Which of the following is true about cos.1.cos has no dipole moment because the molecule is linear and dipole moments cancel in linear molecules.2.cos has a dipole moment because it is asymmetric and the dipole moments do not completely cancel.3.cos has a dipole moment because the molecule is bent and the dipole moments combine.4.cos has no dipole moment because it is bent and the dipole moments cancel5.cos has no dipole moment because its bonds are all non polar.

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.
