Description
Dear Learner,
This module explores the significant role of chemistry in industry, focusing on the processes that convert raw materials into valuable chemical products. Key topics include the industrial production of ammonia (via the Haber process), sulfuric acid (through the contact process), nitric acid, and nitrogen-based fertilizers. Additionally, the module discusses the manufacturing processes of various other chemicals and materials, such as sodium hydroxide, glass, cement, and ceramics. It also highlights local industries in Ethiopia, covering sectors such as sugar production, tanning, and food preservation.
Key Topics: Natural resources and industrial Applications manufacturing processes of essential chemicals (ammonia, sulfuric acid, nitric acid)Local industry relevance (glass, ceramics, cement, and sugar production)Industrial applications in Ethiopia (tanning, insecticides, food preservation),
This module also focuses on the chemistry of polymers, which are large molecules made up of repeating smaller units called monomers. The module covers the two main types of polymerization: addition and condensation reactions. It explains the difference between thermoplastic and thermosetting polymers, discussing the structure, classification, and applications of natural and synthetic polymers. Students learn about the industrial importance of polymers, especially in the production of plastics, rubbers, and synthetic fibers, and explore how polymers have transformed industries and daily life.
Key Topics: Structure and classification of polymers (natural and synthetic) Types of polymerization reactions (addition vs. condensation) Industrial applications of polymers (plastics, rubber, and fibers)Thermoplastic vs. thermosetting Polymers and
This module also examines the chemical processes occurring in the environment and the impact of human activities on these processes. It covers the major components of the environment (atmosphere, hydrosphere, lithosphere, and biosphere) and explores natural cycles such as the carbon, nitrogen, and water cycles. The module also addresses pollution in its various forms (air, water, and land), its causes, effects, and mitigation strategies. A major focus is on global environmental issues like global warming and climate change. The module introduces green chemistry principles aimed at minimizing pollution and promoting sustainable chemical production methods.
