Problem- What hydrogen ion concentration should be required to dissolve 0.10M MgF2 if the Ksp for magnesium fluoride is 6.8x10^-9 and Ka for HF is 6.5x10^-4?
Show all work I'm being very generous with points.
Consider the reaction: CO(g)+Cl2(g)===COCl2(g) Keq= 2.9×10^10 at 25 degress celsius A 5.89 -L flask containing an equilibrium reaction mixture has [CO]= 1.4×10^?6M and = 6.3×10^?7M How much COCl2 in grams is in the equilibrium mixture
A flask contains 0.190 mol of liquid bromine, rm Br_2. Determine the number of bromine molecules present in the flask.
Isobutane is the fuel used in disposable lighters. The lighters' operation is dependent upon the butane's ability to vaporize and be ignited, and this depends somewhat upon the large pressure difference between the inside of the lighter and the at..
the volume of an ideal gas is held constant. determine the ratio p2p1 of the final pressure to the initial pressure
The equilibrium constant for the reaction N2(g) + 3H2(g) = 2NH3(g) is Kp=4.34x10^-3 at 300*C. Pure NH3 is placed in a 1.00 L flask and allowed to reach equilibrium at this tempurature. What is the mass of N2 in the equilibrium mixture
