Question

Select the correct classification for the reaction.

CaCl₂(aq) + Li₂SO₄(aq) → 2LiCl(aq) + CaSO₄(s)

A.single-displacement

B.double-displacement

C.combination

D.decomposition

combustion

Answer 1

Combination: For this type of reaction there is only 1 product formed from 2 or more reactant

Decomposition:For this type of reaction there is only 1 reactant and decomposes into 2 or more products

single displacement: In this type, 1 reactant displaces other reactant from its compound

double displacement:In this type, both reactant displaces each other

combustion reaction: compound reacts with O2 to give CO2 and H2O

Here both the anions are getting displaced.
Anion Cl- is displaced from Ca2+ to Li+
Anion SO42- is displaced from Li+ to Ca2+

So, this is double displacement reaction

Answer: B
