Net ionic equations using solubility rules that become precipitates

Use the Solubility Rules to write net ionic equations for the reactions that occur when solutions of the following are mixed. Instructions 1. Write reactants and products in the following order: Cation + Anion = Precipitate 2. Use "->" (hyphen + greater than) to indicate 'yields' 3. Write subscripts as numbers with no ...continues

Calculation of bond energies and enthalpies.

You may wish to review the Laws of Thermochemistry and Endothermic and Exothermic Reactions before you begin. A table of single bond energies should be used as a help (available in most general chemistry text books). Estimate the change in enthalpy, DH, for the following reaction: H2(g) + Cl2(g) --> 2 HCl(g)
