Пояснення:

V(C2H5OH)=30л

V(O2)-?

C2H5OH+3O2=2CO2+3H2O V(C2H5OH):V(O2) 1:3

V(O2)=30×3=90л

The forest is a basis for the existence of many organisms. The forest protects the Earth from erosion, prevents evaporation — in this way it feeds the rivers and serves home for animals. Forest is not only trees. Under the branches of higher trees there are lower trees and then — grass, mushrooms, etc. In this way the density of organisms and its diversity is very high.
Forests are often called ‘the lungs of the planet’. As we know, when man breathes he consumes air containing oxygen and gives out air containing carbonic gas. So the amount of carbonic gas increases. This gas is also educed in the process of burning. But there is a way back. During the photosynthesis carbonic gas turns into oxygen. It’s the forests that do the main part of work turning C02 into 02. This explains their name ‘the lungs of the planet’.
In his activity man needed timber for building and warming his home and fields for growing crops. That’s why for hundreds of centuries forests were disappearing and ecological balance was being changed.
For the first civilisations of people it was difficult to realise the possible danger. Recently the palaeontologists found out that ecological crises happened in ancient times. One of the tribes of the South American Indians - Anasasi — abruptly left its place of living with roads and irrigation systems around 1200 AD. It happened because they had destroyed forests so violently that the latter didn’t replenish on the devastated areas. Similar problems appeared in the 20th century. The only difference was that people started thinking the situation over. That’s when ecology appeared.
It’s extremely important to take care of forests. If the forest is destroyed because of commercial interests, there will be little water and the erosion will start on the slopes. Thus, the productivity of planes will decrease. This shows how important forests are. For the sake of life on the Earth there must be large areas of natural ecosystems.
Our country does much to preserve forests. In 1942 the so-called ‘forests of the first group’ were created. It is illegal to cut them. Still, much depends on the people. Because of them forest fires take place. It will take one hundred years to grow the similar forest on the same place. It’s our task to save natural resources because we are a part of nature, the most reasonable and responsible part. Only if we take care of the Earth, people who’ll live after us will have a clean planet, fit for healthy living.​
