Answer to Question #131370 in General Chemistry for Muhammad Hussein Aliefianto

Question

Balance the following equation for the redox reaction by saying

A. Cu (s) + NO3- (aq) + 4 H+ (aq) → Cu 2+ (aq) + NO (g) + 2 H2O (l)

B. Cl2 (g) + 6 OH- (aq) → Cl- (aq) + ClO3- (aq) + 3 H2O (l)

Answer 1

A.

3 Cu (s) + 2 NO₃^- (aq) + 8 H⁺ (aq) → 3 Cu²⁺ (aq) + 2 NO (g) + 4 H₂O (l)

3 Cu + 8 HNO₃ → 3 Cu(NO₃)₂ + 2 NO + 4 H₂O

B.

3 Cl₂ (g) + 6 OH^- (aq) → 5 Cl^- (aq) + ClO3^- (aq) + 3 H2O (l)

3 Cl₂ + 6 NaOH → NaClO₃ + 5 NaCl + 3 H₂O
