True, if this is a true or false question.
HF - The liquid state of this compound will exhibit hydrogen bonding due to the large electronegativity of H and F.
CF4 - The liquid state of this compound will exhibit van der Waals forces.
H2S - The liquid state of this compound will exhibit dipole-dipole or electrostatic attraction forces.
A displacement reaction will occur from the system given above. The chlorine molecules will displace the bromide ions in the solution of sodium bromide. The reaction will yield to sodium chloride and bromine. The reaction will be:
2NaBr + Cl2 = 2NaCl + Br2
Draw CO2, C in the middle and O on each side. O has 6 e- and C has 4, so 6+6+4= 14 e-.
