One of the steps in the commercial process for converting
ammonia to nitric acid is the conversion of NH3 to NO:
4NH3(g)+5O2(g)→4NO(g)+6H2O(g)
In a certain experiment, 1.20 g of NH3 reacts with 2.20 g of
O2.

numerically separated by a comma.
b) How many grams of the excess reactant remain after the
limiting reactant is completely consumed? Express your answer in
grams to three significant figures.

One of the possible initial steps in the formation of acid rain
is the oxidation of the pollutant SO2 to SO3 by the following
reaction: SO2(g) + 1/2 O2(g) -> SO3(g) The reaction is
exothermic, meaning that it is spontaneous at lower temperatures,
but becomes nonspontaneous at higher temperatures. At what
temperature does it change from being spontaneous to
nonspontaneous?

Ammonia gas enters the reactor of a nitric acid plant mixed with
30% more dry air than is required for the complete conversion of
the ammonia to nitric oxide and water vapor. If the gases enter the
reactor at 75 ◦ C (167 ◦ F), if conversion is 80%, if no side
reactions occur, and if the reactor operates adiabatically, what is
the temperature of the gases leaving the reactor? Assume ideal
gases.
Calculate the pH. Please show steps.

Imagine that in a metabolic pathway, one of the steps involves
the oxidation of saturated compound to an unsaturated compound,
with the concomitant reduction of the cofactor FAD to FADH2 as
shown below:
R-CH2-CH2-R' + FAD
<----> R-CH=CH-R'
+ FADH2
Imagine further that ΔG°´ for this reaction is 0 kcal/mol. Given
this scenario, what would be the equilibrium concentration of FADH2
(expressed in mM to the nearest tenth of a unit) if a biochemist
started with a...
Ammonia is burned to form nitric oxide in the following
reaction: NH3 + O2 NO + H2O
(i) Determine if the above stoichiometric equation is balanced
and calculate the ratio of kmol NH3 react/kmol NO formed
