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.
Each hydrogen peroxide molecule contains #2xxO-H# bonds. As in water, the #O-H# bonds are polar, i.e there is substantial charge separation. Of course, the #O-O# bond itself is non-polar so that when we assign oxidation states to this molecule, we have #H^(+I)# and #O^(-I)#. Nevertheless, we would rightly predict that hydrogen peroxide is polar.
