In order to determine the calories in a food sample, a chemist prepares their calorimeter with 100ml of water. The chemist took an initial temperature of 22 degrees celsius. After the food source burned the chemist then determined the the final temperature was 42 degrees celsius. What was the change of temperature of the water?

the answer is c i took the test

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.
