Hi, Is there a difference between yeast and yeast nutrients? This is in the context of an ethanol fermentation practical, also, is there a way to know how much yeast, yeast nutrient, glucose and water are required for fermentation to occur optimally? Thanks!!!

@jazz519 Would you be able to help with my question? Thanks if you could! " Is there an estimate of how much yeast I should use? in relation to the amount of glucose, I will use." this is in relation to alcoholic fermentation practical.

Also, is there an estimate of how much yeast I should use? in relation to the amount of glucose I will use. Sorry for any inconvenience!!

Thanks for the responses so far, for the product of Ethanol (aq), would we have to use fractional distillation to separate the water and ethanol? I might be wrong, but I'm pretty sure that is the method to determine the amount of ethanol. Right?

Hi! So I recently got a prac for chem and was confused (I mean really confused) on a method for the fermentation of glucose, the necessary equipment to carry out an experiment and the required calculations to fulfil the aim. The aim is to determine the amount of ethanol produced due to the...

I believe, so, substitution reactions with Cl2 or Br2 utilise UV Light, correct me if I'm wrong.

Hi! I was stuck on two questions from the Cambridge Mathematics Extension 1 Textbook => Exercise 5G Q14 and Q17. - I was able to do the graphing and working out but I got the wrong answer from the textbook answers. Could someone help me with worked solutions, so I can see where I went wrong...

Hope this serves your endeavours well. :)
