Answer : The correct expression for equilibrium constant will be,
Explanation :
Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.
The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.
As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.
The given equilibrium reaction is,
The expression of will be,
Therefore, the correct expression for equilibrium constant will be,

Explanation:
Answer:
- is reused and recycled
- can dissolve more substances than any other liquid
Explanation:
Earth water is reused and recycles in the form of the water cycle (hydrological cycle). In this cycle, water from the earth surface evaporates in the atmosphere, cool and condense into cloud or snow and fall to the earth surface.
As a universal solvent, water can dissolve more substances than any other liquid. The polar arrangement of oxygen and hydrogen atom in the water molecules makes it excellent salt.
On Earth, ~2.5% is a freshwater whereas 97.5% is salt water. The pH of water differs for surface and salt water, i.e. neutral to alkaline respectively. Water molecules attract to other water molecules better than the other substances. Therefore, other options are incorrect.
They rarely occur at molecular levels is incorrect, actually they always occur at molecular levels
