Hello, the question is already in the title. I'm also interested in whether these paints are water-resistant or even impermeable, and how UV-resistant they are.
Hello! I wanted to ask if anyone knows what you can etch away with formic acid. Can formic acid etch bone or even metal? I know that formic acid can burn skin, but not etch it away.
I need some very good chemistry books, preferably with AFG and solutions. Can anyone recommend any? And maybe give me some tips to help me understand this?
What do you have to do for this task? Task 6 is what I'm referring to. I need it for work tomorrow!
Hey people, We recently got an assignment back and have to work on the first three problems (a kind of correction). One of them is about the fact that there are four bottles, but we don't know where hydrochloric acid, sodium hydroxide, distilled water, and saline solution are. I knew the first four, but I…
Are they there to transport electrons? Or not?

Because of the dipole character by amino (NH2) and carboxyl group (COOH), hydrogen bridge bonds can form. Glycine is thus soluble in water. Alkanes are non-polar, accordingly glycine does not dissolve in heptane.
The ethanol, a short-chain alcohol or Alkanol, I doubt it does not dissolve in glycine. In ethanol, the hydroxyl group (OH) has the greater influence, which is why ethanol also dissolves in water.
If a substance such as e.g. Glycine dissolves in polar solvents such as water, it will also dissolve in other polar solvents such as (short-chain) alcohols.
If I have a faulty gap in my statement, please indicate.
Glycine is not readily soluble in ethanol, but nevertheless somewhat soluble. However, I have not found any specific data.
Glycine has a basic amino group and an acid carboxyl group. It is therefore predominantly present as zwitterion +H3N-CH2-COO–. This could explain the poor solubility in ethanol, in contrast to similar propanoic acid.
In nonpolar substances such as heptane, both polar and ionic substances are poorly soluble.
