The distance that light travels in one year is approximately 9,460,000,000,000 kilometers. In scientific notation, this would be expressed as: 9.46 x 10^?

Describe how you could use IR spectroscopy to distinguish between ethyl acetate and butyric acid. The IR spectrum of butyric acid should have a broad signal between 1650 cm-1 and 1850 cm-1. An IR spectrum of ethyl acetate will not have this signal.
