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

That is true the hemisphere that is tilted towards the sun receives more direct sin light. So it must be right
The correct answers are:
- Formation 2 is an intrusion;
- Formation 1 in an extrusion;
- Formations 1 and 2 are igneous rocks;
The formation one on this image is an extrusion, and the reason why it is an extrusion is that it has come out on the surface. The formation two on this image is an intrusion, and the reason why it is an intrusion is that it has formed deep into the ground.
Both of the formations will produce igneous rocks. The formation one will produce extrusive igneous rocks that will have very small crystals because of the quick cooling off of the magma. The formation two will produce intrusive igneous rocks that will have larger crystals because of the slower cooling off of the magma.
