In the production of ethanol by fermentation, why is the process done at an optimal temperature of 30⁰C?To prevent the reaction happening too quickly, leading to a dangerous build up of ethanolSo that the yeast is warm enough to catalyse the reaction between oxygen and sugar to produce ethanolTo increase the life span of the yeast, so the production doesn\'t have to be stopped often to replace themSo the yeast is warm enough to perform anaerobic respiration, but below the temperature at which the zymase enzyme would denatureQuestion 7 of 14 Loading... 8. magnesium + ethanoic acid →magnesium + ethanoic acid → magnesium ethanoate + watermagnesium + ethanoic acid → magnesium ethanoide + watermagnesium + ethanoic acid → magnesium ethanoide + hydrogenmagnesium + ethanoic acid → magnesium ethanoate + hydrogenQuestion 8 of 14 Loading... 9.
