Indicate what error the experimenter made when running the following TLCs.
Consider the following errors that could be made when running TLC. Indicate what should be done to correct the error. A two-component mixture containing 1-octene and 1, 4-dimethylbenzene gave only one spot with an Rf value of 0.95. The solvent used was acetone. A two-component mixture containing a dicarboxylic acid and tricarboxylic acid gave only one spot with an Rf value of 0.05. The solvent used was hexane. When a TLC plate was developed, the solvent front ran off the...

The bookkeeper for Birmingham Corporation made these errors in journalizing and posting. For each error, indicate whether the trial balance will balance; if the trial balance will not balance, indicate the amount of the difference, and the trial balance column that will have the larger total. Consider each error separately. Use the following form, in which error 1 is given as an example. Error In Balance Difference Larger Column 1. No $400 Debit 2. Yes $ 0 None 3. Yes...

Suppose that you are the experimenter of a project running several sections of both the experimental group and control group. The sections will be run on Thursday afternoon and Friday morning. The two rooms you have been assigned vary from each other: one has neutral paint on the walls; the other has bright orange psychedelic paint. How can physical effects be minimized as potential confounding influences in this study?
A _experiment is used when both the participant and the experimenter are uninformed about what condition the participant is actually in.
