Description
This unit covers writing chemical formulae, balancing equations, and using the conservation of mass. It includes calculating moles, empirical formulae, relative formula masses, and theoretical yields. Emphasis is on stoichiometry, concentration, gas volumes, and using standard form.
This unit builds on pupils’ prior learning from Understanding chemical reactions, where they explored how substances interact and rearrange during reactions. It deepens their understanding by focusing on calculations involving masses, such as relative formula mass, moles, and stoichiometry. This prepares pupils for the next unit, Making salts, where they will apply these calculation skills to chemical reactions involving acids and bases, reinforcing their understanding of quantitative chemistry and the practical applications of reaction yields.
