Assume that 13.5 g solid aluminum (Al) react with HCl to produce solid aluminum chloride (AlCl3) salt and gaseous hydrogen (H2) at standard temperature and pressure.

What is the maximum number of hydrogen bonds that can be formed in a sample containing 1.0 mol (NÅ molecules) liquid HF? Compare with the maximum number that can form in 1.0 mol liquid water.

Based on reactivity, which of the following elements can replace aluminum (Al) in a compound during a single replacement reaction?
