Question

Identify the combination reaction in the following:
(a) NH3 + HCI → NH4 CI
(b) NaCI + KOH → NaOH + KCI
(c) 2KCIO3 → KCI + 3O2
(d) NH3 + HCI → NH4CI

Answer 1

Answer:

a and d are correct answer

Explanation:

NH3 + HCl form NH4Cl

Answer 2

The combination reaction in the following is (a) and (d).

Explanation:

Combination reaction is a type of chemical reaction which combines two or more elements to produce a compound; it also combines an element and a compound to produce a different compound.

The general equation of the combination reaction is:

$\bold{X + Y \longrightarrow XY}$

From the question, in option (a) and (d), the ammonium and hydrochloric acid combines to form ammonium chloride.

Option (b) is an example of double displacement reaction.

Option (c) is an example of decomposition reaction.
