Brief Summary of Unit
Students will understand that:
• Molecules react in specific patterns (synthesis, decomposition, combustion, single-displacement, and double-displacement)
• The balancing of chemical equations exemplifies the Law of Conservation of Mass.
• Evidences needed to determine if there is a chemical reaction.
• Reactants and Products should be equal in a balanced chemical equation
• How do chemical reactions satisfy the Law of Conservation of Matter?
• How are the different types of chemical reactions classified?
• Why do you need to balance equations?
• How does matter being recycles and a nuclear bomb both prove the law of conservation of mass?
Students will know: (Knowledge)
• In a chemical reaction matter is not created or destroyed but is conserved.
• In a synthesis reaction two or more substances combine to form another substance.
• A decomposition reaction occurs when one substance breaks down or decomposes into two or more substances.
• Single-displacement reactions occur when one element replaces another element in a compound
• In a double-displacement reaction the positive ion of one compound replaces the positive ion of the other to from two new compounds.
• Evidences that a chemical reaction has taken place are gas production, new substance or precipitant formed, color change, absorbing or releasing energy
• Combustion is a type of reaction in which Oxygen is always a reactant and carbon dioxide and water are products.
Students will be able to do(Skills)
• Balance chemical equations
• Identify the different types of chemical reactions
