Reactions within equations and properties of acidity

A reaction occurs for each of the following below. How do you differentiate between the different driving forces? (a driving force can either be the transfer of electrons; the formation of a precipitate, etc.)

2Na(s) + 2H2O(l) --> 2NaOH(aq) + H2

KOH(aq) + HF(aq) --> KF(aq) + H2O(l)

NaF(aq) + HCl(aq) --> NaCl(aq) + HF(aq)

Pb(NO3)2(aq) + Na2CrO4(aq) --> PbCrO4(s) + 2NaNO3(aq)

NaNO3(aq) + HCl(aq) --> NaCl(aq) + HNO3(aq)

How exactly would I go about finding which one of the following listed solutions below is the most acidic?

1.0 molar HClO3(aq)
1.0 molar HC2H3O2(aq)
1.0 molar HCN(aq)
1.0 molar HNO2(aq)
1.0 molar HF(aq)

Is HC2H3O2(aq) a strong acid?
