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!

And finally there is $\ce {O#O}$ where both oxygens are positively charged and are free radicals. Why are both positively charged? It is because 3 bonds already to oxygen means 1 lone pair …

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 …

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 …

2017年4月29日 · Methane $\\ce{CH4}$ is symmetrical and non polar, and so is oxygen $\\ce{O2}$. But $\\ce{O2}$ doesn't absorb IR. Why is that? People say that if a molecule can …

In Earth's atmosphere, the NO formed by lightning, reacts with O2 to form NO2, which then forms HNO3. So in our environment, no NO does not return to N2 and O2, because it reacts with …

2018年2月16日 · -2 Oxygen (O2) generally exists as diradicals i.e. each oxygen bonded to each other through single bonds and the remaining two electrons remains on each oxygen atoms as …

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 …

2015年7月9日 · Although CO has a much greater affinity for a ferrous heme than does O2 (by a factor of about 25,000), the affinity of CO for deoxyhemoglobin is only about 200 times greater …
