Indicate what type, or types of reaction ech of the following represents:
(a)h2o + c -> co + h2
(b)2kclo3 -> 2kcl + 3o2
(c)al(oh)3 + 3hcl -> albr3 + 3h2o
(d)pb(no3)2 + h2so4 = hno3 + pbso4

a) Single displacement reaction

b) Decomposition reaction

c) Double displacement reaction

d) Precipitation reaction

Explanation:

(a)

In this reaction, oxygen is replaced by C, so it is a type of displacement reaction. Here, only one species is being replaced, therefore, it is a single displacement reaction.

(b)

In this reaction, potassium chlorate decomposes to potassium chloride and oxygen, so it is a type of decomposition reaction.

(c)

In this reaction, chloride and OH- ions are being replaced. so, it is a type of double decomposition reaction.

(d)

In this reaction, is precipitated, so it is a type of precipitation reaction.
