Acids in water solution dissociates H+ ions. Let us consider the reaction between water and hydrochloric acid (HCl). HCl in presence of water produces H+ ion. This ion cannot exist alone and hence combines with water molecules and forms H3O+. The reaction is as follows:
Base when dissolved in water produces OH- ion. Let us consider the reaction between water and sodium hydroxide NaOH. NaOH in presence of water produces OH- ion.
Therefore the neutralisation stands out as follows:

The term 'foreigner' is used in the sense of a person who is not an Indian. In the medieval period it was applied to any stranger who appeared, say in a given village, someone who was not a part of that society or culture. In this sense a forest-dweller was a foreigner for a city-dweller. But two peasants living in the same village were not foreigners to each other, even though they may have had different religious or caste backgrounds.

3(b+4)—7=4b+14
3b + 12 - 7=4b + 14
3b + 5 = 4b + 14
3b - 4b = 14 - 5
-b = 9
b = -9

S.I = P × r × t/100
here, P = 212.50 Rs.
r = 3 % and t = ?
so, S.I = 212.50× 3 × t/100
= 637.5t/100
= 127.5t/20
=25.5t/4
now, you can see that , Simple interest will be exact number of rupees when t = 8,16

Animals often adapt themselves to the climatic conditions in which they are living. For example, a polar bear has a thick skin and a layer of fat and is adapted for Polar Regions. These conditions keep the animal warm.
