Question 1

If a constant current of 4.5 amperes is passed through a cell containing Cr3+ for 1.0 hour, how many grams of Cr will plate out onto the cathode? (The atomic mass of Cr is 51.996.)

◦ 8.7 g
◦ 8.1 × 10–4 g
◦ 2.9 g
◦ 26 g
◦ 5.6 × 10–2 g

Question 2

If a reducing agent M reacts with an oxidizing agent N+ to give M+ and N, and the equilibrium constant for the reaction is 1.9, then what is the E° value for the oxidation-reduction reaction?

◦ 0.016 V
◦ –0.016 V
◦ 0.0082 V
◦ –0.0082 V
◦ 0.033 V

The use of salicylates dates back 2,500 years to Hippocrates’s recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.
