6.(0-2) Black powder was invented in China in the 9th century. It was used as an explosive with propelling properties. Today it is used in fireworks, model rocket engines, and replica black powder weapons. Black powder consists of potassium nitrate (potassium nitrate, KN03), charcoal and sulfur. A variety of chemical reactions take place when this mixture is exploded. One of these is shown below. 2KNO, +S+ 30 → K, S+N, ↑+3C0, 1 Knowing that carbon makes up 15% of the black powder, calculate the total volume of gases (under normal conditions) released when 0.1 kg of black powder explodes. Assume that only the chemical reaction given above occurs.

In the "Méthode Champenoise," grape juice is fermented in a wine bottle to produce sparkling wine. The reaction is C,H12Os (aq) + 2C, H;OH(aq) + 2002(9) Fermentation of 893 ml grape juice (density is 1.0 g/cm') is allowed to take place in a bottle with a total volume of 971 mL until 15% by volume is ethanol (C,H; OH). Assuming that CO2 obeys Henry's law, calculate the partial pressure of CO, in the gas phase and the solubility of CO, in the wine at 25°C. The Henry's law constant for CO, is 3.1 x 10-2 mol/L atm at 25°C with Henry's law in the form C = kP, where C is the concentration of the gas in mol/L. (The density of ethanol is 0.79 g/cm.)
