Balanced equation for dehydration of ethanol by hot concentrated sulfuric acid
- The reactants involved in the given reaction is ethanol with the chemical formula
.
- When it is treated with hot concentrated sulfuric acid at 443K, it leads to the formation of ethene and water.
- As the water molecule present in the ethanol is removed, this process is called dehydration.
- As hot concentrated sulfuric acid is used as a catalyst, it is not added in the reactant side.
- The balanced chemical equation involved in the process is as follows:

Abnormally high blood pressure and a combination of high psychological stress are known as Hypertension. These patients suffering from this disorder will have their blood pressure reading greater than 140 over 90 mm.
Hypertension is diagnosed by measuring blood pressure. The Systolic pressure would be the first readings viz. a pressure by which the heart pumps blood through the body, and second readings would be the Diastolic pressure, meaning a pressure at which the heart relaxes and refills the blood.

The peasants joined the Non Cooperation movement because the 'talukdars' and the landlords were demanding high land revenues from them. Peasants had to do 'begar' and work at landlords’ farms without any payment.
The tribals joined the movement because they were denied the rights by the British to collect wood, fuel and fiber from the forests. Most of them were also denied the permission to graze their cattle.
It were because of the above reasons that the peasants and tribals joined the Non Cooperation Movement.

They participated in Gandhiji’s Non-cooperation movement because the colonial government had closed large forest areas, preventing them from entering the forests to graze their cattle, or to collect fruits and fuelwood.

Democracy is a form of government in which the rulers are elected by the people. One chief factor common to all democracies is that the government is chosen by the people. It also helps students to demarcate between democratic and non-democratic governments. From the non-democratic government, take the example of Myanmar, where rulers were not elected by the people. Those who were in charge of the army of the country took over as rulers and people had no say in this decision. Dictators like Pinochet (Chile) are not elected by the people. This also applies to monarchies.
Features of Democracy
The simple definition of democracy gives rise to various questions, which are given below:
- Who are the rulers in this definition?
- What kind of election constitutes a democratic election?
- Who are the people who can elect the rulers or get elected as rulers?
- Finally, what form of government is a democracy?

A rainbow is regarded as one of the most spectacular light shows observed on the earth. Rainbow is a multicoloured arc made due to the striking of light on water droplets. Rainbow is produced after the rain, by reflection, refraction and light dispersion process in droplets of water. All such events develop a light spectrum in the sky are called rainbow.
The necessary conditions for the formation of the rainbow
- Presence of raindrops.
-
Sun should be at your back to observe the rainbow.
Formation of the rainbow:
-
Light rays, reach the drop near its top level. At first, there is refraction, then the dispersion of white light into colours of a different wavelength.
-
The violet is the most deviated and red is the least deviated colour.
-
Reaching the opposite side of the drop, each colour is refracted back into the drop due to the complete internal reflection that hits the drop surface.
-
Every colour is refracted to the air again.
- We experience the rainbow when we observe in between 42-20 degrees.

- A rainbow is a natural spectrum of sunlight in the form of bows appearing in the sky when the sun shines on rain drops.
- It is combined result of reflection, refraction and dispersion of sunlight from water droplets, in atmosphere.
- Always it formed in the direction opposite to the sun.
- To see a rainbow, the sun must behind us and the water droplets falls infront of us.
- When a sunlight enters into a spherical rain¬drop, it is refracted and dispersed. The different colours of light bent in different angles.
- When different colours of light fall on the back inner surface of drop, it (water drop) reflects (different colours of light) internally (total internal reflection).
- The water drops again refracts the different colours, when it comes out from the raindrop.
- After leaving this different colours from the raindrop as rainbow, reach our eye. Thus, we see a rainbow.
