(A.) caco3------>cao+co2 (UN)
B.R➡caco3------>cao+co2

(B.) c+o2--------->co2 (UN)
B.R➡c+o2------->co2

(C.)Cao+h2o------>ca(oh)2 (UN)
B.R➡cao+h20---->ca(oh)2

(d.)Al+cl2-------->Alcl3 (UN)

Answer 2

Answer :

(a) Calcium carbonate  → Calcium oxide + Carbon dioxide

The symbolic representation be

CaCO₃  → CaO + CO₂

Number of Calcium atoms = 1 in each side

Number of Carbon atoms = 1 in each side

Number of Oxygen atoms = 3 in each side

Hence, the balanced equation is

CaCO₃  → CaO + CO₂

(b) Carbon + Oxygen → Carbon dioxide

The symbolic representation be

C + O₂ → CO₂

Number of Carbon atoms = 1 in each side

Number of Oxygen atoms = 2 in each side

Hence, the balanced equation is

C + O₂ → CO₂

(c) Calcium oxide + Water → Calcium hydroxide

The symbolic representation be

CaO + H₂O → Ca(OH)₂

Number of Calcium atoms = 1 in each side

Number of Oxygen atoms = 2 in each side

Number of Hydrogen atoms = 2 in each side

Hence, the balanced equation is

CaO + H₂O → Ca(OH)₂

(d) Aluminium + Chlorine → Aluminium chloride

The symbolic representation be

Al + Cl₂ → AlCl₃

In left hand side,

Number of Aluminium atoms = 1

Number of Chlorine atoms = 2

In right hand side,

Number of Aluminium atoms = 1

Number of Chlorine atoms = 3

Hence, the balanced equation is

2Al + 3Cl₂ → 2AlCl₃

(e) Iron + Sulphur → Iron sulphide

The symbolic representation be

Fe + S → FeS

Number of Iron atoms = 1 in each side

Number of Sulphur atoms = 1 in each side

Hence, the balanced equation is

Fe + S → FeS
