- The hydroxide concentration is a direct measure of a solution's pH. This may be formed in water/pure water where an acid exist. H3O+ is its chemical formula By combining an H+ion with an H2O molecule, it is formed too.
- The H+ion has a trigonal pyramidal geometry and comprises 1 oxygen atom and 3 hydrogen atoms. There is a single pair of electrons in oxygen that gives it this shape. Between the atoms, the bond angle is around 113 degree. ---- H2O(l)⇌OH−(aq)+H+(aq
- As H+ions are formed, they bond with H2O molecules in the solution to form H3O+(the hydronium-ion). This is due to the hydrogen ions that is not present in aqueous solutions, however takes the form of water H2O

Land degradation is a process in which the value of the biophysical environment is affected by a combination of human-induced processes acting upon the land. It is viewed as any change or disturbance to the land perceived to be deleterious or undesirable.
Land degradation is caused by multiple forces, including extreme weather conditions particularly drought, and human activities that pollute or degrade the quality of soils and land utility negatively affecting food production, livelihoods, and the production and provision of other ecosystem goods and services.
Deforestation is taking place at a faster rate due to increasing demands of timber, fuel and forest products which results into degradation of land resources.
Overgrazing refers to excessive eating of grasses and other green plants by cattle. It results into reduced growth of vegetation, reduced diversity of plant species, excessive growth of unwanted plant species, soil erosion, and degradation of land due to cattle movement.
Following are some practises for controlling land degradation:
1. Strip farming:
It is & practice in which cultivated crops are sown in alternative strips to prevent water movement.
2. Crop Rotation:
It is one of the agricultural practice in which different crops are grown in same area following a rotation system which helps in replenishment of the soil.
3. Ridge and Furrow Formation:
Soil erosion is one of the factors responsible for lad degradation. It can be prevented by formation of ridge and furrow during irrigation which lessens run off.
4. Construction of Dams:
This usually checks or reduces the velocity of run off so that soil support vegetation.
5. Contour Farming:
This type of farming is usually practiced across the hill side and is useful in collecting and diverting the run off to avoid erosion.

Nelson Mandela in his speech on freedom said this words, "freedom is invisible".
According to him, freedom is invisible. Freedom is an abstract idea. The great Rousseau said, "Man is born free but everywhere he is in chains"
And Nelson Mandela says the same. Mandela as a child used to be believe he is always free and in everywhere. But as grew up, he felt the chains of oppression.
Freedom can't be seen rather it is felt. It is like the air. Mandela realized not only he was suppressed, barred but also his people were too. Even the oppressor and oppressed both were suffering from the lack of freedom, according to him.

The postmaster then decided to help Lencho by giving him financial aid. He asks for financial contributions from the employees in the post office. However, he was not able to reach the 100 pesos amount Lencho was asking for. Still he slipped the money in the envelope and signed it God as though God answered Lencho's letter.
