Identities of the components in a mixture may be determined by a technique called spiking. Suppose you had run a gas chromatogram on your product and had then deliberately added a drop of a known sample of 3-methylcyclohexene to a drop of your product. What would you expect the new chromatogram to show you?

Question
**Text Transcription:** Identities of the components in a mixture may be determined by a technique called *spiking*. Suppose you had run a gas chromatogram on your product and had then deliberately added a drop of a known sample of 3-methylcyclohexene to a drop of your product. What would you expect the new chromatogram to show you? --- **Explanation for Educational Context:** In this passage, the concept of *spiking* is introduced as a method for identifying components in a chemical mixture. Spiking involves adding a known substance, in this case, 3-methylcyclohexene, into the mixture to see how it affects the chromatogram. A gas chromatogram is a graph used to analyze the composition of a chemical sample by separating its components. When you add or "spike" a known sample to the mixture and run a new chromatogram, you would typically expect to see an increase or change in the peak corresponding to that substance, confirming its presence in the mixture. This technique helps distinguish specific substances by comparing the chromatograms before and after spiking.
