"In this experiment you will observe chemical bonding by making mayonnaise – and yes, you will be able to eat it when you are finished. The vinegar is a compound with polar bonds, whereas the oil has non-polar bonds. Normally the two will not mix. However, the lecithin in the egg yolk acts like a detergent and allows the two to mix together."
This is about chemical bonding. But other than that was I suppose to understand something else. Because I can't answer this question.
1. If you were given a piece of hot dog and a piece of carrot, using what you learned in this exercise, how would you analyze the composition of these materials?

You learned:
1. polar compounds do not mix with non-polar compounds
2. detergents allow them to mix together
To answer the question:
If you stick a hot dog in water(polar), you will see the oil(non-polar) float on top. You now know that hot dog has oil on it. If you mush up the hot dog, stick it in a graduated cylinder with water in it, you can actually measure how much oil by volume there was.
If you stick the carrot in water, you will not see any oil float up. You now know that carrots do not have a lot of oil. Carrots do have some fat though, and if you mush it up, you can find out how much fat there is.
Alternately, you can stick them in oil and then measure how much water was in them.
