Life Cycle Assessment and Chemical Equilibrium
Concepts covered:Life Cycle Assessment, Environmental Impact, Reduction Strategies, Chemical Equilibrium, Le Chatelier's Principle
Exploration of life cycle assessment (LCA) for predicting environmental impact of new products, emphasizing reduction strategies. Detailed explanation of chemical equilibrium principles, including Le Chatelier's principle and factors affecting equilibrium position.
Question 1
How does temperature affect endothermic reactions?
Question 2
What happens if pressure increases in a reaction?
Question 3
What is the purpose of an LCA?
Ammonia Production and Acid-Base Titration Process
Concepts covered:Ammonia production, Haber process, Acid-base titration, Sodium hydroxide, Sulfuric acid
The chapter discusses the process of producing ammonia through the Haber process, emphasizing the importance of temperature and pressure for optimal yield. It also explains the acid-base titration method using sodium hydroxide and sulfuric acid as an example.
Question 4
How many moles of acid neutralize 0.01 moles of alkali?
Question 5
Why is 450°C used in the Haber process?
Question 6
What is the concentration of 0.005 moles in 0.125 DM³?
Chemical Reactions, Alloys, and Batteries
Concepts covered:Gas volume, Chemical reactions, Alloys, Metal corrosion, Batteries
Gas volume, chemical reactions, metal corrosion, alloys, and batteries are discussed. Alloys strengthen metals, batteries generate voltage, and hydrogen fuel cells produce electricity.
Question 7
How are rechargeable batteries recharged?
Question 8
Why are alloys generally stronger than pure metals?
Question 9
Why is zinc used to galvanize iron?
