A
To balance a half reaction, first the atoms other than hydrogen and oxygen are balanced. After balancing the other atoms,
(b)
Interpretation:
The given reaction should be balanced using the half reaction method in the acidic solution.
Concept Introduction :
A balanced chemical reaction is the reaction having same number of all the constituent atoms on both sides of the reaction arrow.
A redox reaction can be balanced using the half reaction method. In this method, the redox reaction is first divided into two half reactions that is oxidation and reduction.

- For the reaction Cu2+(aq) + Zn(s) → Cu(s) + Zn2+ (aq), why can’t you generate electric current by placing a piece of copper metal and a piece of zinc metal in a solution containing CuCl2(aq) and ZnCl2(aq)?arrow_forwardAssign an oxidation number to the underlined atom in each ion or molecule. (a) Fe2O3, (b) H2SO4, (C) CO32- (C) NO2+arrow_forwardOne of the few industrial-scale processes that produce organic compounds electrochemically is used by the Monsanto Company to produce1,4-dicyanobutane. The reduction reaction is 2CH2CHCH+2H++2eNC(CH2)4CN The NC(CH2)4CN is then chemically reduced using hydrogen gas to H2N(CH2)6NH2, which is used in the production of nylon. What current must be used to produce 150.kg NC(CH2)4CN per hour?arrow_forward
- Write balanced equations for the following half-reactions. Specify whether each is an oxidation or reduction. (a) H2O2(aq) O2(g)(in acid) (b) H2C2O4(aq) CO2(g)(in acid) (c) NO3(aq) NO(g)(in acid) (d) MnO4(aq) MnO2(s)(in base)arrow_forwardFour metals, A, B, C, and D, exhibit the following properties: (a) Only A and C react with 1.0 M hydrochloric acid to give H2(g). (b) When C is added to solutions of the ions of the other metals, metallic B, D, and A are formed. (c) Metal D reduces Bn+ to give metallic B and Dn+. Based on this information, arrange the four metals in order of increasing ability to act as reducing agents.arrow_forwardUse Table 17.1 to arrange the following oxidizing agents in order of increasing strength: Mn2+ S Co3+ Cl2 K+arrow_forward
- Order the following oxidizing agents by increasing strength under standard-state conditions: Mg2+(aq), Hg2+(aq), Pb2+(aq).arrow_forwardWrite balanced equations for the following half-reactions. Specify whether each is an oxidation or reduction. (a) Cr(s) Cr3+(aq)(in acid) (b) AsH3(g) As(s)(in acid) (c) VO3(aq) V2+(aq)(in acid) (d) Ag(s) Ag2O(s)(in base)arrow_forward
