See Explanation

Explanation:

The ionic compounds are; MnSO4 and LiF

The covalent compounds are; CH3NH2, PCl5 and O2

1) The formulas of the ions are;

MnSO4  - Mn^2+ SO4^2-

LiF - Li^+ F^-

The structure of each of the three covalent molecules is shown in the images attached to this answer.

2) CH3NH2 - Has a tetrahedral molecular geometry and electronic geometry

PCl5 - Has a trigonal bipyramidal molecular geometry and electronic geometry

O2 - Has a linear molecular geometry and electronic geometry.

3) CH3NH2  is sp3 hybridized

PCl5 is sp3d hybridized

O2 - is sp2 hybridized

4) MnSO4  - Manganese  II sulphate

PCl5 - Phosphorus pentachloride

O2 - Oxygen molecule

LiF- Lithium fluoride

5) PCl5 - Five sigma bonds and no pi bond

CH3NH2 - 6 sigma bonds and no pi bond

O2 - 1 sigma bond and 1 pi bond

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.
