Which is which???

 Synthesis—when two or more different reactants combine to form one product  Example ◦ 2Mg + O 2  2MgO  Decomposition—when one reactant breaks up into two or more products  Example ◦ H 2 CO 3  CO 2 + H 2 O

 Single-replacement—a reaction in which an element reacts with a compound and replaces another element in the compound  Example ◦ Mg + 2HCl  2MgCl 2 + H 2  Double-replacement reaction—a reaction in which there is an exchange of positive ions between two compounds. These reactions generally take place between two ionic compounds.  Example ◦ Al 2 (SO 4 ) 3 + 3Ba(OH) 2  2Al(OH) 3 + 3BaSO 4

 Combustion—a reaction in which a substance reacts with oxygen, usually with the rapid release of heat and the production of a flame. Organic compounds usually burn in the oxygen in air to produce carbon dioxide and water.  Example ◦ 2 C 4 H O 2  8 CO H 2 O

 Combustion—a reaction in which a substance reacts with oxygen, usually with the rapid release of heat and the production of a flame. Organic compounds usually burn in the oxygen in air to produce carbon dioxide and water. Always the same  Example ◦ 2 C 4 H O 2  8 CO H 2 O ◦ THE PRODUCTS ARE CARBON DIOXIDE AND WATER
