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.
Carbon dioxide is a non-polar molecule because carbon and oxygen have similar electronegativities (Carbon is 2.55 and Oxygen is 3.44). Because of this, there is no movement of â¦ electron density (or dipole moment) in one direction or the other to create polarity. molecule of carbon monoxide contains 1 atom of carbon and 1 atom of oxygen, so the formula is CO (not to be confused with Co). A molecule of carbon dioxide contains 1 atom â¦ of carbon and 2 atoms of formula, so the formula is CO2.
