Causes of Retinal Hemorrhage. In adults, the causes of retinal hemorrhages are quite common and easy to understand. A forceful blow to the head can result in a retinal hemorrhage. Those who have been in an accident, been assaulted or have taken a fall in which they hit their head may experience a retinal hemorrhage.
Carbon monoxide is polar because oxygen is more electronegative than carbon giving oxygen a partila negative charge and carbon a partial positive charge. There is a net dipole moment.n the free carbon monoxide, a net negative charge Î´- remains at the carbon end and the molecule has a small dipole moment of 0.122 D The molecule is therefore asymmetric: oxygen has more electron density than carbon, and is also slightly positively charged compared to carbon being negative.
Polarity is determined by the dipole-dipole moment about a molecule. If a molecule has ligands (atoms bonded to it) that are different in their electronegativity, such as CH3C â¦ l, it will be very polar. molecule like CH4, (methane), will be nonpolar. All the ligands attached to carbon have the same electronegativity, so there is no difference in dipole around carbon.
