Answer:
Explanation: A chemical change is a reaction in which chemical composition of the substance changes. Some bonds are broken and some new bonds are formed.
The reactants are written in terms of their chemical formula on the left hand side and the products are written in terms of their chemical formula on right hand side with a arrow in between. The chemical symbols are followed by their physical states such as (l) for liquid, (s) for solid, (g) for gas and (aq) for aqueous.
Thus the only reaction producing a gas is 
Answer: -
Thus Colligative properties depend most on concentration of solute particles.
Explanation: -
Colligative properties are the properties of a solution that depends only on the number of particles of the solute present in the solution and not on the identity of the solute.
The number of solute particles present per unit volume in a solution is referred to as the concentration of solute particles.
Thus Colligative properties depend most on concentration of solute particles.
