A. a chemical formula representing a reactant

B. a chemical formula representing a product

C. a chemical symbol representing a reactant

D. a chemical symbol representing a product

you gotta add the following molecules so we can give u an answer

explanation:

by asking questions about the natural world

dipole moments occur when there is a separation of charge. they can occur between two ions in an ionic bond or between atoms in a covalent bond; dipole moments arise from differences in electronegativity. the dipole moment is a measure of the polarity of the molecule.

explanation:

in inorganic chemistry -dipole moment ( μ ) is the measure of net molecular polarity, which is the magnitude of the charge q at either end of the molecular dipole times the distance r between the charges. μ = q × r.
