Answer:
Explanation:
a ) false.
NH₃ is more polar molecule than PH₃ so inter-molucular attraction is greater in NH₃ ( hydrogen bond ) . Hence vapour pressure is low for NH₃ .
b ) false .
The average kinetic energy of boiling water molecules is lower on a mountaintop than it is at sea level. It is so because water boils at lower temperture on mountain and kinetic energy of molecules depends upon temperature .
c ) false
vapour pressure depends upon temperature .
d ) True
CCl4 is more volatile than CBr4
e ) false
vapour pressure increases as temperature increases.
Voltaic cells convert chemical energy to electrical energy by means of an oxidation-reduction reaction while Electrolytic cells convert electrical energy to chemical energy, so they are the opposite of voltaic cells,in an electrolytic cell, the cathode is negatively charged and the anode is positively charged
M=(mols/L) so M=(9.0/2.5) which is 3.6M
