How many of the following are oxidation-reduction reactions? NaOH + HCl $\to$ NaCl + H₂O Cu + 2AgNO₃ $\to$2Ag + Cu(NO₃)₂ Mg(OH)₂ $\to$ MgO + H₂O N₂+ 3H₂ $\to$ 2NH₃

Quizplus · Accepted Answer

The following reactions are oxidation-reduction (redox) reactions:
- Cu + 2AgNO3 -> 2Ag + Cu(NO3)2
- Mg(OH)2 -> MgO + H2O
Therefore, there are 2 redox reactions out of the 4 given.
