Chemical formula of gunpowder?
Gunpowder is a finely ground mixture of Potassium Nitrate (75%), Sulphur (10%) and Charcoal (15% w/w). The mixture burns extremely quickly, evolving gases which increase the reaction volume and thus make it a powerful propellant.

The softball hits the ground first because it is less affected by air resistance.
Why do you think potassium nitrate charcoal and sulfur become explosive after they are ground together?
Potassium nitrate, charcoal, and sulfur form an explosive mixture known as black powder when ground together. The combination creates a highly reactive mixture due to the presence of oxidizing agents (potassium nitrate) and fuel (charcoal and sulfur), which allows for the rapid release of energy upon ignition. The finely ground particles increase the surface area, promoting faster combustion and leading to the explosive behavior when ignited.
If oxygen is exposed to a glowing ember will it explode?
It should not explode. With what would the oxygen combust? About 20% of the air is oxygen. Oxygen does not readily combine with itself. However, if you put a spark into a cup of liquid hydrogen, I bet it would react rather violently. And there is a YouTube video of a fellow igniting charcoal with liquid oxygen. The oxygen does not explode, but the fire burns the charcoal really well. And the barbecue. And eventually the ground below the grill.
