When KCl dissolves in water: the Cl- ions are attracted to the partially negative oxygen atoms of the water molecule.

the K+ ions are attracted to Cl- ions on the KCl crystal.

the K+ ions are attracted to the partially positive hydrogen atoms of the water molecule.

the K+ ions are attracted to the partially negative oxygen atoms of the water molecule.

the Cl- ions are attracted to dissolved K+ ions.

Asolution contains 180 g of glucose (c6h12o6) and 162 g of water. what is the mole fraction of glucose?

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?
