Why does molecular polarity occur?
A molecule's polarity is caused when the two nuclei making up the molecule are different sizes.
Polarity is caused when electrons in a covalent bond are not equally shared.
Polarity is caused when electrons are taken by one atom in an ionic bond.
Polarity is caused when electrons are shared equally in a covalent bond.

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
