Chemistry

During mid-January 2004, average gas concentrations measured inCache Valley were:
ammonium (NH4) = 16 Âµg/m^3
nitrate (NO3) = 45 Âµg/m^3
NH4 + NO3 = NH4NO3 (s)
a) Is NH4 or NO3 the limiting factor for the formation ofNH4NO3? Explain using appropriate calculations.
b) Calculate the average NH4NO3 concentration (Âµg/m^3) based onthese concentrations.
c) If we could reduce ammonium emissions by 15% by changing thecomposition of cattle feed, but nitrate remained the same,calculate the average NH4NO3 concentration (Âµg/m^3).
d) If we could reduce nitrate emissions by 15% through a vehicleinspection program, but ammonia remained the same, calculate theaverage NH4NO3 concentration (Âµg/m^3).
e) Based on your answers to part c) and d), which pollutant (NH4or NO3) should we target first?
PS. This is an environmental engineering.
