What are four things which could be done in order to increase the yield?
you could either use a catalyst which is basically a type of concentration which speeds the reactions up or just wait for the reactions to happen !!

Which 3 types of reactions are ALWAYS redox reactions?
Redox reactions are divided into two main types.(i) Inter molecular Redox:In such redox reactions, one molecule of reactant is oxidized whereas molecule of other reactant is reduced.(ii)Intra molecular Redox:One atom of a molecule is oxidized and other atom of same molecule is reduced then it is intramolecular redox reaction.e.g., 2Mn2O7 4MnO2 + 3O2.
What are four ways that chemists control the rates of chemical reactions?
