are there other tests that could be used to determine if cyclohexanol is present in your product? give at least one test with so
Artist 52 [7]

One of the many tests that may be used to identify the presence of cyclohexanol in a product is that of the Lucas test.

The Lucas test is a chemical reactant test to determine the presence and level of alcoholism in a solution.  Cyclohexanol has many chemical properties as do most substances, one of which is the presence of an alcohol group.

The presence of this chemical group makes it possible to test for cyclohexanol using the Lucas test. The Lucas test will cause reactions in the presence of alcohol and transform alcohols into chloroalkanes, which tend to be nearly insoluble in aquatic solutions. Given this, a <u>positive result </u>will look like <em><u>the solution separates into a cloudy chloroalkane-containing part on top of a much clearer layer.</u></em>

How are mean and median alike?how are they different?
Vlada [557]

Answer:

Mean is the average you'll get when you add all your numbers then divide by the number of numbers you have. On the opposite side, median is the middle number within your list of numbers. If there isn't a middle number, take the two middle numbers and add them. Now, for how they are alike, I'm not so sure :'), but my closest guess would be they are fairly close together.

Sorry it's so long, hope I helped you :')
