An oxygen o2 molecule is adsorbed on a patch of surface (see sketch at right). this patch is known to contain 484 adsorption sites. the o2 molecule has enough energy to move from site to site, so it could be on any one of them. suppose additional surface becomes exposed, so that 729 adsorption sites are now available for the molecule. calculate the change in entropy. round your answer to 3 significant digits, and be sure it has the correct unit symbol.

The picture represents the process that produces most of the energy used by living organisms on earth. which process is represented in the picture? a) the magnetic attraction between two hydrogen nuclei. b) the fusion of hydrogen nuclei to produce a helium nucleus in the core of the sun. c) the fission of hydrogen nuclei to produce a helium nucleus in the core of the sun. d) the chemical reaction between hydrogen nuclei to produce a helium nucleus in earth's atmosphere.
