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 …

This website has a live "$\ce {O2}$ solubility in water" calculator based on empirical data. The authors use two different equations for two different temperature regimes: $\ce {0 ^oC - 30 …

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. …

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 …

If you were to super-heat a mole of carbon dioxide gas, at what point would it decompose into carbon and oxygen? If it decomposes into carbon monoxide and oxygen, at what point do …

Jul 31, 2019 · This means that the order of reaction for oxygen gas $\ce {O2}$ is $ (-1)$ that the doubling of the concentration of $\ce {O2}$ leads to a reduction in the rate of the reaction by half.

Oct 2, 2017 · I want to investigate how temperature affect the concentration of oxygen in air as it will affect how much oxygen we inhale per breathe. Oxygen by percent composition in air is …

Feb 28, 2016 · TL;DR: The $\ce {O-O}$ and $\ce {S-S}$ bonds, such as those in $\ce {O2^2-}$ and $\ce {S2^2-}$, are derived from $\sigma$-type overlap. However, because the $\pi$ and …

Aug 8, 2012 · $\ce {CO2}$ into $\ce {CO + O2}$ is easier, but you need a catalyst and about $\pu {1500 °C}$ as reported by Richard Van Noorden’ article “ Recycling carbon dioxide into petrol …

I have encountered this equation: $$\\ce{SO4^2- -> S2O8^2-}$$ In this reaction 2 of the oxygen ions change from $-2$ to $-1$ so they are getting oxidized. It is because two oxygen ions are …
