Many chemical reactions can be classified as one of five basic types. Having a thorough understanding of these types of reactions will be useful for predicting the products of an unknown reaction. The five basic types of chemical reactions are combination, decomposition, single-replacement, double-replacement, and combustion.

7. Swirl the flask to insure completeness of reaction. When the reaction has ceased, allow the copper product to settle. Then carefully decant the liquid from the copper, (pour off the liquid and leave the solid behind). You may observe a thin copper colored sheen on the surface of the liquid which does not settle out. You may ignore this. 8.

A precipitation reaction is when two aqueous ionic compounds form a new ionic compound that is not soluble in water. One example is the reaction between lead (II) nitrate and potassium iodide. Both compounds are white solids that can be dissolved in water to make clear, colorless solutions.
A double replacement reaction is specifically classified as a precipitation reaction when the chemical equation in question occurs in aqueous solution and one of the of the products formed is insoluble. An example of a precipitation reaction is given below: CdSO4 ( aq) + K2S ( aq) → CdS ( s) + K2SO4 ( aq) Both reactants are aqueous and one ...
Zn (s) + ½O 2 (g) → ZnO (s) ΔH⦵f = –348.3 kJ mol -1. S (s) + O 2 (g) → SO 2 (g) ΔH⦵f = –297.0 kJ mol -1. The overall reaction needs heat to get started but the heat it produces is enough to sustain the reaction thereafter. Zinc can be obtained by electrolysis of zinc sulfate or by smelting in a process similar to the production ...
