Stearic acid (C18H36O2) is a fatty acid, a molecule with a long hydrocarbon chain and an organic acid group (COOH) at the end. It is used to make cosmetics, ointments, soaps, and candles and is found in animal tissue as part of many saturated fats. In fact, when you eat meat, you are ingesting some fats containing stearic acid. ( of C18H36O2 = –948 kJ/mol, CO2=-393.5kJ/mol, H2O=-241.826kJ/mol). Calculate the heat (q) released in kcal when 3.765 g of stearic acid is burned completely.

Fatty acids are carboxylic acids with a long, unbranched hydrocarbon chain. There are three main classes of fatty acids. Classify the fatty acids as saturated, monounsaturated, or polyunsaturated. Saturated Monounsaturated Polyunsaturated linoleic acid arachidonic acid oleic acid stearic acid palmitic acid
please write clearly. thanks! 2. Stearic acid is the common name for the C18 straight-chain, saturated fatty acid. (a) Draw the structure of the fatty acyl-CoA that this forms (you don't have to draw out all of the atoms in coenzyme A; you can represent it as S-CoA), and then show all of the reactions (draw all of the compounds formed) when the eighteen carbon fat is converted to two molecules of acetyl-CoA and the fourteen-carbon fat via two turns...
