30 points which of the following are properties of ionic compounds? i. very soluble in water ii. consist of molecules iii. low melting points iv. exist as crystalline solidsi & & ivii & & iv

Answer : The correct option is, I & IV

Explanation :

Ionic compound : Ionic compound are the compounds which are made up of ions. These ions are held together by the electrostatic force of attraction between the oppositely charged ions.

Properties of ionic compounds :

Therefore, the option (I) and (IV) are the properties of ionic compounds.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

can you list the answers so i can answer
