This figure shows the interaction of a cation with surrounding water molecules.
(a) Which atom of water is associated with the cation? Explain.
(b) Which of the following explanations accounts for the fact that the ion-solvent interaction is greater for Li+ than for K+?
a. Li+ is of lower mass than K+.
b. The ionization energy of Li is higher than that for K.
c. Li+ has a smaller ionic radius than K+.
Chemistry: February 8-12 Law of Conservation of Mass • the same number of each atom much be in the reactants and products of a chemical reaction • balancing equations (either by ‘guess and check’ or by using variables) *there is a set of practice equations on D2L to work out o example used in class: Nomenclature • Basics of naming compounds (unless hydrogen is present): o cations (metal) are named first o anions (nonmetals) are named after and the ending changes to “-ide” • Acids: o if anion ends in “-ide”, then it is said as “hydro-stem-ic acid” § example of ‘stem’: chlor § example: HCl= hydrochloric acid o i
