Question

consider figure 13.1 below. What are questions 8&9? volume be at STP? s consider Figure 13.1. the height of the mercury column in the leveling bulb is 10 mm greater than that in the gas buret and atmospheric pressure is 670 mm, what is the pressure on the gas trapped in the buret? Consider Figure 13.1. If the level of the mercury in the leveling bulb is lowered, what happens to the volume of the gas in the gas buret? 40. show law, Charles's law, and Avogadro's law can be derived from the ideal gas law that Boyle's p nRT P Constant AN v constant Curr Cons Methane burns in oxygen to produce CO2 and H2O T T CH4 (g)+ 202 (g) 2H20() t CO2 (g) If 0.50 L of gaseous CH4 is burned at STP, what volume of O2 is required for complete combustion What volume of CO, is produced?

Explanation / Answer

(8)

Pgas = Patm + Phf

Phf denotes the pressure due to height difference.

Phf = d*g*h = 13593*9.81*0.01 = 1333.473 Pa = 10 mm Hg

So,

Pgas = 670 + 10 = 680 mm Hg

(9)

Volume occupied by the gas in the buret decreases.

(11)

From the reaction stoichiometry,

Volume of oxygen needed = 2*Volume of methane = 2*0.5 = 1 L

Volume of CO2 produced = Volume of methane = 0.5 L
