Iron(III) oxide can be reduced by carbon monoxide. Fe2O3(s) + 3CO(g) + 2Fe(s) + 3CO2(g) Use the following thermodynamic data at 298 K to determine the AGº and the equilibrium constant (Key) at this temperature. (10 pts) Substance: AH° (kJ/mol): AG°(kJ/mol): S°(J/K. mol): Fe 0 (9) -824.2 --- 742.2 87.4 CO(g) -110.5 -137.2 197.7 Fe(s) 0 0 27.78 CO2(g) -393.5 -394.4 213.7

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
