Document Summary

Calculate q for the water: the acid-base neutralization reaction releases energy: H3o+ (aq) + oh- (aq) 2 h2o (l) Calculate the energy change when 25. 0 ml of 0. 100 m hcl reacts with excess aqueous naoh: water forms beads on the surface of a freshly waxed automobile, but it forms a film on the clean windshield. Answer: wax contains hydrocarbon molecules that cannot form hydrogen bonds to water molecules, so water forms beads on a freshly waxed surface. Answer: the vapour pressure of a substance at any given temperature is determined by the strength of intermolecular forces: the stronger the forces, the lower the vapour pressure. (a) Answer: the position of an element in the periodic table, the chemical formula, and knowledge of polyatomic ions all help in identifying types of solids: 3- polyatomic anions, so it is an ionic solid. + cations and po4: solid silver adopts a fcc.
