Amixture of ar, he, and o2 has a total pressure of 1,015 kpa, and partial pressures of argon and helium of 152 kpa and 305 kpa, respectively. what is the partial pressure of oxygen in this mixture?

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.
