i love the animater of these videos its not colorfull but not dull etheir the color range is perfect
do you get given one of the values. like how do you know wha5 the actual or theoretical yield is
Thanks sooooo much sir. This video is very helpful to me😘. You are brilliant teacher👌👍🏻❤️
your videos are always helpful but could you tell us how to find the actual yield because in the exam we can not guess
I got it thanks to this video but it'd be better if there was be difficult questions
Very useful
Will you guys make organic chemistry vieos again?
Hi do your videos follow a particular exam board? I love your videos so much and they are extremely helpful!

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
thank you so very much for the video my chemistry teacher is a hack and refuses to explain and teach- ur literally carrying me thru exam season tytyty
thanks professor greeat work

practical, the theoretical is just what you think is the mass that will be produced , not what is actuall produced
which one is the yield formula?

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