Question

Balance the following redox reaction if it occurs in basic solution. What are the coefficients in front of Cr and I_2 in the balanced reaction? Cr(s) + I_2(g) rightarrow Cr^3+(aq) + I^- (aq) Cr = 3, I_2 = 2 Cr = 2, I_2 = 3 Cr = 1, I_2 = 1 Cr = 2, I_2 = 1 Determine the cell notation for the redox reaction given below. Fe(s) + 2 Ag^+ (aq) rightarrow Fe^2+ (aq) + 2 Ag(s) Fe(s) | Fe^2+(aq) | Ag^+(aq) | Ag(s) Ag^+(aq) | Ag(s) || Fe(s) |Fe^2+(aq) Ag(s) | Ag^+ (aq) || Fe^2+ (aq) | Fe(s) Fe(s) | Ag(s) | Ag(s) || Fe^2+ (aq) | Ag^+(aq) Based on the following information, Br_2(l) + 2 e^- rightarrow 2 Br^-(aq) E degree = +1.09 V Mg^2+ (aq) + 2 e^- rightarrow 2 Mg(s) E degree = -2.37 V which of the following chemical species is the strongest reducing agent? Br^-(aq) Mg^2+ (aq) Mg(s) Br_2(l) The standard emf for the cell using the overall cell reaction below is +0.48 V; Zn(s) + Ni^2+(aq) rightarrow Zn^2+ (aq) + Ni(s) The emf generated by the cell when [Ni^2+] = 0.100 M and [Zn^2+] = 2.75 M is _____V. 0.52 0.50 0.57 0.44 0.39 Name the following compound. nonane 3-ethyl-3-methylhexane 3-ethyl-3-propylbutane 3-methyl-3-propylpentane 2-ethylheptane Which of the following compounds exhibits geometric isomerism? CH_2-CH-CH_3 CH_3-CCl-CCl-CH_3 CCl_2-CF_2 CBr_2-CHBr All of the above exhibit geometric isomerism.
