Hydrogen (commercial production, laboratory preparation, properties, uses, test); Halogens — chlorine as representative (preparation, properties, uses e.g. water sterilization, bleaching, HCl/plastics/insecticide manufacture) and HCl/hydrochloric acid (preparation, properties, chloride tests); Oxygen and Sulphur — preparation, properties, uses, oxide classification, ozone, sulphur allotropes, SO₂, trioxosulphate(IV) acid, H₂SO₄ (contact process) and H₂S, with relevant ion tests; Nitrogen — preparation, ammonia (Haber process, properties, uses, ammonium salts, oxidation to HNO₃), trioxonitrate(V) acid, oxides of nitrogen, the nitrogen cycle, with relevant ion tests; Carbon — allotropes, CO₂ and CO (preparation, properties, uses, effects), coal and coke (types, destructive distillation products, synthesis gas).
- Predict reagents for the laboratory and industrial preparation of these gases and their compounds.
- Identify, compare and specify the properties and uses of each.
- Determine specific tests for each gas, compound and relevant ion (Cl⁻, SO₄²⁻, SO₃²⁻, S²⁻, NH₄⁺, NO₃⁻, CO₃²⁻, HCO₃⁻).
- Identify allotropes of oxygen, sulphur and carbon and their significance/uses.
- Specify the laboratory/industrial preparation, properties and uses of NH₃ and HNO₃.
- Examine the relevance of the nitrogen cycle.
- Predict reagents for CO₂/CO preparation and their properties and effects.
- Identify types of coal and the products of destructive distillation of wood and coal, and specify uses of coke and synthesis gas.
Try a few questions
- Practice question 1
Ammonium trioxonitrate(V) (ammonium nitrate) is mainly valued as a
- A.strong household bleaching agent
- B.reagent used exclusively for softening hard water
- C.nitrogen-based fertilizer, due to its high nitrogen content
- D.raw material for glass manufacture
Show the answer
C. nitrogen-based fertilizer, due to its high nitrogen content
Its high nitrogen content makes ammonium nitrate a widely used and effective agricultural fertilizer.
- Practice question 2
Oxides such as carbon(IV) oxide and sulphur(IV) oxide, which react with bases to form salts, are classified as
- A.acidic oxides
- B.basic oxides
- C.amphoteric oxides
- D.neutral oxides
Show the answer
A. acidic oxides
These non-metal oxides behave like acids, reacting readily with bases, hence their classification.
- Practice question 3
The nitrogen cycle mainly describes how nitrogen
- A.remains permanently locked within the atmosphere with no further movement
- B.is entirely destroyed once absorbed by plants
- C.moves through the atmosphere, soil, and living organisms via processes like fixation, nitrification, and denitrification
- D.only ever exists in a single, unchanging chemical form
Show the answer
C. moves through the atmosphere, soil, and living organisms via processes like fixation, nitrification, and denitrification
The nitrogen cycle traces nitrogen's continuous transformation and movement through various environmental reservoirs.
