Benzene does not decolourise bromine water, showing it does not undergo electrophilic addition reactions as the delocalised pi structure is very stable. All of the carbon-carbon bond lengths are the same;...
Sodium Chloride has a high melting point, as it has a giant ionic lattice hence has strong electrostatic forces of attraction between oppositely charged ions, which requires lots of energy to overcome the...
PV=nRT n=PV/RT=(1.01*1050.002)/(8.31298)=0.0816 moles
