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
Dams are important because:
They provide water for domestic, industry and irrigation purposes.
Dams often also provide hydroelectric power production and river navigation.
Domestic use includes everyday activities such as water for drinking, cooking, bathing, washing, and lawn and garden watering.
Dams and their reservoirs provide recreation areas for fishing and boating.
They help people by reducing or preventing floods. During times of excess water flow, dams store water in the reservoir; then they release water during times of low flow.
In a region that has a humid continental climate, the animals and plants living there should have some specific adaptations in order for them to survive without any bigger problem in the environment.
The animals have thicker fur which is also waterproof, in order to keep them warm, and to not allow that they are wet and heavy because of the common rains. They also tend to develop and even thicker winter coat in order for them to survive the cold snowy winters.
The plants tend to shed their leafs in the autumn as they put themselves in a hibernation mode for the cold winter, and then grow them again in the spring for the vegetative season in the coming months. They tend to be plants that manage to consume large amounts of water, but also can restrict the amount of water, as the evaporation is not as high in this parts, so they have to limit the water in order to not over-saturate themselves.
