IB Chemistry HL 2.1.1 Chemical equations
Practise writing balanced equations with correct formulas and state symbols, and deducing missing products or coefficients from the reaction details given.
How this is tested
- write balanced equations with state symbols for reactions such as CaCO3(s) + 2HCl(aq) → CaCl2(aq) + CO2(g) + H2O(l)
- deduce a missing product and balance the full equation, for example 2NO(g) + 2CO(g) → 2CO2(g) + N2(g)
- balance coefficient questions from reagent and product formulas, including Cu + 4HNO3 → Cu(NO3)2 + 2NO2 + 2H2O
