Какой объем этилена при нормальных условиях потребуется для реакции с водой массой 7,2 с , если выход этанола составляет 85 % от теоретического?

DJToxa: Дано:
m(H2O)=7.2г
J=85%
J-выход продукта (этанола)
Найти:
V(C2H4)-?
Решение:
C2H4+H2O--->C2H5OH
M(H2O)=18г/моль
n(H2O)=7.2/18=0.4моль
n(C2H4)=n(H2O)=0.4моль
V(C2H4)=n*Vm=0.4*22.4=8.96л

Ответы

Автор ответа: Диборан

C2H4+H2O=C2H5OH
n(H2O)=m/M=7,2/18=0,4 моль
V(C2H4)=n*Vm=0,4*22,4=8,96 л
P.s.Прошу заметить,что выход продукта,в этой задаче, не влияет на объем этилена.

April 22 is Earth Day. People all over the world think about our planet. They think about air, water, plants and animals on the Earth. They say our planet is in danger. Many people do not know how to protect animal and plant worlds, how to keep the waters clean and the air fresh. But they are ready to do it. They try and help nature.

Water is very important for life on the Earth. It is in oceans, seas, rivers and lakes. There is much water on our planet and at the same time there is little water on it. It is so because very little water on the Earth is good for drinking. In many rivers and lakes water is very dirty. Sometimes people cannot swim even in the sea because the sea and the seaside are not clean. In many places water is not drinkable. It is dangerous to use it when you cook. Even fish die in such water.

For example Lake Baikal is the deepest freshwater lake on the Earth. It is 1741 meters deep. The lake is very beautiful but now it is in great danger, because of the factories which are near it. At some places the water in the lake is so dirty that it can kill animals and plants in Baikal and near it.

The way people live has changed the climate on our planet. Nowadays the temperature is rising. You do not have real Russian winter in Moscow any more. In the north of Europe the climate has become milder and warmer too.

If the temperature grows by 3-4 degrees it will be impossible to live on the planet.

Some people’s activities do a lot of harm to the forests. People cut down trees to build farms, homes and roads. Many animals and plants lose their homes. This is bad for the Earth’s air too. Modern plants and factories send a lot of smoke into air. This is also very bad, because nowadays it’s difficult to breathe in big cities.

So, the problem now is to protect life on the Earth, to save our planet for people.
