This document discusses the five main types of chemical reactions: decomposition reactions, where a single compound breaks down into simpler substances; synthesis reactions, where two or more reactants combine to form a single new compound; single replacement reactions, where an element replaces another in a compound; double replacement reactions, where ions in two reactants switch places to form two new compounds; and combustion reactions, where a substance reacts with oxygen to produce heat and light. It provides examples of each type and asks questions to test understanding.
23. QUESTIONS
1. What is an example of a decomposition reaction?
2. What type of reaction is this: X + Y XY
3. In what type of reaction do the reactants break apart?
4. What type of reaction is this: XY + Z XZ + Y
5. In what type of reaction do two compounds switch ions
with each other?
6. What kind of reaction do
you think made this rust in
the picture? (Hint: rust is
usually iron oxide = Fe2O3)
