Alcohols & Carboxylic Acids quiz Loading... 1. 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 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 denatureSo that the yeast is warm enough to catalyse the reaction between oxygen and sugar to produce ethanolQuestion 1 of 14 Loading... 2. What is the molecular formula of butan-1-ol?C₂H₆OCH₄OC₄H₁₀OC₄H₁₂OQuestion 2 of 14 Loading... 3. sodium carbonate + ethanoic acid →sodium carbonate + ethanoic acid → sodium ethanoate + carbon dioxide + watersodium carbonate + ethanoic acid → sodium ethanoide + carbon dioxide + watersodium carbonate + ethanoic acid → sodium ethanoate + carbon dioxide + hydrogensodium carbonate + ethanoic acid → sodium ethanoide + carbon dioxide + hydrogenQuestion 3 of 14 Loading... 4.
