Consider a tank used in certain hydrodynamic experiments. After one experiment the tank contains 150 liter (L) of a dye solution with a concentration of 3 g/L. To prepare for the next experiment, the tank is to be rinsed with fresh water flowing in at a rate of 3 L/min, the well-stirred solution flowing out at the same rate. Find the time that will elapse before the concentration of dye in the tank reaches 2% of its original value

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
