A student investigates the enthalpy of solution, $\Delta H_{\text {soln }}$ , for two alkali metal halides, LiCl and NaCl. In addition to the salts, the student has access to a calorimeter, a balance with a precision of ±0.1 g, and a thermometer with a precision of ±0.1°C.

Below is a representation of a portion of a crystal of LiCl. Identify the ions in the representation by writing the appropriate formulas ( $\mathrm{Li}^{+}$ or $\mathrm{Cl}^{-}$ ) in the boxes below.
