2.40 kj of heat is added to a slug of platinum and a separate 2.40 kj of heat is added to a slug of zinc. the heat capacity of the platinum slug is 209j/°c while the heat capacity of the zinc slug is 575 j/°c. if the slugs are each originally at 25.00°c, what is the final temperature of each slug?

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
