@Trent57
let us know what you come up with to achieve the 80% goal

Oh wow thanks much - very handy calculators. Now I can experiment a bit.

You are trying to describe something that is grey as either black, or white.
You seem to lack empathy.

But I have a question for about salt dissolving in water. Given that polar molecules only have a partial charge, I don't see how the tiny polar E.N charges on a H2O molecule would be strong enough to pull apart ionic NaCl bonds? Did you have this thought when you were first given this explanation for why salt dissolves in water?

Draw a parallelogram diagram. Apply the cosine rule using the angle φ, which is the complementary angle to θ.

Methane is potentially hazardous; that is why methanethiol is added to it.

Try peracetic acid. It is an organic peroxide.

It does not take much material to produce color.  Perhaps only some of your material degraded.

How do you write down the electrode processes for the element in the table, and what is the brutto process?
3,5 M KCl is the intermediate liquid.

Pt (black) | 0,01 M HCl, 0,09 M KCl, Hr (1 atm) | 3,5 M KCl | 0,01 M HCl, 0,09 M KCl, Quinhydron | Pt (white)

Could be right. The dark color was just odd.

First, read the Forum rules.

Much of the material in inorganic chemistry textbooks deals with this. Also there you will find under what conditions such reactions take place.
Broadly speaking: that's what chemistry is about, so yes, we know. But it is not something that can be explained in a single post. Getting a chemistry degree takes years for a reason, you need to learn many concepts to be able to predict what to expect.

The best course of action is to start with a decent general chemistry book, one that has not only general section, but also a part on inorganic chemistry.

guys thanks for answers  can you guys give me a good book for that
