8Al S 8AlS   (d) 8 2 4Al S 8AlS  
4. When two ionic compounds are dissolved in water, a double replacement reaction can
(a) Never occur since all ions in water are spectator ions
(b) Occur if two of the ions form an insoluble ionic compound, which precipitates out of solution
(c) Occur if the ions react to form a gas, which bubbles out of the solution
(d) Occur only if the ions form covalent bonds with each other.
5. Which Bronsted acid (H2O or H2
S(aq)) is the stronger acid and why is it the stronger acid?
(a) H2O is the stronger acid because oxygen has a greater electronegativity than sulfur, which gives the
attached hydrogen atom more proton character
(b) H2O is the stronger acid because H2
S is a gas and gases are not acids.
(c) H2
S is the stronger acid because the hydrogen-sulfur bond is much weaker than the hydrogen-oxygen
bond due to a greater difference in atomic orbital energy levels.
(d) H2
S is the stronger acid because it is a heavier molecule and therefore has more energetic collisions.
6. The common features among the species CN, CO, and NO are
(a) Bond order three and iso-electronic
