what is the pH of a buffer solution containing 0.69M of human tears?

today was the day.

chemistry exam numero dos.

and considering how exam numero uno went...

i was stressed.anxious.nervous.nauseous.

after studying...

{and going to the drive-ins}

i woke up today,

showered and got ready.

because, after all, 

if i was going to fail this test

i was going to look good doing it dangit.

so, now that it's over, 

and my bubble sheet destiny is in the hands of my professor...

i think i might throw up.
