I need to identify the cations A through G as K+, Cu2+, Ag+, Ba2+, Fe3+, Mg2+,...

I need to identify the cations A through G as K+, Cu2+, Ag+, Ba2+, Fe3+, Mg2+, or Pb2+ The unknown cation is Br-/OH- From what I believed I've figured out is: K+ = F Cu2+ = A or E Ag+ = B or C Ba2+ = G Fe3+ = A or E Mg2+ = A or E Pb2+ = D I believe this may be correct but I am unable to figure out Cu2+, Ag+, Fe3+, and Mg2+. I also...

In paper chromotography, what form are the metals ( Zn2+, Co2+, Cu2+, Cd2+ , Fe3+, and Ni2+) ions likely to exist in the moving phase (water/hydrochloric acid/acetone) and what groups in the structure of the stationary phase (cellulose) are interacting with the moving ions in solution? Note: Filter paper (Whatman #1) serves as the stationary phase, and the mobile phase consists of a mixture of acetone and 6 M hydrochloric acid. A single spot of the mixture to be analyzed...

(a) What is the Black-Scholes Partial Differential Equation for the price f(t,St) at time t of a European derivative security on a stock with price St? Specify the meaning of the terms or symbols in the equation. (b) Note that the Black-Scholes Partial Differential Equation does not specify whether the derivative is a call option, a put option, or some other derivative. How do you incorporate the derivative payoff when using Black-Scholes PDE to price a derivative?
