Chemistry

Small rocket engines, such as model rockets, contain KClO33 toprovide oxygen for the combustion reaction fueling the rocketmotor. The relevant reaction for KClO33 is: 2 KClO33(s) → 2 KCl(s)+ 3 O22(g)

If 117.0 grams of solid KClO33 are burned in one of these rocketmotors, how many liters of gaseous O22 are produced at 1.18 atm ofpressure and 550.0 ºC?

Gaseous sulfur dioxide, a component of acid rain, is made as aproduct of the combustion of sulfur-containing fuels. Calculate thevolume of sulfur dioxide produced at 22.4 °C and 0.925 atm by thecombustion of 8902 g of fuel that contains 5.55% of sulfur by mass.S88 (s) + 8 O22(g)→ 8 SO22(g)
