i try ... i fail ...

gah x.x
i fail in life .
i swear , i had all of them down .
and i was right too !
i think the answer sheet was wrong or something .
but its better than waiting to see if you got it right or wrong like regular KM , we get out score as soon as we're done .
only if i said CO32- for carbonide instead of Co32-
and NH4+ instead of Nh4+ for Ammonium , i never shouldve changed it .
EFFF!
