Activity 1: Types of Chemical Reactions 1
Instructions
As you read through the lesson online, use the space below to take notes.
In this laboratory, you will study different kinds of chemical reactions.
Knowing the types of reactions helps you interpret your observations.
In a synthesis reaction, two reactants unite to form a third product.
In a single-displacement reaction, one ion of a reactant bonds with the second reactant.
In a double-displacement reaction, ions of both reactants change places.
