Question:

1 Balance the following half reactions and determine whether they are oxidation or reduction reactions a) NO NO. b) Mno. Mn c) Fe(OH)30s Fe 2 Chapter 1,Exercise fi9: 9. The chemistry laboratory returns the following water analysis: pH 6.3 Na mg/liter 0.5 mg/liter Mg 0.3 mg/liter CIT 1.5 mg/liter soa 2 mg/liter NO3 0.5 mg/liter HCO3 0.9 mg/liter. Is this analysis both complete and accurate? Explain why or why not. Hints: -Use the electroncutrality principle. Table of atomic weight are uploaded under week 1. 3- 0.01 mol each of acetic acid (HAc and ammonia (NH3) are added to a liter of water. List the chemical species and the constraints on the system at equilibrium. Page 1 of 2
Balance the following half reactions and determine whether they are oxidation or reduction reactions NO_3 = NO_2 Mno_4 = Mn^2+ Fe(OH)3(S) = Fe^2+ The chemistry laboratory returns the following water analysis: pH = 6.3 Na+ = mg/liter K^+ = 0.5mg/liter Mg^2+ = 0.3mg/liter CI^- = 1.5 mg/liter SO^2-_4 = 2mg/liter NO_3^- = 0.5 mg/liter HCO_3^- = 0.9 mg/liter. Is this analysis both complete and accurate? Explain why or why not. 0.01 mol each of acetic acid (HAc) and ammonia (NH_3) are added to a liter of water. List the chemical species and the constraints on the system at equilibrium.
