown liquid and was told that the sample could be methanol (CH_3OH), acetone (C_3H_6O), or ethanol (C_2H_5OH). She decided to attempt to determine the molar mass of the liquid by the vapor density method, which involves completely vaporizing a small sample of the liquid, cooling it and determining the mass of the condensed vapor. She also collects the volume...

You are given three boxes filled with chocolates. One box contains only dark chocolates, one box contains only milk chocolates, and one contains both dark and milk chocolates. However, the boxes are labeled incorrectly. You know that you have exactly one box of each, and you also know that each box is definitely labeled wrong. Given the incorrect labeling of the chocolate boxes and the three observations, use Propositional Logic to derive the correct labeling of the second box. You...

In our experiment we will use three different substrates: 1°,
n-butyl chloride; 2°, sec-butyl chloride; and 3°, tert- butyl
chloride, and we will evaluate their reactivity and the rate of the
reaction in an SN1 reaction. We will use an acid-base indicator to
monitor the completion of the reaction and a salt, silver nitrate,
to obtain a precipitate. The success of the reaction is evidenced
by the change in color of the indicator (from orange to red) due to
the...

You have a stock 4.00 times 10^-4 solution of KMnO_4, and three 50.00ml volumetric flasks. Each contains 40.00ml, 20.00ml and 10.00ml of the stock solution, respectively. Each flask contains respectively. Each is diluted to the mark with water. After the solutions were well mixed, each was analyzed by the use of spectrophotometer using a 1.00-cm cuvette. The results are presented in the table below. Make a Beer's Law plot and determine the extinction coefficient (with units), as well as the...

You have three genes on the same chromosome - A, B and C. Each gene has two alleles in a dominant/recessive relationship. For these genes the homozygous recessive has the mutant phenotype for that trait, the dominant phenotype = wild type for that trait. allele A is dominant to a; phenotype a = mutant for trait a; phenotype A = wild type for trait A allele B is dominant to b; phenotype b = mutant for trait b; phenotype B...
