What is the chemical formula of gunpowder? A simple, commonly cited, chemical equation for the combustion of gunpowder is: 2 KNO3 + S + 3 C → K2S + N2 + 3 CO2. A balanced, but still simplified, equation is: 10 KNO3 + 3 S + 8 C → 2 K2CO3 + 3 K2SO4 + 6 CO2 + 5 N2.
What chemicals make up gunpowder? Black powder consists of a fuel (charcoal), an oxidizer (saltpeter or niter), and a stabilizer (sulfur) to allow for a constant reaction. The reaction would be slow, like a wood fire, if not for the oxidizing agent. Carbon in a fire must draw oxygen from the air, but the saltpeter in gunpowder provides the oxygen.
What makes gunpowder explosive? Gunpowder is a powder mixture of very combustible (burnable) chemicals, namely sulfur, charcoal, and potassium nitrate. … All this energy forces the gunpowder outward, further igniting more of it and causing the explosion that we can see. Answer 3: What makes gunpowder seem to “explode” is because it burns very rapidly.
What is the chemical structure of a black powder? It consists of charcoal (carbon), saltpeter (potassium nitrate or sometimes sodium nitrate), and sulfur. Charcoal and sulfur act as the fuel for the explosion, while saltpeter acts as an oxidizer. Sulfur also lowers the ignition temperature, which increases the combustion rate.

Why do formula feeding newborns hiccups after?
Hiccups are especially common in newborns and infants. “We don’t know exactly why, but hiccups may be caused by increased gas in the stomach,” Dr. Liermann says. “If babies overfeed or gulp air during eating, that could cause the stomach to expand and rub against the diaphragm, generating those hiccups.”
