Answer:
The hydrogen gas is prepared in the laboratory required zink granules, dilute sulphuric acid or dilute hydrogen chloride, flask or woulfe’s bottle, and thistle funnel. by the downward displacement of water because it is a gas lighter than water
Reaction:
Zn (s)+2HCl (aq) →ZnCl2(aq)+H2(g)
Zn (s)+H2SO4(aq)→ZnSO4(aq)+H2(g)
The zinc granules are taken in a flask or Woulfe’s bottle and It is connected with the delivery tube to a water trough containing water. Dilute sulphuric acid is poured slowly from the thistle funnel. The hydrogen gas is released and collected in a gas jar by by the downward displacement of water as H2 gas lighter than water

Sheriffs are considered the county official who are most directly responsible for providing public safety. They are the chief law enforcement officer in the district and they have both civil and criminal jurisdiction. They are also in charge of all the investigations of crimes and at the same time they are responsible for implementing court process and orders. The sheriffs and their agencies’ responsibilities differ significantly in every county.
