Stearic acid (C18H36O2) is a typical fatty acid, a molecule with a long hydrocarbon
Chapter 6, Problem 6.82(choose chapter or problem)
Stearic acid (C18H36O2) is a typical 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, chances are that you are ingesting some fats that contain stearic acid. (a) Write a balanced equation for the complete combustion of stearic acid to gaseous products. (b) Calculate _H_rxn for this combustion (_H_f of C18H36O2 _ _948 kJ/mol). (c) Calculate the heat (q) in kJ and kcal when 1.00 g of stearic acid is burned completely. (d) Nutritional information for a candy bar states that one serving contains 11.0 g of fat and 100. Cal from fat (1 Cal _ 1 kcal). Is this information consistent with your answer for (c)?
