Answer:
a) increases.
b) remains the same.
c) decreases. the hydrogen molecules constrict or shrink from actual size!
Explanation:
Since ,
Density is given as mass divided by the volume .
( a ) As the Chlorine gas is compressed , the molecules of gas comes close to each other , and hence , the density increases .
( b ) When the lead is taken to high mountain , its density remains the same , as density is independent of higher pressure , as going to mountain will increase the pressure .
( c ) As the water is freeze , its density decreases ,
Because ice is less dense than water , as seen , the ice ice can float on the surface of water .
The answer is 268.1 u....
The chemical formula for the product is RbBr.
Explanation:
Vander waal forces are defined as the weak electric forces which tend to attract the neutral molecules towards each other in gases, liquefied and solidified gases. And, it is also present in all organic liquids and solids.
Vander wall forces are basically present in all type of molecules. More is the number of carbon atoms present in a molecule more will be the presence of Vander waal forces.
As a result, butanol will have strongest intermolecular force of attraction because it contains more number of carbon atoms and also it has more electronegative oxygen atom.
Whereas n-pentane will have the weakest intermolecular force of attraction between its atoms.
