Answer:
A. the intermolecular forces are similar in both dichloromethane and iodine.
Explanation:
Solubility is determined by the principle , "like dissolves like" .
i.e. , if a compound is polar then it will dissolve in a polar compound only , and
if a compound is non - polar then it will dissolve in a non - polar compound only .
As,
Non polar compounds , have similar interaction , and hence gets dissolved , and similarly ,
polar compounds have similar dipole - dipole interaction , and hence gets dissolved .
From the question ,
Iodine, I₂(s), is more soluble in dichloromethane, CH₂Cl₂(l) , as both are non - polar in nature and hence due to similar interaction , are soluble .
Water is polar in nature and therefore less soluble in Iodine, I₂(s) .

Answer:
<h2>hydrogen gas is produced .</h2>
An ideal gas is defined as one in which all collisions between atoms or molecules are perfectly eleastic and in which there are no intermolecular attractive forces. One can visualize it as a collection of perfectly hard spheres which collide but which otherwise do not interact with each other.

The correct answer would be the first option. Material A having a smaller latent heat of fusion would mean that it will take only less energy to phase change into the liquid phase. Latent of heat of fusion is the amount of energy needed of a substance to phase change from solid to liquid or liquid to solid.
