Would you be so kind as to help me on these Chemistry problem sets? 
Im having particular issues with the ones below.

Thank you kindly.

01

Of the following pairs of species, which is NOT a Bronsted conjugate
base/acid pair?

a.	NH3: NH4+
b.	C2H3O2-: HC2H3O2
c.	SO2/3-: SO2/4-
d.	C2O2/4-: HC2O4-
e.	O2-: OH-

02

The conjugate acid of HPO2/4- is

a.	H2PO4-
b.	H3PO4
c.	HPO2/4-
d.	H+
e.	PO3/2-

03

These acids are listed in order of decreasing acid strength: HCL, H3O+, HCN
List their conjugate bases in order of decreasing base strength
(strongest base to weakest base).

a.	OH1-, CN1-, CL1-
b.	Cl1-, OH1-, CN1-
c.	CN1-, H2O, CL1-
d.	CN1-, OH1-, CL1-
e.	H2CN+, H4O2+, H2Cl+
f.	Cl1-, H2O, CN1-

04

Based on its dot structure, the best classification for  O2- is as 

a.	an Arrhenius acid
b.	a Bronsted Lowry acid
c.	an Arrhenius base
d.	a Lewis acid
e.	a Lewis base

05

Which of the following is not a Lewis acid?


1.	H+
2.	BH3
3.	Cr+3
4.	HCl
5.	All are Lewis acids

06 

One difference between a Lewis base and an Arrhenius base is

a.	a Lewis base is an electron pair donor and an Arrhenius base is a
proton acceptor
b.	a Lewis base is a proton acceptor and an Arrhenius base produces
hydroxide ions in solution
c.	a Lewis base is an electron pair acceptor and an Arrhenius base is
a proton acceptor
d.	a Lewis base is an electron pair donor and an Arrhenius base
produces hydroxide ions in solution
e.	a Lewis base is an electron pair acceptor and an Arrhenius base is a proton donor
