C2O4(2-) + MnO4(-) => CO2 + Mn(2+)

5(C2O4(2-) => 2 CO2 + 2e-)

2(8 H(+) + MnO4(-) + 5e- => Mn(2+) + 4 H2O)

Yep, looks like you nailed it.

Could the site be wrong? There really isn't too much else that could be happening in this case

This is an acid base reaction. Since HF is a stronger acid than HCO3(-), it will give it a proton. You're on the right track. NaHCO3 + HF => H2CO3 + NaF After the carbonic acid forms, it will quickly decompose to water and carbon dioxide. (As instanced by the bubbling from solution). H2CO3 => CO2 + ...

Conversion problem. To get grams per millimole, all you would have to do is divide by 1,000. IE : move the decimal left three spaces.

In this case, there are 0.2032814 grams / mmol

There is no direct way to calculate the power of a reaction, only its energy. This will be tabulated from a reference according to Hess' Law. This is probably quite a bit ahead of stoichiometry, however. Here is an example : 0.90 grams of Aluminum and 2.10 grams of potassium perchlorate are mixed ca...

The dangerous part of mixing bleach and ammonia is formation of chloramines. NH2Cl, NHCl2 and NCl3 are all poisons. None of the products of the 'final' equation are dangerous at all : 4NH3 + 3NaOCl --> 2NaOH + NaCl + H2O + 2NH4Cl + N2 I'm not familiar with NaONH3; it must be some sort of intermediat...

Ah! Well you can figure this out using the molar mass. The molar mass of something is the sum of the atomic weights of its parts. Use your periodic table to guide you. In your example, you would look up Ca to find that it has a molar mass of 40.1 grams per mole. Cl is 35.5 grams per mole, but it com...

I have been digging up a few patents that are relevant, but I doubt there is anything you haven't seen there.

Do you have the means to use ultrasound to disperse the nanoparticles?

Acetic acid heated with urea, according to A. Vogel's Textbook of Practical Organic Chemistry, will produce acetamide and carbamic acid. Carbamic acid, which is quite unstable, decomposes quickly to ammonia and carbon dioxide. (NH2)2CO + CH3COOH => CH3CONH2 + CO2 + NH3 Good luck! PS:...

4 NaHSO4 + 5 LiClO => 2 Cl2 + LiClO3 + 2 Na2SO4 + 2 H2O + 2 Li2SO4 Something like that. The exact reaction depends on the temperature, amount of bisulfate added and concentration of the reactants. Sometimes, chlorine oxides will bubble out of the solution. The only thing that is for sure is the for...

What kind of solutions are you making?

What is the nature of the nanoparticles that you wish to create?

Note : This means 55 ml of sulfuric acid for 1 liter of water. Another note : the sulfuric acid, after this dilution, is going to be approximately 9% concentrated. Final note : The error of this calculation is likely on the side of caution, this amount of water assumes complete dissociation of 98% s...

Conversion problem. Convert to mL, multiply by density, divide by molar mass and multiply the Avagadro's number. 1.25 oz * 29.6 mL / oz = 37.0 mL 37.0 mL * 0.798 g / mL = 29.526 g Molar mass = 46.06844 g / mol 29.526 g / 46.06844 g / mol = 0.6409 moles Avagadro's number = 6.02 * 10^23 0.6409 moles *...

H2SO4 => HSO4(-) + H(+) From the CRC Handbook of Chemistry and Physics, the dH of this reaction is, according to Hess' Law, -95.34 kJ / mol. Since we can assume any value of moles as long as we keep it consistent, let's do one mole of sulfuric acid and convert this to milliliters later. -95,340 J is...
