What element is being reduced in the following redox reaction? C 5H 12O 2( aq) + NaMnO 4( aq) → C 5H 6O 4Na 2( aq) + MnO 2( aq)
C
Na
O
Mn
H

Which of the following processes shows a decrease in entropy of the system?
2 CO(g) + O2(g) → 2 CO2(g)
COCl2(g) → CO(g) + Cl2(g)
CH3OH(l) → CO(g) + 2 H2(g)
NaClO3(s) → Na+(aq) + ClO3-(aq)
None of these will show a decrease in entropy.
