Not all organic solvents are suitable for liquid-liquid extraction with an aqueous solution. list at least three such solvents; make sure each of the three bears a different functional group. your answer arises from a general rule regarding miscibility of organic molecules with water. what is the ""rule of thumb""?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

Which is the best for showing percentages of different types of cars sold(gas hybrid , electric , other ) in the united states ?

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1
