Answer:
Silver ions.
Explanation:
The most extensively studied nanomaterials for water purification and treatment mainly includes zero-valent metal nanoparticles, metal oxides nanoparticles, carbon nanotubules and nanocomposites.
Answer:-
0.883 m
Explanation:-
Molality= Moles per Kg of solvent.
Molar mass of ethylene glycol= 62.07 g/ mol.
Number of moles of ethylene glycol= 82.2g / (62.07 g/mol)
= 1.324 moles
Density of water = 1 g/ml = (1/1000kg)/ (1/1000litre)
= 1 Kg / litre
Mass of 1.5 litre of water = 1.5 litre x 1 kg / litre
= 1.5 kg
Molality of ethylene glycol = 1.324 moles/1.5 kg
= 0.883 m
Answer:
Boiling: The process of conversion from liquid to gas on heating is called boiling.
Example: Water on heating turns into water vapour.
Melting: The process of conversion from solid to liquid at room temperature is called melting.
Example: Ice cream melting at room temperature.
Sublimation: The Conversion of solid to gas directly is called sublimation.
Example: Camphor, Dry ice

Answer:
To have a high electrical conductivity, a normal metal should have mobile valence electrons and a long electron mean free path.
Explanation:
A long mean free path means that the electron goes a long distance between scattering events.
