2017年1月9日 · The common confusion here is that two very different things have the same name. O is a free oxygen atom and 2 O X 2 is two oxygen atoms chemically bound to form an oxygen molecule. …

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!

2018年11月25日 · But why do we call O2 oxygen is my question? I thought only an atom with 8 protons can be called oxygen?

2014年7月18日 · S-p mixing is the primary cause of the difference in the molecular orbitals of nitrogen and oxygen, which is influenced by the initial atomic orbital energies. The lighter second period …

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?

The reaction between hydrogen and oxygen to yield water vapor has ΔH∘ = − 484kJ Δ H ∘ = 484 k J. How much pV p V work is done, and what is the value of ΔE Δ E in kilojoules for the reaction of 0.50 mol …

2025年4月13日 · The enthalpy of formation of O2 is zero at any particular temperature. The element is already in its ''standard state'' . Also please note that as per IUPAC, there is no standard temperature, it …

The standard reduction potential of diatomic oxygen in acidic conditions is +1.23 volts. However, the standard reduction potential of diatomic oxygen in basic conditions is only +0.40 volts. Why i...

2014年8月9日 · I have noticed that liquid OX2 O X 2 (I clarify it as OX2 O X 2 because oxygen exists in several other forms which have different colors in the liquid state than OX2 O X 2) has a light blue …

2024年4月17日 · There is a good reason for not being able to find the mid-IR absorption spectra of nitrogen and oxygen. Their vibrations are infrared inactive. Infrared absorption peaks are observed …
