Yes, they are. Mixing powders together produces a mixture but it doesn't induce any chemical change.
No they are not because they have different particles resulting in a big mixup messing everything up
NONONO
At the room temperature they remain elements in a mixure; by heating a compound is obtained, carbon disulfide.
No, the sulfur and iron still have their individual properties. Iron is still magnetic and the sulfur can be dissolved by carbon disulfide leaving behind the iron.
total no of elements in periodic table is 112.Some of which are still unnamed. Elements on the periodic table is classifies into metals, non-metals, semiconductors, and elements that are radioactive. Elements are arranged in increasing order of their atomic number. In a periodic table on the left are the metals, on the right are all non-metals and in the middle are the transition metals.
Enjoy life? There would be no life without certain elements. Carbon, oxygen, nitrogen, phosphorous and calcium, to name a few.
Co2 CH4 tetrachlorofluro carbon CFCs (sulfur hexafluoride, HFCs, and PFCs) nitrous oxide Water Vapor is still the primary greenhouse gas making up over 75% of the greenhouse effect.
Yes if they are simply mixed they are still elements.

Yes we can

Black powder is a mixture, not an element. It consists of potassium nitrate, charcoal and sulfur in the ratio 75:15:10. It is used in fireworks and was once used to propel bullets in guns(still used with some antique guns).

yet its not possible to separate elements of carbon dioxide dry ice.. and I am still searching on it...so when i got answer of this question i will share it on my blog name newsboxblog.blogspot dot com.thanks
Physical change- it is still sulfur
Origin: It's a product of heat and pressure of lesser elements. It is the end of a radioactive decomposition of higher elements. So, it exists whenever these processes are occurring. Generally, produced in stars. Carbon exists in all living things, and is basis for all living organisms. Even, after living things die, they still posses their carbon. (Hence, why we can apply carbon dating to most things.)
The gold powder is also a solid.
