Stearic acid (C18H36O2) is a fatty acid, a molecule with a long hydrocarbon chain and an organic acid group (COOH) at the end. I
t 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 2.831 g of stearic acid is burned completely.
Producers make food for the rest of the ecosystem through the process of photosynthesis, where the energy of the sun is used to convert carbon dioxide and water into glucose.
when sodium reacts with chlorine atoms, sodium will give an electron which is negative charged to chlorine.it makes sodium(+) and chlorine (-)..then sodium will attract chlorine to form sodium chloride(NaCl)
