Verified by ExpertsCHECK THE SOLUTION.
(i) K 2 O + H 2 O 
KOH
K 2 O 2 + H 2 O 
KOH + H 2 O 2
KO 2 + H 2 O 
KOH + H 2 O 2 + O 2
KO 3 + H 2 O 
KOH + O 2
Be 2 C + H 2 O 
CH 4 + Be(OH) 2
Mg 2 C 3 + H 2 O 
CH 3 –C 
CH + Mg (OH) 2
CaC 2 + H 2 O 
Ca(OH) 2 + C 2 H 2
MCO 3 
MO + CO 2 (M : alkaline earth metal )
NaOH + CO 2 
Na 2 CO 3 + H 2 O
NaOH + NO 2 
NaNO 2 + NaNO 3 + H 2 O
NaOH + SO 2 
Na 2 SO 3 + H 2 O
(ii)
(iii) H 2 O + CO 2 ⎯→ H 2 CO 3
H 2 O + NO 2 ⎯→ HNO 2 + HNO 3
H 2 O + SO 2 ⎯→ H 2 SO 3
