Question

Complete the equations given below.
(a) Magnesium + Oxygen
(b) Magnesium oxide + Water
(c) Copper sulphate + Iron
(d) Carbon dioxide + Lime water​

Answer 1

Answer:

2Mg+02 = 2MgO

2Mg+02 = 2MgOMgO+H2O = Mg(OH)2

2Mg+02 = 2MgOMgO+H2O = Mg(OH)2CuSO4+Fe = FeSO4 + Cu

2Mg+02 = 2MgOMgO+H2O = Mg(OH)2CuSO4+Fe = FeSO4 + CuCO2+CaO = CaCO3

Answer 2

Answer:

(a) Magnesium+ Oxygen= Magnesium oxide

(b) Magnesium oxide + water = Magnesium hydroxide

(c) Copper Sulphate+Iron = Iron sulphate+ Copper

(FeSO4) (Cu)

(Green) (Brown)

(d) Carbon dioxide+Limewater=Calcium carbonate

+Water

(CaCO3) (H2O)
