Water Vapor Confirmed As Major Player In Climate Change - ScienceDaily (Nov. 18, 2008) — Water vapor is known to be Earth's most abundant greenhouse gas, but the extent of its contribution to global warming has been debated. Using recent NASA satellite data, researchers have estimated more precisely than ever the heat-trapping effect of water in the air, validating the role of the gas as a critical component of climate change. See also: Earth & Climate Environmental Issues Global Warming Water Climate Pollution Atmosphere Reference Consensus of scientists regarding global warming Carbon cycle Atmospheric chemistry Greenhouse effect Andrew Dessler and colleagues from Texas A&M University in College Station confirmed that the heat-amplifying effect of water vapor is potent enough to double the climate warming caused by increased levels of carbon dioxide in the atmosphere. With new observations, the scientists confirmed experimentally what existing climate models had anticipated theoretically. The research team used novel data from the Atmosph....

Question : This is for a general chem college class. How many kJ would of heat would be liberated by the condensation of 5.00 g of acetone? (sorry it got cut off) I tried 2.61 many times..its online homework and the system keeps saying that it is wrong..idk y..cause i calculated the same answer.
Answer : 5.00 g acetone = 0.0861 mole (5.0g/58.08g/mol=0.0861 mol) 0.0861 mol x 30.3 kJ/mol = 2.61 kJ
Answer : 5.00 g acetone = 0.0861 mole (5.0g/58.08g/mol=0.0861 mol) 0.0861 mol x 30.3 kJ/mol = 2.61 kJ
Question : a compound is heated to produce a gas whose molecular weight is to be determined. the gas is collected by displacing water in a water-filled flask inverted in a trough of water. why is vapor pressure necessary to calculate the molecular weight of gas, but doesn't need to be measured during the experiment?
Answer : The vapor pressure of water is measured when you measure the pressure of the gas collected. The pressure measured is the pressure of the gas that is the product of the reaction plus the vapor pressure. By subtracting the vapor pressure from the measured pressure you get the pressure of the gas whose molecular weight you are trying to determine.
