2017年1月9日 · What is the difference between $\ce {O}$ and $\ce {O2}$. If C is carbon and then why $\ce {O2}$ is oxygen.

2017年5月30日 · I just saw something in a chemistry lesson what got me confused. What is the difference between $\\ce{2O}$ and $\\ce{O2}$? Thanks for the help!

2016年5月3日 · Paramagnetic molecules are molecules that have single electrons. When I draw the lewis structure of $\\ce{O2}$, it appears to be a diamagnetic structure. What makes it paramagnetic?

2014年7月18日 · 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 …

2014年3月7日 · I think you are confusing something here: Molecular oxygen is most commonly found as the gas we know, $\ce {O2}$ and ozone, $\ce {O3}$. However, this doesn't limit it to only that. …

In this case, the enthalpy of $484\ \mathrm {kJ}$ is released when $2\ \mathrm {mol}$ of hydrogen gas react with $1\ \mathrm {mol}$ of oxygen gas to form $2\ \mathrm {mol}$ of gaseous water: $$\ce …

2018年11月25日 · Likewise $\ce {O2}$ 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 $\ce {O2}$ molecules. …

2021年2月19日 · So why is molecular oxygen $\ce {O2}$ more stable than the molecular ion $\ce {O2^2+}?$ One possible reason that comes to mind is that the antibonding (AB) orbitals, although …

2018年2月16日 · Why are diatomic oxygen molecules STILL reactive especially with metallic elements like sodium and copper even at room temperature? You would think that since the two oxygen atoms …

2024年1月26日 · The boiling point of oxygen is higher than that of nitrogen because of the LD (London dispersion) forces. Oxygen has 12 electrons, and nitrogen has 10, and additionally, lots of oxygen's …
