Please answer the second multiple choice. When the potential a half reaction was measured against a Ag|AgCl reference electrode, thepotential was found to be –-0.548 V. What would the potential when the same half reaction wasmeasured against a S.C.E. reference electrode?a. -0.592 Vb. 0.592 Vc. -0.351 Vd. 0.504 Ve. -0.504 VWhen using EDTA to determine metal ion concentration in a solution, what is the best way toovercome a slow equilibrium between the metal ion analyte and EDTA?a. Use a masking agent.b. Use an auxiliary complexing agent.c. Perform a displacement titration.d. Perform an indirect titration.e. Perform a back titration.

Masking agent is used to protect some component of the analyte from the reaction with EDTA and thus…

A hydrogen atom is heated up causing an electron to be excited to a level which we will call E2. When the electron falls back to the E1 energy level, it emits a photon of light. The photon has an energy of 267.039 fJ. What is the energy change (∆E) of the electron when it falls from E2 to E1? Enter your answer just as a number with units of fJ. ∆ is final minus initial. Recall from thermo that the total energy change will be zero. (Light always has a positive energy).
