bonds as non-polar covalent, polar covalent, or ionic.

I have 2 chemistry questions that I’m having issues trying to solve.  Can someone please help me?  Thank you

1)  Classify each of the following bonds as non-polar covalent, polar covalent, or ionic. If a bond is polar covalent, identify the atom that has the partial negative charge and the atom that has the partial positive charge. If a bond is ionic, identify the ion that has the negative charge and the ion that has the positive charge.

a. N−O =         d. H−I          g. Se−I             j. F−P

 b. Al−Cl         e. Br−Cl          h. N−Sr

c. Cl−N           f. Cl−S             i. O−F

2)  The soft drinks sold at county fairs are often dispensed from large pressurized

containers that contain carbon dioxide gas above the liquid at a partial pressure

of about 4 atm, compared to carbon dioxide’s normal partial pressure of 0.00035

atm in the air at sea level.

a. Describe the reversible change that takes place inside one of these soft

drink containers when the pressure of CO2 above the liquid is first brought

from 0.00035 atm to 4 atm. Explain why this system comes to a dynamic

equilibrium in which there is no net change in the amount of gas above the

liquid or the amount of gas dissolved in the liquid.

b. Explain why an increase in the partial pressure of CO2 over a liquid leads to

an increase in the solubility of the gas in the liquid.
