A10 liter flask at 298 k contains a gaseous mixture of o2 and co2 at 1 atmosphere. which statement is true for the partial pressures of o2 and co2 if 0.2 mole of o2 is present in the flask? (given the universal gas constant r = 0.082 l∙atm/k∙mol)

Which of the following shapes would represent a molecule with two bonded atoms and 3 lone pairs on only one of them , trigonal planar , bent , trigonal pyramidal , linear

Which statement best describes the flow of energy in this scenario

How is energy related to the change of state represented by the model? atoms gain energy as a solid changes to a liquid. atoms gain energy as a solid changes to a gas. atoms lose energy as a solid changes to a liquid. atoms lose energy as a solid changes to a gas.
