Introduction
These are elements or compounds that are present before a chemical reaction takes place.
What are reactants?
This covalent compound has the formula CO2.
What is carbon dioxide?
This is the coefficient in this formula: 3H2O
What is 3?
This is the reason why we balance chemical equations.

*whiteboard required*
Balance the chemical equation and identify what type of reaction this is: Ga + Br2 --> GaBr3
What is 2Ga + 3Br2 --> 2GaBr3?
Synthesis
This happens to chemical bonds during a chemical reaction.
What is bond formation and breaking?
When a metal bonds with a nonmetal, this compound is most likely to form.
What is an ionic compound?
This is the subscript for sulfur in this formula: Na2SO4
What is 1?
This is what the law of conservation of mass says.
What is "mass cannot be created or destroyed, only changed in form"?

Balance the chemical equation:
Be + FeCl3 --> BeCl2 + FeCl2
What is Be + 2FeCl3 --> 2FeCl2 + BeCl2?
This refers to a solid state product that forms when two reactants dissolved in water are mixed.
What is a precipitate?
*Daily Double*
When the anion of a ionic compound is monatomic, the ending of the ion is changed to this.
