PLEASE HELP ME WITH THIS I NEED THIS ASAP Generally speaking, as there is a greater discrepancy (difference) between the number of protons and the number of neutrons in elemental isotopes, radioactivity does what in terms of quantity?

Ethanol (c2h5oh) is produced from the fermentation of sucrose in the presence of enzymes. c12h22o11(aq) + h2o(g) 4 c2h5oh(l) + 4 co2(g) determine the theoretical yield and the percent yields of ethanol if 680. g sucrose undergoes fermentation and 326.5 g ethanol is obtained. theoretical _ g _ percent %
