Uncovering the Mystery of NO Production in Bomb Calorimeter Experiments

  • Thread starter haisol
  • Start date
In summary, during an experiment using a bomb calorimeter to measure the energy equivalent of benzoic acid, the presence of NO (nitrogen monoxide) was detected. The experimenter is unsure of where the NO came from, as the oxygen bomb was isolated from the air and there was no nitrogen present. The TA suggested it could be carbon monoxide instead.

Hello~

I had an experiment, and it was calorimeter measurement.

We used bomb calorimeter to measure the energy equivalent of benzoic acid(C6H5COOH).

We put the benzoic acid pallet into oxygen bomb with 15bar of oxygen.

But, my TA said that NO(nitrogen monoxide) will be produced, and we should find out

where it came from, but I have no idea.

Oxygen bomb was isolated from the air, and there's no nitrogen... where it came from?

Thank you!

That is strange, the NO could not have been created from nothing. How was the bomb constructed, and are you sure it was just benzoic acid and pure oxygen? Any chance he meant Carbon Monoxide?
 

FAQ: Uncovering the Mystery of NO Production in Bomb Calorimeter Experiments

Where does the NO in the atmosphere come from?

The majority of NO in the atmosphere comes from human activities such as transportation, power plants, and industrial processes. However, natural sources such as lightning and microbial processes also contribute to NO levels.

Why is NO important to study?

NO is important to study because it is a key component of air pollution and can have negative effects on human health and the environment. It also plays a role in the formation of other pollutants such as ozone and particulate matter.

How does NO form in the atmosphere?

NO is formed in the atmosphere through a process called atmospheric nitrogen fixation, where nitrogen from the air combines with oxygen to form NO. This process is primarily driven by high energy events such as lightning and combustion processes.

Can NO levels be reduced?

Yes, NO levels can be reduced through various methods such as implementing stricter emission standards for vehicles and industrial processes, using cleaner energy sources, and improving air pollution control technologies. Additionally, reducing individual transportation and energy consumption can also help decrease NO levels.

What are the effects of high NO levels on human health?

Exposure to high levels of NO can irritate the respiratory system and worsen respiratory conditions such as asthma. It can also contribute to the formation of smog and acid rain, which can have negative impacts on the environment and ecosystems.
