Hello, our chemistry assignment is about how salt was mined in the past and how it is mined today. I've been researching for some time, but haven't found anything suitable. The explanation should be about a page long.
I would be very grateful if you could help me.

Loading...Hello, Can someone please check whether I have solved the task correctly? Reaction equation: 4K + O2 —> 2K2O Mass K2O: 82.425 g And one more question: potassium hexacyanoferrate(II) is a potassium salt that is insoluble, is that right?
It's important that the exhaust gases come into contact with the catalyst. Therefore, efforts are made to create a large surface area in a small space. The solution is a honeycomb-shaped, porous structure. Here's a model example (image). They each have an edge length of 5 cm (see the picture on the right). The cube…
Recently, at the end of summer vacation, at 7 or 8 p.m., I saw a thunderstorm on a football field near Weiz. All the clouds were illuminated by the sunset, and it was a bit humid. Then, suddenly, a red flash flashed above a cloud! Is that possible? Did I imagine it? Are such phenomena…
Can someone please explain this to me? I don't know how to proceed.
Hey, I once saw a trick somewhere where you can mix hydrogen peroxide and one (or two) other substances to make metals rust extremely quickly (within a few minutes of exposure) without the solution being harmful or dangerous to humans. In other words, it does not contain any acids or the like. Maybe the chemists…
In the past, seawater was let dry or brine water was boiled from mineral sources. Salt mines were rather the exceptions.
You can find it in many local names – Hallstadt, Salzgitter, Reichenhall…
Today, salt is cheapest mass goods. Stone salt is a by-product in 600 m deep potassium mines. Germany is rich here as we live in an old, evaporated sea basin, the Zechsteinmeer.
Mallet here tried?
Stone salt was mined earlier under days, nowadays it is dissolved as much as I know with water because it is easier
