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
The correct answer should be Troy
Answer:k
Explanation:
It’s because in the equator it
recevies direct sunlight so it gets more heat
and also it doesn’t get affected by the earth tilt
hope this helps
and in the North Pole and south pole it doesn’t receve direct sun light and does get affected by the earth tilt
Answer:
Option (C)
Explanation:
Plates here refers to the lithospheric plates, which can be defined as the small or large broken fragments of the earth's crust. These plates constantly moves from one place to another due to the formation of convection current in the mantle. The plates comprises both the oceanic as well as continental crust, which shares three types of distinct plate boundaries such as the convergent, transform and divergent plate boundary.
Thus, the correct answer is option (C).
