. The first half of the phase and the changes in these phases are controlled by estrogens and progesterone. The secretion of these hormones occur cyclically because of the cyclic secretions of pituitary gonadotropins in the female. The fertilised ovum in mammals and other higher animals passes thro..

Pure water being a weak electrolyte under goes self ionization to a small extent as follows: The equilibrium constant for this reaction is: The concentration of unionized water is taken as constant because the degree on ionization of water is very small. So we can write this equat..

>A chemical equation is balanced so that the numbers of atoms of each type involved in a chemical reaction are the same on the reactant and product sides of the equation Equations must always be balanced. Equations are balanced by the hit and trial method. The rate of a chemical reaction depends on..

A set A is said to be a proper subset of set B if A is a subset of B and A is not equal to B. If A is a proper subset of B, then we write A B. In order to show that A B it is sufficient to show that each element of A is in B and there is at least one element in B, which is not in A. Set Operations ..

) to form unionized water molecules. For example, in the reaction between hydrochloric acid and sodium hydroxide ion. The neutralization can be represented a..

. This first space shuttle was launched in 1981. Space Shuttle The permanent manned space station called Mir was launched by the Soviet Union in 1986. Since then many crew have manned this space station and conducted experiments in space. The year 1997 marked the return to the red planet...
