THINKING T] 2. How many litres of O, will be produced at -6.8C and 108.0 kPa in the decomposition of 203 g of aluminum oxide, A1,0,? (Include a final statement and significant digits) 3. A gas has a volume, V, a pressure, P, and a temperature of T, in Kelvin. If the volume increases by a factor of 1.5, and the temperature triples, by what factor does the new pressure increase or decrease? Show your calculations. 3 4. An unknown metal sulfide reacts with excess hydrochloric acid. X,S+6 HCI =2XCI + 3HS A sample of 20.3g of the metal sulfide produces a gas which is collected over a large body of water. If 12.75 L of gas is collected at 104.0 kPa and 26C, what is the identity of the unknown metal X
