    The presence of excessive nutrients in the lake due to agriculture run -off from the land, cause the growth of plant life in water body. Fertilizers contain phosphates that increase algae growth in water.
    Algae cover the surface of water, blocking sunlight and depleting oxygen in the water.
    The reduction of oxygen concentration in water causes the death of many aquatic organisms.
    This process of rapid plant growth in water and the depletion of oxygen causing the death of animals results in a disfunctioning ecosystem, called eutrophication.

    Fractional distillation is a technique for the separation of miscible liquids. It is a distillation technique used for the separation of liquids which dissolve in each other. Fractional distillation is a process of separating the components of a mixture by repeated distillations and condensations.
    The principle of fractional distillation is that different liquids boil at different temperature. The miscible liquids boil at different temperature and evaporate at different temperature.
    When the mixture is heated, the liquid with lower boiling point boils and turns into vapours. So the mixture is heated to a temperature at which one or two components of the mixture will vaporise. Fractional distillation involves repeated distillations and condensations.

    When a book is kept on a table its weight acts downwards and presses on the surface of contact of the table. This pressing force acting over the entire area of the surface is called thrust. Thrust is the total force acting perpendicular to the surface. The unit of thrust is Newton. The force acting over unit area is called pressure. The unit of pressure in the SI system is Newton/m2.

    Displacement reaction
    1) a more highly reactive element displaces the less reactive element from its solution form.
    2) generally no precipitate is formed.
    3) eg: 3FeSO4 +2Al  → Al2(SO4)3 + 3Fe
    4) it is a slow reaction
    Double- displacement reaction
    1) the exchange of ions between the two reactant compounds take place. if there is a double displacement reaction taking place then you don’t have to consider the reactivity order.
     2) generally precepitates are formed. note that all neutralisation reactions are double displacement reactions' special case as no ppt is formed.
     3) Pb(NO3)2 + 2KI →  PbI2 + 2KNO3
    4) it is a fast reaction
