When 481 J of energy is added to 18.3 g of aluminum at 17.4°C, the temperature increases
to 46.6°C. What is the specific heat of aluminum?

catya your not at all which answer i've seen you do this on another question!

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.
