Chemistry Practice: pH Calculations, Atomic Radii & Gas Expansion Quiz
Test your understanding of chemical principles and practical applications with this targeted practice set. This quiz covers pH and hydronium ion $[H₃O⁺]$ concentrations, the identification of irritant oxide pollutants like $SO_2$, and the hydration of alkenes to form alcohols. Explore the reactivity of metals, specifically the reaction of calcium with water and the thermal decomposition of potassium nitrate (KNO₃). We also analyze why aluminium alloys are essential for aerospace engineering, the physical process of diffusion in solids, and the kinetic molecular theory explaining why gases expand when heated. Finally, sharpen your knowledge of atomic radius trends and the location of the reducing agent in electrochemical cells.
