  \question When cesium metal is exposed to chlorine gas, a bright flash occurs as the elements react. The product, cesium chloride, is a white solid composed of cesium ions and chloride ions.
  \begin{parts}
    \part Write the balanced overall reaction which occurs between chlorine and cesium.
    \vspace{2in}
    \part Write the half-reactions which occur and identify which half-reaction is the reduction and which is the oxidation.
