Jan 10, 2017 · 1. O is a singular oxygen atom. O 2 is a molecule made of two oxygen molecules. Our atmosphere is made of mostly O 2, which our bodies have evolved to breathe. We breathe in O 2 and cellular respiration requires it (C 6 H 12 O 6 +6O 2 →6CO 2 +6H 2 O). O is oxygen, while O 2 is dioxygen.
Feb 19, 2021 · 5. According to molecular orbital theory (MOT), OX2X2+ O X 2 X 2 + has a greater bond order than OX2 O X 2 and two less antibonding electrons. So why is molecular oxygen OX2 O X 2 more stable than the molecular ion OX2X2+? O X 2 X 2 +? One possible reason that comes to mind is that the antibonding (AB) orbitals, although higher in energy than ...
May 30, 2017 · 2O 2 O is basically two atoms of oxygen, unbonded and separate. On the other hand, OX2 O X 2 is oxygen molecule, which is more commonly called oxygen gas. Share. Cite. Improve this answer.
Nov 25, 2018 · 1. Diamond and graphite are both arrangements of carbon atoms, each with very different properties and yet they are both pure carbon, as is a single carbon atom, of course. Likewise OX2 O X 2 is as much oxygen as atomic oxygen is. The only complication is that what we habitually think of as oxygen is oxygen as a gas comprised of OX2 O X 2 ...
In the case of the $\ce{N2 + O2 -> 2NO}$ , $\Delta H$ and $\Delta S$ are both positive, so the reaction is thermodynamically favorable at high temperature (such as in lightning) but not at low temperature. If the temperature drops to room temperature after NO is formed, it is thermodynamically favorable for NO to decompose to nitrogen and oxygen.
Jul 18, 2014 · This phenomenon is explained by s-p mixing. All the elements in the second period before oxygen have the difference in energy between the 2s and 2p orbital small enough, so that s-p mixing (combination) can occur lowering the energy of the σ(2s) and σ*(2s) and increasing the energy of the σ(2p) and σ*(2p) molecular orbitals.
So in "first" step: CHX4 +OX2 COX2 +2HX2 C H X 4 + O X 2 C O X 2 + 2 H X 2. but then the hydrogen will be also combusted in reaction : 2HX2 +OX2 2HX2O 2 H X 2 + O X 2 2 H X 2 O. so the overall reaction will be: CHX4 +2OX2 COX2 +2HX2O C H X 4 + 2 O X 2 C O X 2 + 2 H X 2 O. As was pointed out in the others answers the real mechanism of a methane ...
Aug 8, 2012 · $\begingroup$ @GregE. generating oxygen is a separate concern from CO2 removal (i.e. wouter dorgelo's 'providing astronauts with fresh oxygen' ... stated in the context of CO2 conversion to C and O2). Yes, you can generate O2 via electrolysis, but it is the concentration of CO2 and its build-up that creates a hazard for humans.
May 3, 2016 · To understand the paramagnetic nature of $\ce{O2}$, we must first understand how atomic orbitals mix together to form molecular orbitals. In the diatomic molecules of the elements in the second period, a phenomenon known as $\mathrm{s}$-$\mathrm{p}$ mixing results in an increase in the energy of the $\sigma_\mathrm{2p_z}$ molecular orbital, and a decrease in the energy of the $\sigma_\mathrm{2s}$ orbital.
Mar 21, 2017 · The reason you do not need to consider all three terms is the steady-state assumption, which requires that step 1 happens only once (net) per reaction 2. If forward step 1 is faster than step 2, it is offset by the reverse step 1, so that O that is produced in step 1 is consumed in step 2 at the same rate.
