Chapter 12, Problem 104A

Interpretation Introduction

Interpretation:

The type of the reaction needs to be determined.

Concept introduction:

By seeing the products and reactants one can define the type of reaction.

Answer to Problem 104A

Correct answer: Double displacement reaction

Explanation of Solution

Given: $K_{2}C{O}_3+BaC{l}_2\left(aq\right)\to 2KCl\left(aq\right)+BaC{O}_3\left(s\right)$

Reason for correct option: A double displacement reaction occurs when parts of two ionic compounds are exchanged with one another and making two new compounds. As here also in the reaction the ions are exchanged and the product barium carbonate formed is precipitate so it is a double displacement reaction.

Conclusion

Reasons for incorrect options: If one see reaction it can be seen that compounds are exchanged and new compounds are formed which is not the property of combustion, single replacement, and synthesis.
