Beyond the planet Neptune is found a region filled with icy bodies. This region is known as the Kuiper Belt. This holds trillions of objects which is said to be remnants of the early solar system. The region contains comets and dwarf planets.
So in a chemical change, the product would loses its properties, would form new products and would not be easily reversed.
In a physical change, the products WILL NOT lose any of their properties, WILL NOT form any new products and WILL be easily reversed.
Talking about Water turning to ice I would say it’s all about physical change and not chemical change.
But I would suggest you to either make a research about it or ask your teacher :))
Diatomic molecules are the molecules that you can find them in natural bonded to itself. example: O₂, N₂ or Br₂.
the answer is hydrogen ---> H₂
I have attached a little trick to remember these.
Answer: Option (C) is the correct answer.
Explanation:
As the given reaction is as follows.

According to Le Chatelier's principle, any disturbance caused in an equilibrium reaction will shift the equilibrium in a direction that will oppose the change.
Hence, in order to favor the formation of products when we remove
then there will occur decrease in it's concentration.
As
is forming on the product side and equilibrium will shift in the direction where there is less stress.
Hence, then equilibrium will shift in the forward direction, that is, on the products side.
Thus, we can conclude that removing
as it is formed would force the reaction to favor the products.
