Random JAMB Chemistry Past Questions (CBT Practice) Series
Practice random JAMB Chemistry past questions in CBT format and strengthen your understanding of key concepts. This series features questions from different JAMB years covering atomic structure, chemical bonding, calculations, organic, and inorganic chemistry. Ideal for consistent exam preparation.
Chemistry Practice: Molar Calculations, Hydrocarbons & Oxidation
Sharpen your chemistry skills with this focused practice set. This quiz covers critical molar concentration calculations (finding moles in 200 cm³ of HCl) and molecular formula determination based on empirical formulas (CH₂O) and molar mass (180 g/mol). Test your knowledge of organic reactions, including the oxidation of ethanol to ethanoic acid, the hydrogenation of benzene, and the burning of methane in excess air. Additionally, review key laboratory concepts like acid–base indicator colors (phenolphthalein in acid), the functional differences between aldehydes and ketones, and the composition of rust on metal surfaces.
JAMB Chemistry CBT Practice: Perfume Making, Catalysts & Bonds
Test your chemistry knowledge with this advanced practice set. This quiz explores the bonding in oxonium ions and naphthalene molecules, as well as the behavior of catalysts in chemical reactions. Challenge yourself with STP calculations to find the relative molecular mass of gases and identify which hydrocarbons undergo both addition and substitution reactions. We also cover practical laboratory chemistry, including the use of charcoal in water treatment, the production of perfumes, and the reaction of ammonia to produce dense white fumes. Perfect for students reviewing equilibrium constant (Kc) factors and the purity of natural water sources.
Chemistry Practice: Combustion, pH, and Particulate Nature of Matter
Challenge your understanding of chemical properties with this interactive set. This practice quiz covers acidic oxides, pH levels of solutions, and the particulate nature of matter. Test your ability to balance combustion equations for unknown hydrocarbons (CₓHᵧ) and identify the reaction products of methylethanoate and ammonia. We also dive into environmental chemistry with questions on gaseous pollutants, the crystalline structure of ice, and the internal energy of ideal gases. Finally, master laboratory techniques by identifying the correct drying agents for Hydrogen gas (H₂).
