Question

In the given set up hydrogen gasis prepared by adding dil.sulphuric acid to zinc granules:1) Write a balanced chemical equation for the reaction taking place in the flask
1) Name the method of collection of hydrogen gas
3)Mention one phycially property of hydrogen that you can be deduced through this method of collextion
Please answer it fast and please write complete answer

Answer 1

Answer:

1) $Zn$ + $H_{2} SO_{4}$ --->  $ZnSO_{4}$ + $H_{2}$

2) The method for the collection of hydrogen gas is downward displacement of water.

3) The one physical property of hydrogen that can be deduced through this method of collection is that it is highly insoluble in water so therefore it is collected through the downward displacement of water.

hope it helps. :)
