2. What is the driving force for the reaction described in Q1 above?

The formation of a new insoluble ionic compound

The formation of a gas

the formation of water molecules

the formation of new ions

the formation of a new soluble ionic compound

3. Write out the balanced molecular equation and ionic equation for the overall reaction from Q1 when the 2 solutions are mixed. Then draw a picture diagraming what the beaker will look like (similar to what we have done in class) after the reaction is complete. Represent the soluble ions and insoluble ionic compounds.

    In many chemical reactions of two or more compounds, ions are present in the solution that do not participate in the reaction. These ions, known as spectator ions, can be removed from the chemical equation describing the reaction. A chemical equation that has the spectator ions removed is known as a net ionic equation. Reactions between ionic compounds often result in the precipitation of an insoluble compound. Spectator ions and precipitation products of a chemical reaction can be predicted by...
