1.Silver is sometimes found in nature as large nuggets; more often it is found mixed with other metals and their ores. An aqueous solution containing cyanide ion is often used to extract the silver using the following reaction that occurs in basic solution: Acid Ag(s) + CN¯(aq) + 02(g) Ag(CN), (aq) Balance this equation using the half-reaction method.

1.Silver is sometimes found in nature as large nuggets; more often it is found mixed with other metals and their ores. An aqueous solution containing cyanide ion is often used to extract the silver using the following reaction that occurs in basic solution: Acid Ag(s) + CN¯(aq) + 02(g) Ag(CN), (aq) Balance this equation using the half-reaction method. 2. Consider a galvanic cell based on the following reaction: Al* (aq) + Mg(s) → Al(s) + Mg** (aq) The half-reactions are: Al³* + 3e -→Al E° = –1.66 V (1) E° = -2.37 V (2) Mg**+ 2e →Mg Give the balanced cell reaction and calculate E° for the cell.
