What type (redox, acid-base, precipitation) are the reactions below? For the redox reactions, identify the oxidizing and reducing agent, and the oxidation numbers of atoms in each species.   a. FeCl3 +          Cu                    -->        FeCl2                +          CuCl

2. For each reaction shown, identify the oxidizing agent and the reducing agent (for the forward reaction). If the reaction is not a redox reaction, just check the box for "no redox". Also for each redox reaction, figure out "n", the number of electrons involved in the overall balanced equation. no reaction OA RA n = redox Mg + 2 H* -→ H2 + Mg²+ CO2 + H20 → H2CO3 4 FeO + O2 → 2 Fe,O3 2 Н-О + 10 МnO, + 3 Cl, —> 10 MnO, + 6 CIO; + 4 Oн- 2 Ag* + S?- → Ag,S 3 Zn + 2 NO3 + 8 H+ → 3 Zn²+ + 2 NO + 4 H,O 2 Н.О > 2 Н-О + О2

Use the oxidation states method to balance the reaction:    __ SO42– (aq)   +   __ Fe2+ (aq)     +   __ H+ (aq)       -->      __ SO2 (g)   +   __ Fe3+ (aq)     +   __ H2O (l)

Zn(s) + 2 AgNO3(aq) → Zn(NO3) 2(aq) + 2 Ag(s)b. 2 Li(s) + Fe(C 2H3O 2) 2(aq) → 2 LiC2H3O 2(aq) + Fe(s)c. Ni(s) + 2 AgClO 4(aq) → Ni(ClO4) 2(aq) + 2 Ag(s)For each reaction, assign oxidation states to each element on the reactant and product side of thereaction. In addition, answer the following questions: Which element is being reduced? Which is beingoxidized? What is the reducing agent? What is the oxidizing agent?

2. Acetic acid (HC2H3O2) is an important component of vinegar. A 10.0-mL sample of vinegar is titrated with 0.255 M NAOH, and 13.5 mL are required to neutralize the acetic acid that is present. a. Write a balanced equation for this neutralization reaction. b. What is the molarity of the acetic acid in this vinegar? c.lf the density of the vinegar is 1.006 g/mL, what is the mass percent of acetic acid in the vinegar?

Use the oxidation states method to balance the reaction:    __ SO42– (aq)   +   __ Fe2+ (aq)     +   __ H+ (aq)       -->      __ SO2 (g)   +   __ Fe3+(aq)     +   __ H2O (l)
