The question is do you need to convert volts into something else when using it in the equation of (planks constant x speed of light / volts) or can I leave in volts? or should I convert volts to lambda?
A half-cell that consists of a copper wire in 1.00 M CuNO3 solution is connected by a salt bridge to a half cell containing a 1.00 M X(II) acetate solution and an electrode of metal X. The voltage of the cell is 1.37 V, with metal X as the positiv..
What will be the final concentrations of NH3,N2, and H2 after equilibrium is established. I know the answers are suppose to be H2=.170M, NH3=.0424M, N2=.0568M, but I don't know how to get them.
How much water must be added to 562 mL of 0.200 M HCl to produce a 0.148 M solution? (Assume that the volumes are additive.)
Calculate the molar solubility of AgBr in a 1.00 M aqueous solution of ammonia. Then calculate the solubility of AgBr in pure water, and compare the two solubilities. (Ksp for silver bromide is 7.7x10 -13 and Kf for Ag(NH3)2+ is 1.6x10^7)
