Activity:Take a glass jar fitted with 2carbon electrodes.one acts as a cathode the other acts as an anode.Two test tubes are inverted on the carbon rods to collect some gas.They are connected to a6V battery.Now fill the glass jar with 100 ml of acidified water.Now thermal decomposition takes place and releases twice the volume of hydrogen gas and one volume of oxygen gas in the form of bubbles in the test tube.Now carefully take out hydrogen containing test tube and take it near the candle it burns very brightly.In the ratio of 2:1 volumes of hydrogen and oxygen are collected respectively.

Modh Niyati 5 years, 8 months ago

Very easy. Composition of water 2 molecules of hydrogen and one molecule of oxygen. That's why 2:1 ratio.

Chemical reactions can be classified in following types:

  • Combination Reaction

    Example: When magnesium is burnt in air (oxygen), magnesium oxide is formed. In this reaction, magnesium is combined with oxygen.

    Mg + O2  → 2MgO

  • Decomposition Reaction
    Example: When calcium carbonate is heated, it decomposes into calcium oxide and carbon dioxide
    CaCO3  → CaO + CO2
  • Displacement Reaction
    Example: When zinc reacts with hydrochloric acid, it gives hydrogen gas and zinc chloride.Zn + 2HCl  → ZnCl2 + H2

  • Double Displacement Reaction

    Example: When solution of barium chloride reacts with the solution of sodium sulphate, white precipitate of barium sulphate is formed along with sodium chloride.

    BaCl+ Na2SO → BaSO4 + 2NaCl

  • Oxidation and Reduction Reaction

    When sodium hydroxide reacts with hydrochloric acid, it gives sodium chloride and water.

    NaOH + HCl  →  NaCl + H2O

To understand the refraction of light through a glass slab consider the figure given below which shows the refraction of light through a rectangular glass slab.

Here in this figure AO is the light ray travelling in air and incident on glass slab at point O.
Now on entering the glass medium this ray bends towards the normal NN’ that is light ray AO gets refracted on entering the glass medium.
After getting refracted this ray now travels through the glass slab and at point B it comes out of the glass slab as shown in the figure.
Since ray OB goes from glass medium to air it again gets refracted and bends away from normal N1N'1 and goes in direction BC.
Here AO is the incident ray and BC is the emergent ray and they both are parallel to each other and OB is the refracted ray.
Emergent ray is parallel to incident ray because the extent of bending of the ray of light at the opposite parallel faces which are PQ (air-glass interface) and SR (glass-air interface) of the rectangular glass slab is equal and opposite.
In the figure i is the angle of incidence, r is the angle of refraction and e is the angle of emergence.
Angle of incidence and angle of emergence are equal as emergent ray and incident ray are parallel to each other.
When a light ray is incident normally to the interface of two media then there is no bending of light ray and it goes straight through the medium.
