I believe that the choices for this question are:
C2H4O2, C4H8O4 <span>
CH2O, C6H12O6
C3H6O3, C6H12O6
C2H4O2, C6H12O6 </span>
The answer to this based on the molar masses given is:
C2H4O2, C6H12O6
To prove calculate the molar mass:
C2H4O2 = 2*12 + 4*1 + 2*16 = 60
C6H12O6 = 6*12 + 12*1 + 6*16 = 180
Answer:
upward (F=ma if f is up a is up)
