The enthalpy of formation of C2H5OH is -238.7 kJ/mol. What information does this reveal about the bonds in the molecule? A. Bond Formation in C2H5OH from its elements absorbs energy.
B. Bond formation in C2H5OH from its elements does not occur.
C. Bond formation in C2H5OH from its elements releases energy.
D. Bond formation in C2H5OH from its elements only occurs in cold temperatures.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
