1) show that boyle's law, charles's law, and avogado's law canbe derived from the ideal-gas law. 2) methane burns in oxygen to produce CO2 and H20 CH4(g)+ 202(g)-------- 2H20(l) + CO2(g) if 2.5 L of gaseous CH4 is burned at STP,what volume of 02 is required for complete combustion?what volume of CO2 is produced? 1) show that boyle's law, charles's law, and avogado's law canbe derived from the ideal-gas law. 2) methane burns in oxygen to produce CO2 and H20 CH4(g)+ 202(g)-------- 2H20(l) + CO2(g) if 2.5 L of gaseous CH4 is burned at STP,what volume of 02 is required for complete combustion?what volume of CO2 is produced? if 2.5 L of gaseous CH4 is burned at STP,what volume of 02 is required for complete combustion?what volume of CO2 is produced?Explanation / Answer
Boyle's Law describes a closed system (which means n isconstant) where temperature is constant. Therefore, PV = constant. You may have seen this writtenas PV = k, where k is the constant. You can then set anyclosed pressure-volume system at the same temperature, equal toeach other, shown as P1V1 =P2V2.
Charles's Law follows the same pattern as Boyle's Law, butwith pressure constant instead of temperature.
Avogadro's Law starts with a rearrangement of the ideal gaslaw: PV/nT = R R is a constant, so you can set 2 different systems equal toeach other, just like we did for Boyle's Law: P1V1 /n1T1 = P2V2 /n2T2
2. This is a stoichiometry problem, but you have to look upthe density values. Density of CH4= 0.113 mol/L Density of O2= 22.4 L/mol
(2.5 L CH4) (0.113 mol/L) (2 molO2 / 1 mol CH4) (22.4 L / 1 molO2) = volume of O2
