Dalton\'s Law of Partial Pressures For a blend of gasses in a holder, P Total = P 1 + P 2 + P 3 + . . .

Slide 2

Collecting gas over H 2 O

Slide 3

Dalton\'s Law of Partial Pressures For gasses gathered over water: P gas = P atm – P H2O

Slide 4

what number grams of magnesium are required to yield 1.12 liters of H 2 gathered by removal of water at 26 o C and 748 torr? (Vapor weight: 3.4 kPa or 25.5 torr) Mg (s) + 2 HCl (aq)  MgCl 2(aq) + H 2(g)

Slide 5

Partial Pressures Mole Fraction (X gas ) = mols of gas/aggregate mols of gasses in blend X gas = n gas/n add up to

Slide 6

Calculate the aggregate weight (in atm ) of a blend that contains 1.00 gram of H 2 and 1.00 gram of He in a 5.00-liter compartment at 21 o C. What are the halfway weights of the H 2 and He?

Slide 7

Two jars are associated with a stopcock. The main cup has a volume of 5 liters and contains nitrogen gas at a weight of 0.75 atm. The second flagon has a volume of 8 L and contains oxygen gas at a weight of 1.25 atm. At the point when the stopcock between the carafes is opened and the gasses are allowed to blend, what will the weight be in the subsequent blend?

Slide 8

Practice Problems what number grams of antimony(III) chloride can be created from 3570 cm 3 of chlorine at STP responding with an overabundance of antimony? 2 Sb (s) + 3 Cl 2(g)  2 SbCl 3(s Ans. 24.437 g SbCl 3 What volume of oxygen can be gathered by relocation of water at 745 torr and 23 o C by the total disintegration of 5.00 g of KClO 3 ? (H 2 O = 2.8 kPa or 21 torr ) 2 KClO 3(s) + warm  2 KCl (s) + 3 O 2(g) Ans. 1.553 liters What\'s the halfway weight of carbon dioxide in a holder that holds 5 moles of carbon dioxide, 3 moles of nitrogen, and 1 mole of hydrogen and has an aggregate weight of 1.05 atm ? Ans. 0.583 atm
