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.
(2) S-Br bond is the most polar. GROUP D: Si-Cl bond is the most polar. GROUP -E : because of the presence of hydrogen,the P-block elements take up a negative charge and act as an anion. thus according to the rule , Sn-H bond is the most polar. GROUP - F : here the P-Block elements act as a cation. So smaller the size ,grater the polarity.as aluminium is the smallest among the given, Al-Br bond is the most polar. Please refer to the periodic table for any doubts in the position of the elements. muruganandam p Â· 10 years ago
