The coloured dye in litmus will get adsorbed on the surface of charcoal so, i.e. why the litmus solution becomes colorless.

Devil ? 4 years, 8 months ago

Due to adsorption

Gaurav Seth 4 years, 8 months ago

ANSWER
When a solution of acetic acid in water is shaken with charcoal, a part of the acid is adsorbed by the charcoal and the concentration of the acid decreases in the solution. Similarly, the litmus solution when shaken with charcoal becomes colourless.

Most of the reaction of fluorine is exothermic because fluorine in its elemental state is considered to be electronegative element in the periodic table of all the elements.

The reaction of fluorine always helps in producing a huge amount of energy with the production of oxygen and water.

Therefore, fluorine is exothermic.

Due to high UV radiation

Yogita Ingle 4 years, 8 months ago

The ozone formation is actually endothermic, and oxygen is known to be less stable when combined with Heat as in speaking from the basis of thermodynamically. This is because oxygen decomposes in Ozone and then the Heat is liberated. Adding to this, Ozone is known to consist of 3 molecules of oxygen and is in an unstable state and is known to give out one molecule of oxygen for restoring a diatomic state. So basically immense quantities of Heat are released from this reaction, and the same is released to the atmosphere.

When salt is spread over snow covered roads, snow starts melting from the surface because depression of freezing point of water takes place due to addition of salt. It helps in clearing of roads. Hence, the phenomena is depression in freezing point which helps in clearing the snow covered roads in hilly areas.

A substance which do not show same properties in all direction or (all axis) is called anisotropy substance. Properties like as Electrical Resistance, Refractive index, etc

Gaurav Seth 4 years, 8 months ago

 Anisotropy:-

  • Due to regular arrangement of constituent particles, the different particles are fall in different ways of a crystalline solid. The values of properties like electrical conductivity and thermal expansion not remains same in all the direction this is called anisotropy.
