Answer 1

Heya☺.


1. Double displacement realction

2. Thermal decomposition reaction

3. Decomposition reaction

4. Electrolytic decomposition

5. Single displacement realction

6. Combination reaction

✌✌Hope this helps !

Answer 2

Answer:

Double displacement reactions

Explanation :

On reaction with the sulphuric acid solution, barium chloride forms a white precipitate of barium sulfate. Double displacement reactions may be defined as the chemical reactions in which one component of each of both the reacting molecules is exchanged to form the products.
