Nita Sharma 5 years, 11 months ago

Because blue light ki wave length bhot less hoti h isliye easily scatter hoti hai

1Thank You

Raj Bhagat 5 years, 11 months ago

Due to scattering of light

1Thank You

Yogita Ingle 5 years, 11 months ago

The molecules of air and other fine particles in the atmosphere have smaller size than the wavelength of visible light. These are more effective in scattering light of shorter wavelengths at the blue end than light of longer wavelengths at the red end. The red light has a wavelength about 1.8 times greater than blue light. Thus, when sunlight passes through the atmosphere, the fine particles in air scatter the blue colour (shorter wavelengths) more strongly than red. The scattered blue light enters our eyes.

Isotopes discovered long after Mendeléev periodic classification of
elements imparted a challenge to Mendeleev’s Periodic Law.
The atomic masses of elements did not increase in a steady manner while going from one element to other which made it difficult to predict the number of elements that could be discovered between two elements.

What is thermite teaction

Posted by Chetri Bolt 6 years ago

CBSE > Class 10 > Science

Yogita Ingle 5 years, 11 months ago

The thermite reaction is the reaction of metal oxide with the aluminium. The aluminium acts as a reducing agent and the reaction is highly exothermic and hence called a thermite reaction.

The aluminium reduces the oxide of another metal, most of the times, it is iron oxide (FeO) because aluminium is highly reactive. The reaction involved can be shown as:

Fe₂O₃ + 2Al → 2Fe + Al₂O₃

How galvanised articles is protected against rusting even if zinc coating is broken ?

Posted by Rakesh Kumar 6 years ago

CBSE > Class 10 > Science

4 answers

Akhifa Sheik 6 years ago

Zn is more reactive than Fe and can be oxidised easily. Therefore galvanised articles are protected against rusting even if Zn coating is broken.

Akanksha Kumari? 6 years ago

continue *coating

0Thank You

Yogita Ingle 6 years ago

If the zinc coating is broken, the galvanized object remains protected against rusting because zinc is more reactive than iron and hence can be easily oxidized. Thus when zinc layer breaks down, the zinc continues to react and get oxidized. Hence iron object is protected.

0Thank You

Akanksha Kumari? 6 years ago

Galvanised articles are protected against rusting even if zinc continue is broken because zinc is more reactive than iron hence it reacts with oxygen in air and forms zinc oxide . This oxide layer prevents further rusting of iron article.
