Answer 1

Answer: All the molecular reaction and ionic equation are written in the image attached:

Observations of all the reaction:

5) when barium chloride is mixed with sulphuric acid , white precipitate of barium sulfate will be produced . This is double displacement type reaction

In this case , predicted and experiment observation both are same .

6) when ammonium hydroxide (weak base) is mixed with sulphuric acid , neutralisation reaction takes place and leads to generation of heat , by which overall solution become somewhat hot .

Also, in this case predicted and experimental observations are same.

7) Predicted: When copper sulphate is mixed with Zinc nitrate , Zinc sulphate and Copper nitrate should produced.

Experimental : As both the salt produced are soluble in water , so there is no evidence that reaction is taking place or not .

8) When sodium carbonate and calcium chloride are mixed , white colour precipitate of Calcium carbonate produced .

In this case , both predicted and experimental observations are same .

9) Predicted : When Copper sulphate solution is mixed with ammonium chloride solution , ammonium sulfate and copper chloride will be produced

Experimental : As both the produced salt are dissolved in water , so there is no evidence that reaction is taking place or not.

10) When sodium hydroxide is mixed with nitric acid , neutralisation reaction takes place which generate heat , so Solution becomes hot .

In this case predicted and experimental observations are same.

11) When Ferric chloride solution is mixed with ammonium hydroxide solution , reddish brown precipitate of Iron(III) hydroxide will be produced .

In this case predicted and experimental observations are same.

12) When solid Sodium sulphite is mixed with Hydrochloric acid , SO_{​​​​​2} gas will be produced , which smells like rotten egg.

also in this case predicted and experimental observations are same.
