Answer:
Structure 1- dodecanoic acid (lauric acid)
Structure 2- hexadecanoic acid (palmitic acid)
Structure 3- octadecanoic acid (stearatic acid)
Explanation:
Fatty acids are carboxylic acids having long aliphatic chain. The chain may be either saturated or unsaturated. There are many naturally occurring fatty acids having unbranched chain of an even number of carbon atoms.
Usually, the common name of the fatty acid is not related to its systematic name. Its systematic name is obtained by IUPAC nomenclature.
The images shown are the skeletal structures of lauric acid, palmitic acid and stearic acid. I have written the names of the acids because the question specifically mentions that the compounds are fatty acids and not their salts.
Answer:
I liked the video, it gave us lots of information about___. __ means/ is about.
Explanation:
It's hard to relate a mole to carbon or sulfur. Imagine if I walked up to you and said, "What's the relation between a dozen and donuts?"
A mole is a form of measurement for atoms, more specifically, 6.02 * 10^23 atoms. I suppose you could relate it to Carbon or Sulfur, since the number of atoms of each are usually measured in moles.
Carbon and Sulfur don't have a set number of moles (Just like donuts don't have to be a dozen), so it's hard to answer your second question.
In the atomic table, the number you see under the element is the molar mass, which is the weight of an a mole of the element. In this way, I guess there's a mole of Carbon and Sulfur present, if we're looking at the periodic table.
