4. Recap - Last Friday’s stuff
Quiz – Balancing Equations
Collected Balancing Equations worksheets I and II with reactions classified.

5. Types of Reactions (11.2) 1) Combination (Synthesis) 2) Decomposition
3) Single Replacement
4) Double Replacement
5) Combustion

6. Classwork (in notebook)
Pg. 339 #24
Pg. 347 #51 (remember the reactants and products for combustion reactions)
Pg. 347 #52

7. Writing chemical equations
Chemical reaction – one or more reactants change into one or more products.
Reactant – The substances that react in a chemical reaction.
Product – The substances that are produced in a chemical reaction

8. Reactants  Products Writing Word Equations
Iron reacts with oxygen to produce iron(III) oxide
Iron + Oxygen  Iron (III) oxide
Fe + O2  Fe2O3

9. The arrow () represents the change.
Writing Word Equations
The arrow () represents the change.
Yields
Produces
Gives off
Makes
Forms
Breaks down

10. Things to remember/note
1) Do you name using molecular or ionic naming system?
2) Most transition metals need a roman numeral to represent charge.
3) Check the polyatomic ion chart on pg. 257 for help.
4) Did you use the correct transition words?
5) Elements by themselves are just the element name.

11. Practice How would you write the following into a chemical equation?
Sodium combines with chlorine to produce sodium chloride.
Solid iron(III) oxide and carbon monoxide gas produce iron metal and carbon dioxide gas.

12. What would sentences for the following equations look like?
Practice
What would sentences for the following equations look like?
Na2O + H2O  NaOH
CS2 + O2  CO2 + SO2

13. Practice
Based on classwork/homework from yesterday, write sentences to represent the chemical equations.
