Sketch a microscopic picture of water and distinguish between intramolecular bonds and intermolecular forces. Which correspond to the bonds we draw in Lewis structures?
Chapter 5 Pressure: The United States National Institute of Standards and Technology uses one atmosphere as the standard pressure. Pressure is force per unit area. The S. I. unit of force is the newton. Force = mass x acceleration 1 newton = 1 kg m s-2 The S. I. unit of pressure is the pascal. 1 pascal (Pa) = 1 newton / meter2 1 pascal = 1 kg m s-2m-2 = 1 kg s-2m-1 1 bar = 1 x 105 pascals (Pa) 1 bar = 100 kilopascals (kPa) 1 bar = 1 x 105 kg s-2m-1 1 bar = 0.9872 atmospheres 1 atmosphere = 760 mm Hg = 760 torr 1 atmosphere = 14.6960 pounds per square inch 1 atmosphere = 1.01325 bar 1 atmosphere = 1.01325 x 10^5pascals Memorize the following conversion factor: 1 atmosphere = 760 mm Hg = 760 torr General Gas Law: P1V1/(T1) = P2V2/(T2) This equation ca
