Normaly the Disulfid will connect two Polymer chain or the same chain for folding each other. Its also called crosslinking.

I dont think so, because the equilibrium will be on left side. Two precipitate on left and on right side only one.
Check the solubility constant from each product.
Also hydrogencarbonate is slightly acidic. Calcium hydroxide strong alcaline, this will neutralise.

First the equation is not balanced, second why do you think this should happen. To get hydrogencarbonate excess of carbondioxide is needed.
This works without and with the calcium already.
Can be find in stalactite caves.

That is what I said above. Why repetation.

Read the principles of Le Chatelier. Here you make from two reactants one product. So it means decrease Volume or increase pressure will give more product .Figure out is the reaction exothermic or endothermic. Means consume or release heat. If it consumes rise temperature, in other case decrease tem...

1. Soap is made of amphipathic particles, the hydrophil part dissolves in water the hydrophob part in fat or oil. The soap molecules develop micelles. A dirt particle is fatty, so the particle will be surounded from the soap molecules, by stickig the hydrophob part in. The hydrophil part will be in ...

Law of mass action

K = C^c*D^d/(A^a*B^b)

K = constant, so changes of one component will affect all others.

No it doesn't effect.

Correct

Because in the logarithmen I used cox/cRed. Not the opposit. Log cox/ cred = - log cred/cox log/cI2/c^2I- = - logc^2I-/ cI2 https://en.m.wikipedia.org/wiki/Nernst_equation You are right it should be a minus like in the Literature but also the reduced form as numerator and the oxidised form as denomi...

Redox Potentials are measured to hydrogen and considered as oxidation.
I-/I2 is positiv. 0,535 V
NO2-/ NO3- is also positiv 0,94 V

Elements are put in by definition as 1 .

The question is what you want to do with this water later on. The sulfuric is an technical one and contain impurities, which can disturb further reactions. Only to lower pH it will work, but 95% is to strong. I dont think you can react pH 5 by using drops, it will go down to 1 or 2. What is the volu...

We have two equations HNO2 + H2O => HNO3 + 2 H+ + 2e- 2 I- => I2 + 2 e- Nernst equation E1 = E0 + 0,059/2*log ( cHNO3 * c^2 H+ /c HNO2) E2 = E0 + 0,059/2 *log (cI2/c^2 I-) First equation cHNO3 = cHNO2 E1 = 0,94 +0,059/2 * log(c^2H+) pH = -log cH+ E1 = 0,94 - 0,059*pH Second equation E2 = 0,535 + 0,0...

Read again the Article, you get both.

You need the complex building constant for CeY-.

Ce 3+ + Y 4- => CeY-

K = CeY-/(Ce 3+ *Y 4-)

pH dependency
