I recently fell ill and had to miss some classes, so I spent time looking at questions I found difficult. I never really comment on these types of videos as they usually just refresh my memory or contribute to my foundation of future knowledge. Though, this video in particular helped me understand something I immensely struggled with, even when being taught by three different chemistry teachers. You explain every little detail so thoroughly, even giving reasons behind why we use such formulae or units instead of just explaining the method. I can tell you that this really helps, as it's much easier to do something if you know exactly WHY you're doing it. I can't thank you enough for the way that you attend to difficult topics like these, and I can now confidently say this'll be the first channel I go to for any misunderstood topics of mine. Keep it up :)

Ugh I’ve been looking all over the internet for a vid on this to help me understand the concept. This video is helping me at A level and for once I found a useful vid which clearly explains this concept. Thank you!!

Thanks man, I have a chemistry exam soon and feel rather lazy to really understand through my textbook. And your video was short and concise exactly to the point making me understand alot better and save me time.
