Questions tagged [atmospheric-chemistry]

Chemical reactions that occur in the atmosphere of Earth and other planets. Relevant reactions include both those that take place only in the gas-phase, in the solid or liquid phases of aerosols or any reactions between the phases as well as the thermodynamics of the phase changes that take place in the atmosphere.

Curious about the chemistry of Carbon-14 after it's produced in the atmosphere

It's often explained how $\ce{^14C}$ is formed in the upper atmosphere, a neutron hits a nitrogen atom and ejects a proton. Source. Since this is likely to happen to an $\ce{N2}$, I'm curious what the chemistry that follows is. Does the energy of…

How chemically homogeneous is air?

By this, I mean if I buy compressed dry air from somebody like British Oxygen how much variation in composition might I expect between batches? For example, is Argon evenly distributed globally, by height, by geography etc? Is $\ce{CO2}$ removed?…

Why is oxygen an anomaly in this context?

In A Very Short Introduction: Earth System Science by Tim Lenton, the author discusses the composition of atmosphere: the first observations from land-based telescopes showed that Mars had an atmosphere dominated by carbon dioxide, just as would be…

How to calculate the abundances of certain gases from the peak areas, GC-MS

In an experiment we had a series of air samples which were analysed through GC-MS, before using TargetLynx software to integrate the mass spectrum obtained. So I now have the specific peak areas for a number of compounds (for example CFC-12 has an…

Does a live electrical wire change the surrounding atmospheric chemistry?

Background: I'm world building an Earth-like world for a writing project. One of the goals of this project is to talk about changes in atmospheric chemistry across multiple scales ('nano'-scale through the entire atmospheric air column). My project…

How to calculate atmospheric composition

Okay, so I'm a novice in chemistry and am trying to figure something out. Say that you want to turn carbon dioxide into oxygen using photosynthesis, given an infinite supply of water. Say that the atmosphere's volume is 100km^3 and has a pressure of…

Why does NO have a residence time of 4 days?

If $\ce{NO}$ is unstable, why does it have an atmospheric lifetime of 4 days? I know that it has a lone pair and one unpaired electron making it highly reactive. Therefore, shouldn't it react immediately in the atmosphere?

How is O3 GHG gas created by human activity causing climate change?

Please help me undestand these. Greenhouse gases from human activity directly are: $\ce{CO2}$, $\ce{CH4}$, $\ce{NO2}$, $\ce{O3}$, and the $\ce{F}$-gases. Wikipedia agrees: https://en.wikipedia.org/wiki/Greenhouse_gas It is clear that $\ce{CO2}$ and…
