Introduction, Definition, Types OF Ecosystem:- 1.On the Basis OF Formation 2.On the Basis OF Stability 3.On the Basis OF Size, Aquatic Ecosystems:- A. Lakes B.Oceans, Thermal Stratification in Lakes.

"F"_(2) dihybrid ratio 12 : 3 : 1 is explained on the basis of:

The rate constant of a reaction is 3 xx 10^2 "min"^(-1) . What is its order of reaction ? (On the basis of units of rate constant)

Consider the following statement with respect to ecosystems: A. Two basic categories of ecosystems are pond and the grassland. B. Forest, grassland and desert are some example of terrestrial ecosystems. C. Crop fields and an aquarium may also be considered as natural ecosystems: D. Pond, lake, wetland, river and estuary are some example of aquatic ecosystems. Of the above statements:

On exposure to air, alkali metals get tranished due to formation of oxides, hydroxides and carbonates on their surface. When heated in air or oxygen they burn vigourously forming different types of oxides depending upon the nature of the metal. The formation and stability of these metals can be explained on the basis of size of alkali metal ion and the anion. Peroxides are colourless, while superoxides are coloured. The normal oxides are basic while peroxides and superoxides act as oxidising agents. Oxone is
