A sample of 18 g of oxygen gas (O2) is confined in a container at 200 kPa and 273 K. The gas is allowed to expand adiabatically and reversibly to 100 kPa. Calculate the final temperature of the gas. The molar heat capacity at constant pressure (CP,m) of O2 is 29.355 J mol-1 K-1
& b 8. 32 g of oxygen gas (O2) at room temperature a) contains 0.5 mole of O molecules b) 4 moles of O atoms c) could make two moles of CO, molecules d) a &b e) none of the above me number of carbon atom:
1. One mole of oxygen gas (O2) molecules has fewer atoms than one mole of ozone gas (O3) molecules ( True or false) 2. One molecule of oxygen gas (O2) has fewer atoms than one mole of ozone gas (O3) (True or false)
Ozone decomposes to form oxygen molecules and oxygen atoms, O3(g) ? O2(g) + O(g), in the upper atmosphere. The energy of activation for this reaction is 93.1 kJ/mol. At 600 K, the rate constant for this reaction is 3.37
A sample containing 8.00 g of O2 gas has a volume of 35.0 L at constant pressure and temperature. (Help Please ASAP) i. A sample containing 8.00 g of O2 gas has a volume of 35.0 L at constant pressure and temperature. What is the new volume, in liters, after 0.550 mole of O2 gas is added to the initial sample 8.00 g of O2? ii. A sample containing 8.00 g of O2 gas has a volume of 35.0 L...
A sample of oxygen (O2) gas is at a temperature of 340K and occupies a volume of 1.2cm3. What temperature will the sample of gas be at if the volume is decreased to 200cm3?
11. Consider a sample of hydrogen (H) and another sample of oxygen (O2). Both gases are at the same temperature and pressure. The volume of each gas is equal. (5) a) which gas has the greatest number of moles, or are they the same? b) which gas has the greatest number of molecules, or are they the same? c) which gas has the greatest mass, or are they the same? d) Which gas has the highest kinetic energy, or are...
A sample containing 5.60 g O2 gas has a volume of 33.0 L . Pressure and temperature remain constant. What is the new volume if 0.550 mole O2 gas is added? Oxygen is released until the volume is 10.0 L . How many moles of O2 are removed? What is the volume after 3.00 g He is added to the O2 gas already in the container?
}We mix 0.25 g of oxygen gas (O2) and 1.5 g nitrogen gas (N2) in a 2 L container at 20oC. Assuming both gases behave ideally, (a)what is the partial pressure of oxygen? (b)what is the partial pressure of nitrogen? (c)what is the total pressure in the container? Molar masses are 32 g/mol for oxygen and 28 g/mol for nitrogen.
When 9.0 g of hydrogen gas, H2, reacts with oxygen gas, O2, 73.0 g of water is produced. a) What is the theoretical yield of water? b) What is the percentage yield?
