The free response section typically contained 6 to 8 "problems." Unlike today’s exam (which features long-form questions and short-answer parts), the 1972 exam required intense manual calculation. Calculators were prohibited. : Calculations involving Gibbs Free Energy ( ΔGcap

Assuming the metal has a $+3$ oxidation state (based on $M_2O_3$): $$ 2M + 6HCl \rightarrow 2MCl_3 + 3H_2 $$ Assuming the metal has a $+3$ oxidation state

Ionization energy generally increases across a period due to the increasing effective nuclear charge and decreases down a group due to the increasing distance of the outermost electron from the nucleus.
