An unknown metal, x, was placed in a solution of CuCl2(aq) and black solid appeared on the metal. However, when metal x was placed in the solution of ZnCl2(aq), no observable change occurred. What is the possible identity of metal X? Explain your reasoning

Balance the following redox equations. All occur in basic solutions. (A) Fe(OH)3(s) + Cr(s) --> Cr(OH)3(s) + Fe(OH)2(s)  (B) NiO2(s)  + Zn(s) --> Ni(OH)2(s) + Zn(OH)2(s) (C) Fe(OH)2(s) + CrO42-(aq) --> Fe(OH)3(s) + [Cr(OH)4]-(aq) (D) N2H4(aq) + Ag2O(s) --> N2(g) + Ag(s)

A sample of impure tin of mass 0.530 gg is dissolved in strong acid to give a solution of Sn2+Sn2+. The solution is then titrated with a 0.0448 molL−1molL−1 solution of NO3−(aq)NO3−(��), which is reduced to NO(g)NO(�). The equivalence point is reached upon the addition of 3.91×10−2 LL of the NO3−(aq)NO3−(��) solution.   Part A Find the percent by mass of tin in the original sample, assuming that it contains no other reducing agents.

Balance the following reaction in acidic solution. Fe?+ (ag) + MnO, (aq) → Fe+ (ag) + Mn²+(aq) Fill in the coefficients and substances for the balanced overall equation. Note: Do NOT leave any coeffient fields empty. If the coefficient is 1, choose "1" as opposed to leaving it blank. Fe2+ + MnO,¯ + 4 Fe3+ + Mn2+ +
