Answer by sue monteath on question Chemical reactions year 10
Year 10 science requires students to know and understand that “Different types of chemical reactions are used to produce a range of products and can occur at different rates”. This doesn’t specify a definitive set of reactions, however, in exploring this content descriptor, learning experiences should probably include a range of reactions like: oxidation (mg and oxygen), neutralisation (HCl and NaOH), and decomposition (hydrogen peroxide). It is very likely that students would need to write both word and (balanced) symbol equations to represent the reactions.
