Tutorial 3 the mole and stoichiometry

A balanced equation shows, in terms of moles, how much of each substance is involved in the reaction. stoichiometry is the study of the relationships of quantities of substances in a chemical reaction. consider the reaction:(1) fecl 3(aq) + 3naoh (aq) → fe(oh) 3(s) + 3nacl (aq) this balanced equation tells us: one mole of iron(iii)...
