Unit Essential Questions
a. How do the chemicals present in a reaction help you predict the reaction type?
b. How can the periodic table help you predict bonding types?
c. How do you name and write chemical formulas?
d. Why do you need to balance equations?
Content
 Ionic or covalent bonding can be predicted by understanding the properties of the periodic table.
 There are rules for writing and naming chemical formulas using IUPAC nomenclature.
 Balancing a chemical equation is essential due to the law of conservation of matter.
 There are four types of chemical reactions: synthesis, decomposition, single displacement, and double displacement.
Key Terms/Vocabulary – “Language of the Standard/Elements”
Binary, chemical equation, chemical reaction, covalent bonding, decomposition, double replacement, ionic bonding, IUPAC

Skills
 Predict formulas for chemical reactions
 Identify four types of chemical reactions
 Balance chemical equations to satisfy the law of conservation of matter
Assessment(s)
Performance tasks
Lab: Types of equations lab. Students complete 4 different lab stations and write balanced equations for the reactions, as well
as classifying the type of reaction they observed. They must provide evidence of what they observed.
Balancing equation lab: Students will use manipulatives to represent different elements in order to visualize the law of
conservation of matter being satisfied. After they have balanced the equations, they need to classify the reaction.
Quizzes: Vocabulary, quiz over polyatomic ions
Guided practice: flow chart for writing formulas, graphic organizer for ionic/covalent bonds;
worksheets on writing formulas, naming compounds, balancing and classifying
