The voltage generated by the zinc concentration cell described by the line notation Zn(s) || Zn2+(aq,0.100 M) ‖‖ Zn2+(aq,? M) || Zn(s)

is 25.0 mV at 25 °C. Calculate the concentration of the Zn2+(aq) ion at the cathode.

If a gas has an initial pressure of 101kpa and a volume of 10l, then it expands to a volume of 20l, what is the new pressure?

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?
