Question

Balance Redox Equations (Acidic Solutions) show steps please.

1. HgS (s) + NO3^- (aq) + Cl^- (aq) = HgCl4^2- (aq) + NO (g) + S (s)

2. Fe^2+ (aq) + MnO4^- (aq) = Fe^3+ (aq) + Mn^2+ (aq)

3. BiO3^- (aq) + Mn^2+ (aq) = MnO4^- (aq) + Bi^3 (aq)

4. NiO2 (s) + Ag (s) = Ni^2+ (aq) + Ag^+ (aq)

5. IO3^- (aq) + I^- (aq) =I2 (s)

6. Zn (s) + H2SO4 (aq) = Zn^2+ (aq) + H2S (g)

Answer 1

(ar) D Hg S (3) + NO + cd glo- & MOTS s goes from - to o log (lose 2 e) N goes from t5 to 42 gains 3e) " 3 moles of Hgs are required for a moles of No3 . The reaction is 3 Hgs + 2NO3 + e + 3 H 2 + 2N0 + 35 Now balance cl and add it on the left and H₂O on the right to balance o. . The balanced reaction is 3Hgs + 2007 + 1200 + 8H+ + 3 Hgce? + 2NO+35+ 4H2OU) Follow the same process for each one 92) Fe goes from +2 to t3 closes le) - Mn " " +7 to +2 (boses se-) 5fe2+ + mnou 5fe3+ + Mu add itt and H₂O 5fe2t + Mnou +84 + sfest & Mu2+ + 4H₂Ou) 3) Bi goes from t5 to +3 (gains a e`) Mn goes from t2 to +7 closes sel : 5 Bioz + 2 mut+14H+ 2 Mnou + Bi. 3+ + 7H2O 4) Ni goes from +4 to +2 Ag goes from o to ti : HiO₂ + 2 Ag+ 4H+ Ni2+ & Agot + 2 H2O Jains 5 fet (9)

Please post the last 2 separately.
