setarakan reaksi CaO (s) + NH4Cl (aq) -> NH3 (g) + CaCl2 (ag) + H2O (l)

CaO + 2 NH4Cl -> 2 NH3 + CaCl2 + H2O

CaO + NH4Cl → NH3 + CaCl2 + H2O

a.CaO + NH4Cl → b.NH3 + c.CaCl2 + d.H2O

→ Ca
a = c

→ O
a = d

→ N
1 = b
b = 1

→ H
4 = 3b + 2d

→ Cl
1 = 2c
2c = 1
c = 1/2

3b + 2d = 4
3(1) + 2d = 4
2d = 4 - 3
2d = 1
d = 1/2

a = c
a = 1/2

1/2CaO + NH4Cl → NH3 + 1/2CaCl2 + 1/2H2O
