In the mixture lab, benzoic acid was mainly monitored near:

When operating the UV-Vis, what is the main difference between the Fixed Wavelength and Spectrum/Peaks task modes?

Which component in the UV-Vis actually separates the light into individual wavelengths?

In gas chromatography if you are analyzing a sample and your peaks are not visible or are merged into one massive peak what could you do to correct this? (Select ALL that apply.)

A Beer’s law plot with R² = 0.999 tells you:

Which of the following are correct UV-Vis cuvette practices emphasized in the KMnO₄ and instrument labs? (Select all that apply)

In UV-Vis spectroscopy, the Fixed Wavelength task measures sample data at up to [A] different wavelengths and can display results as absorbance, transmittance, or derivative values, while the Spectrum/Peaks task focuses on the [B] scale to locate absorbance maxima and minima.

For the mixture lab, it would have been acceptable to use dark, highly colored sodas with the same method.

In the KMnO₄ experiment, a blank containing just distilled water is appropriate.
