Question

Hey mates plz help me!!!!!!! answer the activity with aim conclusion observation ​

Answer 1

here zinc react with sulphuric acid to produce zinc sulphate and hydrogen gas

here due to evalution of hydrogen gas some bubbles can seen

and since it is exothermic reaction

the conical flask turn hot !

Answer 2

Heyaa☺

Activity 1.3⤵⤵

Aim :- Formation of hydrogen gas by action of dilute HCl on Zinc and testing H2 gas.

Apparatus :- Conical flask,tube,match stick.

Chemicals :- Zinc granules and dil.HCl.

Procedure:-

Take a few granules of zinc in a conical flask.

Add about 5ml of dil.HCl to the conical flask.

Observe the changes in the conical flask.

Dip the red litmus paper in it.

Observation:- Light of burning match stick put off with pop sound.
