Question

which of the following are combination reactions? (i) 2KClO3 ⎯⎯⎯⎯ Heat → 2KCl + 3O2 (ii) MgO + H2 O ⎯→ Mg(OH)2 (iii) 4Al + 3O2 ⎯→ 2Al2 O3 (iv) Zn + FeSO4 ⎯→ ZnSO4 + Fe (a) (i) and (iii) (b) (iii) and (iv) (c) (ii) and (iv) (d) (ii) and (iii)

Answer 1

option (d) (ii),(iii) is correct
Hope it helps you

Answer 2

Hey here is Ur answer

D ) is the ryt answer

means equation ( ii ) and ( iii ) are combination relations

BcZ i) is the decomposition reaction
and iv) is the displacement reaction

Therefore D) is the ryt answer...
