Yes!!! The allotrope ' yellow flowers of sulphur' is quite soft and can be scratched with a finger nail.
Yes
it will rust in few hours
All zinc nails rust over a long period of time. One that has been scratched will rust sooner. You could touch over with a zinc paint. I would need to know more. I cant see any problems.
First soak it in water for 15-20 min. Then try to scratch it off with your thumb. If u don't have nails use a sharp object to scratch it off. Actually just use nail polish remover
It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5
It can be scratched by a diamond, corundum, topaz, and quartz.

The Mohs Scale of Hardness is used to measure hardness of a mineral, which is its resistance to scratching. It is a quantitative scale, which relies on the relative hardness of other minerals . Higher numbered minerals scratch lower numbered ones. You can use every day objects like a glass plate, a knife, or a nail to distinguish hard and soft. Hard minerals scratch glass, but can't be scratched with a knife blade of a nail. Soft minerals will not scratch glass, but can be scratched with a knife blade or masonry nail. You can purchase hardness kits to help make these distinctions.
The hardness of glass is around 6, and the hardness of iron is about 5. So your mineral is probably around a 5.5.
No. Only another diamond can scratch a diamond.
Mineral hardness is tested on a glass plate or usually a finger nail.
The answer is quite complicated in fact I don't know the exact answer. What I really know is that a geologist will probably know the exact answer. Geologists study rocks and rocks have lots of minerals. You can search the answer as well by looking at geologist websites. If it doesn't work then I hope someone else can edit this answer.
There are two ways. One way is to buy a scratch test kit and follow the instructions. They will tell you to try to scratch minerals of certain hardnesses and find the hardest one it can scratch. For example, if it scratches a mineral with a hardness of 6 but not one with a hardness of 7, the hardness would be between 6 and 7. If you do not have one of those available, you can try scratching common objects. Your fingernail is 1.5, a penny is 2.5, a pocketknife blade is 5.0, window glass is 5.5, a steel file is 6.5, and quartz is 7.0.
Yes magnatite does and it can be scratched by a nail Jk!
