What is the % efficiency of the separation? (i.e. If X represents the anion that precipitates first, then what fraction of X was precipitated from the solution at the instant the second precipitate starts to form?)
1-mL of 0.007 M Na2SO4 was diluted in 100-mL of deionized water. What is the concentration of the Na2SO4 in ppm
The best design for rockets is one in which both fuel materials run out at the same time to minimize excess mass. If the total mass of both components in a decaborane/oxygen rocket must be 3.011E+6g, what mass of liquid oxygen should be used
A sealed tube contains 1.66 atm PCl5 at 500 K. The PCl5 decomposes until equilibrium is established. The equilibrium pressure in the tube is 2.28 atm. Calculate Kp for this equilibrium.
a first order reaction has a rate constant 0.00510.if we begin with 0.10 M concentration of the reactant , how much of the reactant will remain after 3 hrs?
The relationship between Kp and Kc for gaseous reactions depends on the change in the total moles of gas between reactants and products. For each of the equations given at the right, select the correct relationship between Kp and Kc from the list ..
