Verified answer
NaOH + HCl = NaCl + H₂ONaCl + Li = LiCl + Na
2Na + H₂ = 2NaH
NaH + H₂O = NaOH + H₂
NaOH + Li = LiOH + Na
2Na + Na₂O₂ = 2Na₂O
Na₂O + H₂O = 2NaOH
2NaOH + Zn(OH)₂ = Na₂[Zn(OH)₄]
Na₂[Zn(OH)₄] + 2HCl = 2NaCl + ZnCl₂ + 2H₂O
Na₂O + H₂O = 2NaOH
2NaOH + CO₂ = Na₂CO₃ + H₂O
Na₂CO₃ + 2HNO₃ = 2NaNO₃ +CO₂ + H₂O
2NaNO₃ = 2NaNO₂ + 3O₂
