Water (H2O) is made up of molecules with a bent structure, whereas hydrogen sulfide (H2S) is also made up of molecules with a bent structure. Why is the melting point of H2O much higher than the melting point of H2S? Select all correct answers. a. The intermolecular forces in H2S are much greater than those in H2O
b. The intermolecular forces in H2O are much greater than those in H2S
c. The three-dimensional arrangement of water makes it a polar molecule
d. Hydrogen sulfide has a lower molar mass than water

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?
