One of the main ideas of the quantum theory is that:

the energy of an electron can never be changed

the energy of an electron can be varied by any amount

the energy of an electron can be changed only by set amounts

the energy of an electron can always be predicted with 100% accuracy

the energy of an electron can be changed by only set amounts

fe 55.85 g/mol and h2o 18.02 g/mol.

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".
