Answer:
1. Option C Â The net ionic equation shows only the substances that change in the reaction.
2. Option B Â (s)
3. Option B Â decomposition and single-displacement
Explanation:
1. The net ionic equation only shows the substances that are reacting. the net ionic equation removes the spectator ions. These are ions that do not really have a big part in the reaction.
2.  A precipitate is a solid product that is formed as a result of reaction of two acqeous  substances.  This is symbolized by the symbol (s) for solid.
3. Â A decomposition reaction takes place when one compound is decomposed into two of its reactants. An example is hydrogen peroxide, which decomposes like this:
Hâ‚‚Oâ‚‚ (g) = Hâ‚‚ (g) + Oâ‚‚ (g)
