Answer:
Step-by-step explanation:
Pb(OH)2 + 2NaOH → Pb(OH)2 + 2NaOH
The balanced equation would be PbO + 2NaOH → Pb(OH)2 + Na2O
The reactant PbO is a lead oxide which is an acidic oxide, it reacts with NaOH, a strong base, to form Pb(OH)2, a lead hydroxide, which is a salt of lead, and Na2O which is sodium oxide , a base.
