9 Chemicalreaction Equations Lessonplan Vinay
Instructional Objectives
- Write and balance simple chemical equations
- Describe the significance of a balanced chemical equation
- Explore the relationship between mole, mass and volume of various reactants and products
- Classify chemical reactions as combination, decomposition, displacement and double displacement reactions
- Define oxidation and reduction processes (redox reactions) and correlate these with corrosion and rancidity and other aspects of daily life.
Teaching Process
- Representation of chemical change in the form of an equation
- Balancing chemical equations - Lots of practice and relating to law of conservation of mass
- Significance of balanced chemical equation
- Different types of chemical reactions eq: displacement, exothermic, redox, thermal decomposition, combustion, double decomposition etc etc - Experiments are carried out to demonstrate the reactions
- Redox Reactions in terms of Electron gain and Electron Loss.
- Concept of corrosion and it's prevention
