Sodium-22 undergoes electron capture. Identify the resulting isotope.

Uranium-235 decays by alpha emission. What isotope is also produced by this transformation?

Which of the following aqueous solutions will have the highest boiling point?

The rate constant for the second order reaction 3A → 4B is 6.00 × 10–3 M–1 min–1. How long will it take the concentration of A to drop from 0.75 M to 0.25 M?  

The 14C activity of an artifact has 10 disintegrations per minute per gram of carbon. If present-day plant life shows 15 dpm/g, how old is artifact? (The half-life of 14C is 5730 yr).  

Use the standard half-cell potentials listed below to calculate the standard cell potential for a galvanic cell at 25°C made from those materials.  Mg2+(aq) + 2 e⁻ → Mg(s) E° = -2.38 V Cu2+(aq) + 2 e⁻ → Cu(s) E° = +0.34 V
