Is black powder a compound?
Yes
Is black powder a element or compound?
it is indeed a compound, but its more of a mixture actually.
Is potassium nitrate the compound in black powder?
Potassium nitrate (KNO3) is the chemical name for the compound also known as saltpeter, which is one of the major ingredients of black powder (the other major ingredients being carbon, generally charcoal, and sulphur).
If a light green powder is heated in a test tube A gas is given off while the solid becomes black In which classification of matter does the green powder belong?
The green powder is copper (2) carbonate. When heated it decomposes to give copper (2) oxide (which is black) and carbon dioxide . It is a compound.
What is crystal powder?
A powder of a compound having a crystalline structure.
Is coco powder a compound?
No, it is a mixture.
What compound is a light green powder?
I think it could be Barium sulphate if its a powder
How can you find out if powder is a compound?
Only after a serious analysis (chemical and physical) of the powder.
What is a disadvantage of black powder?
Black powder absorbs moisture from the atmosphere
What is the difference between smokeless powder and black powder?
Black powder is a mixture made by finely integrating potassium nitrate, charcoal and sulfur in the ratio 75:15:10 into each other. Smokeless powder consists primarily of nitrocellulose(also called guncotton) which is a compound made by reacting cellulose(cotton is a pure source, hence the name) with nitric acid with sulfuric acid used as a catalyst. Nitroglycerine, nitroangudine and other additives are also added. Smokeless powder is much stronger than black powder. Smokeless powder is used in guns, to propel bullets. Black powder is used to propel fireworks and was once used in guns(when smokeless powders were not invented).
Is sulfur powder a compound?
No. Sulphur is an element.
How does black powder compare to smokeless powder in power?
Black powder and smokeless powder differ significantly in power. Smokeless powder is more powerful, providing higher velocities and energy compared to black powder. Smokeless powder's cleaner burn and increased efficiency make it the standard propellant for modern firearms, offering better performance and reduced fouling.
