Explore comprehensive mathematics assessments & practice modules.
Master biological concepts and cellular theory with interactive exams.
Test chemical equations, organic reactions & lab questions.
This mock strengthens formulae, equations, relative masses and foundational mole calculations before moving into limiting reactants, solution concentration, titration, empirical formula and percentage yield.
This revised Extended mock raises the demand level while remaining within Unit 3 Stoichiometry. It assesses formulae and equations, relative masses, the mole and Avogadro constant, molar gas volume at r.t.p., reacting quantities, solution concentration, titration, empirical and molecular formulae, percentage composition, yield and purity. Several items now require two or more linked steps rather than direct substitution.
This 20-question Extended mock assesses graphite, diamond, silicon(IV) oxide, metallic bonding and structure-property relationships. It integrates conductivity, hardness and deformation evidence so students connect experimental observations to bonding models.
