a) natri hidroxit + sắt(III)clorua →sắt(III)hidroxit + natri clorua

3 NaOH + FeCl₃ → Fe(OH)₃ + 3 NaCl

b) canxi hidroxit + nhôm nitrat → nhôm hidroxit + canxi nitrat

3 Ca(OH)₂ + 2 Al(NO₃)₃ → 2 Al(OH)₃ + 3 Ca(NO₃)₂

c) axit sunfuric + bari hidroxit → bari sunfat + nước

H₂SO₄ + Ba(OH)₂ → BaSO₄ + 2 H₂O

d) Axit sunfuric + Canxi cacbonat → canxi sunfat + khí cacbon dioxit+ nước

H₂SO₄ + CaCO₃ → CaSO₄ + CO₂ + H₂O

e) nito + oxi → đi nito penta oxit

2 N₂ + 5 O₂ → 2 N₂O₅  [Thêm điều kiện t^o ở phản ứng này nữa nha]

Cảm ơn anh ạ
