The chemical formula for activation powder used to clean black money is C9H7NO3S. It is typically used in a process known as money laundering to remove the black coating on banknotes.
The formula for copper(II) oxide is CuO. This is the commonly met black powder. Copper(I) oxide also exists. This is a red powder, and its formula is Cu2O where the 2 should be a subscript.
I'm sure there is a formula for that, but I was never good with math, The problem is CC is volume and grain is weight. I would take my 5 cc of powder and pour it into an adjustable powder measure, then adjust it until the powder is level with the top. I just did it and it turns out to about 12 grains of black powder.
Impossible to say, but it definitely happened in China not long after they perfected the formula for black powder. The Chinese first used black powder to make various types of fireworks, including firecrackers. But eventually adapted black powder based fireworks technology to warfare by scaling upward.

This formula is NaHCO3.
Black powder absorbs moisture from the atmosphere
Manganese dioxide (MnO2) is a black powder.
Formula: Au
This formula is NaHCO3.
Black powder is much weaker than smokeless powder. Smokeless powder, for this reason, once invented(much after black powder), replaced black powder in guns. However, black powder is still used in fireworks because the extreme explosive power of smokeless powder would prove too dangerous in fireworks.
