- Volume changes when mixing DMSO and water - Chemistry Stack Exchange
Since I know that a mixture of 500ml $\ce {H_2O}$ and 500ml ethanol gives less than a liter of mixture I wonder how strong this effect is when mixing DMSO and $\ce {H_2O}$
- Whats the difference between 2O and O2 [duplicate]
$\ce {2O}$ is basically two atoms of oxygen, unbonded and separate On the other hand, $\ce {O2}$ is oxygen molecule, which is more commonly called oxygen gas
- How does a dry shampoo work? - Chemistry Stack Exchange
1 From my chemistry knowledge, I know that soaps are made from fatty acids and some sort of base and this reaction also gives us $\ce {H_2O}$ so the grease in hair dissolves and gets washed away in water What I don't understand is how dry shampoos can have a cleaning effect on dirt or grease and how they work
- inorganic chemistry - Balanced Chemical Equations of the preparation of . . .
Now when we were doing the experiment to prepare sodium peroxoborate we added, the $\ce {NaOH}$ first and then $\ce {H_2O_2}$ How do I write the chemical equations for the borax with just the sodium hydroxide and then that product with the hydrogen peroxide
- Enthalpy of reaction between ammonia and oxygen
For a reaction system, $$\ce {4NH_3 (g) + 5O_2 (g) -> 6H_2O (g) + 4NO (g)}$$ In the case of the example you've provided, you are assuming this reaction is taking place at standard conditions If we assume for a stiociometic amount of reactants, then the extend of reaction, $\xi$, should be equal to 1 Therefore,

2 Is $\ce {K_2Cr_2O_7}$ diamagnetic or paramagnetic? While näive theory predicts it's diamagnetic, but we can't be sure I cannot find any literature on this topic Nor does Wiki has that information Even Chem spider doesn't I don't know about any other reliable sources
- Why is dimethyloxonium cation stronger acid than hydronium?
A powerful but often overlooked factor in determining a substance's acidity and basicity is the effect of the solvent (or lack thereof) in which it is dissolved You are not wrong; in the gas phase, $\ce {H_3O^ {+}}$ is indeed a stronger acid than $\ce { (CH_3)_2OH^ {+}}$, by a factor of about $5\times 10^ {18}$ This can be seen by comparing the proton affinities of the conjugated bases
- Calculate the valence of Fe2O3 - Chemistry Stack Exchange
And then, you can calculate the valence of $\ce {FeO}$ and $\ce {Fe_2O_3}$ But how? I made a question before Calculating valence of oxides, but it was wrongly formulated (they corrected me on the definition of Valence, but turns out what I actually need was how to calculate it), so I'm flagging it to be closed
