Write the word equation for the reaction of barium nitride with potassium

Barium nitride + potassium → potassium nitride + Barium.

Explanation:

The word equation is a chemical equation expressed in words rather than the conventional chemical formula. The word equation represent a chemical reaction of elements or compounds in words. The reactants are represented in words and the product sides are represented in words. The arrow is also included.

The reactions is as follows:

Barium nitride + potassium → potassium nitride + Barium.

The reaction is a displacement reaction. Potassium is more reactive metal than Barium, so it will displace a less reactive metal ion from it compound. The chemical reaction between barium nitride and potassium will produce potassium nitride and barium.

The balanced chemical equation using chemical formula is as follows:

Ba3N2 + 6K → 2K3N + 3Ba

Well this is a metathesis or partner exchange reaction ... and barium sulfate is as soluble as a brick ...

Explanation:

And so ...

Ba (NO3) 2 (aq) + K2SO4 (aq) →2KNO3 (aq) + BaSO4 (s) ⏐↓

Note that you simply HAVE TO KNOW that barium sulfate is insoluble ... as is lead sulfate, and as is (less so) calcium sulfate
