Chapter 8 - Section 8-2: Types of Reactions There are five major types of chemical reactions. They are synthesis, decomposition, single replacement, double replacement, and combustion. Being able to recognize what type of reaction is occurring will help you predict the products. Synthesis What is a Synthesis Reaction? In a synthesis reaction, two or more substances – either elements or compounds – combine to form one new compound. The general equation for a synthesis reaction is: A + X AX A and X can be elements or compounds, AX is a compound Types of Synthesis Reactions 1. Reactions of Elements with Oxygen and Sulfur: A) Metal + Oxygen gas Metallic Oxide Example: Magnesium metal combines with oxygen gas B) Metal + Sulfur Metallic Sulfide Example: solid rubidium combines with sulfur 2. Reactions of Metals with Halogens A) Metal + Halogen Binary Ionic Compound Example: Magnesium metal reacts with fluorine gas 3. Reactions with Oxides A) Metallic oxide + Water → Metallic Hydroxide (base)
