Question

When a firecracker is lit the gun powder burns rapidly producing gases within the confines ofthe tube which explodes. Gunpowder consists of a mixture of potassium nitrate, carbon, andsulfur (in a 4:7:1 mole ratio). When this mixture is burnt it produces a mixture of carbondioxide, carbon monoxide, nitrogen, potassium carbonate and potassium sulfide. (i)Write a balanced equation for the burning of gunpowder. (ii)If the firecracker had an internal diameter of 0.25 cm and a length of 3 cm, what mass of gun powder (with a density of 1.7 g.cm-³) would the firecracker contain? (iii)Determine the moles of gas that would be produced if this mass of gunpowder wereburnt in the firecracker (iv)Determine the energy released from this gunpowder, assuming that the powder is-prepared stoichiometrically. (hint use the enthalpies of formation provided) (v)If the firecracker was initially at 25.0°C what would you expect the final temperature of inside the firecracker resulting from the combustion of the gunpowder (assuming that-the powder has a heat capacity of 0.953 Jg=¹.K-¹) (vi)What is the maximum pressure inside the firecracker assuming that the gases produce dare heated in the firecracker without a change in volume?
