At 25°C, the standard enthalpy of formation of anhydrous sodium carbonate is –1130.9 kJ/mol, whereas the standard enthalpy of formation of sodium carbonate monohydrate is –1430.1 kJ/mol.  Determine ΔH° at 25°C for the reaction
         Na2CO3(s) + H2O(l) → Na2CO3·H2O(s).
(Given:  ΔH°f[H2O(l)] = –285.8 kJ/mol)
◦ –585.0 kJ/mol
◦ –299.2 kJ/mol
◦ –285.8 kJ/mol
◦ –156.3 kJ/mol
◦ –13.4 kJ/mol

IgA antibodies protect body surfaces exposed to outside foreign substances. IgG antibodies are found in all body fluids. IgM antibodies are the first type of antibody made in response to an infection. IgE antibody levels are often high in people with allergies. IgD antibodies are found in tissues lining the abdomen and chest.

Your skin wrinkles if you stay in the bathtub a long time because the outermost layer of skin (which consists of dead keratin) swells when it absorbs water. It is tightly attached to the skin below it, so it compensates for the increased area by wrinkling. This happens to the hands and feet because they have the thickest layer of dead keratin cells.
