1) 2NO(g) + O2(g)2NO2(g)
Using standard absolute entropies at 298K, calculate the entropy change for the system when 1.83 moles of NO(g) react at standard conditions.
S°system = J/K
2) 2NO(g) + 2H2(g)N2(g) + 2H2O(l)
Using standard absolute entropies at 298K, calculate the entropy change for the system when 1.95 moles of NO(g) react at standard conditions.
S°system = J/K

Consider a culture medium on which only gram-positive organisms such as staphylococcus aureus colonies can grow due to an elevated nacl level. a yellow halo surrounds the growth, indicating the bacterium fermented a sugar in the medium, decreasing the ph as a result and changing the color of a ph indicator chemical. this type of medium would be referred to as a differential and enrichment culture.
