      Hi! They’re not specific to just one, we write them to cover the material for all the main exam boards. The descriptions highlight any bits you might be able to leave out for your specific exam board

      practical, the theoretical is just what you think is the mass that will be produced , not what is actuall produced

      A little late, if you have the % yield and theoretical, you just do %yield x Theoretical yield
