Isomers, such as acetic acid and methyl formate, have A. different empirical formulas.
B. the same chemical formula, arrangement of bonds, and orientation of atoms.
C. the same chemical formula but different arrangements of bonds or atoms.
D. different chemical formulas.

the answer is C given by the definition of isomer compounds

a small container that holds a source of energy a solar cell that captures light energy and converts it into electricity a voltaic cell that uses the oxidation of a fuel to produce electricity

explanation:

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
