Unit Five Reactions
1. Describe chemical changes in terms of rearranging atoms to form new substances.
2. Recognize that the total number of atoms does not change during a reaction because every reactant atom must be included in a product molecule.
3. Discuss a reaction particle picture. (Describe reactions in terms of macroscopic observations and microscopic behavior of atoms.)
4. Learn to write balanced equations to represent these changes symbolically.
5. Explain that the coefficients in a chemical equation describe the quantities of the individual atoms or molecules involved.
6. Observe basic patterns in the way substances react and learn to generalize them to other reactions students encounter.
Synthesis reactions
Decomposition reactions
Combustion reactions
Single replacement reactions
Double replacement reactions
7. Represent reactions with molecular, complete ionic, and net ionic equations.
