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.
The above answer is incorrect. The correct answer is that AlCl3 is non polar, even though it is trigonal planar the atoms are spread symetrically making it non-polar!hey may be classified as polar and non-polar. A non-polar compound occurs when there is an equal sharing of electrons between two different atoms. Examples of household non-polar compounds include fats, oil and petrol/gasoline.
