How will the following situations affect the final calculation of the molarity of HC2H3O2?

A small amount of vinegar adhering to the side of the flask was left unreacted when the endpoint was thought to have reached.
After rinsing any drops of vinegar adhering to the side of the flask, another 20 mL of deionized water was added to the vinegar in the falsk.
An air bubble was present in the tip of the buret when making the initial volume reading, but not when making the final volume reading.
The endpoint of the vinegar titration was surpassed (excess NaOH was added).
After the standardization of the NaOH solution using solid H2C2O4•2H2O, the molar mass of anhydrous oxalic acid was used to calculate the molarity of the NaOH solution.
