Answer:
Rubber is an insulator.
Remaining three are metals and hence conductors.
Answer:
Electrolyte
Explanation:
A compound that conducts electricity when dissolved in water would most likely be classified as electrolyte.
The ionic compound in solid form do not conduct the electricity but when dissolve in water they separated into ions and have ability to conduct the electricity because of mobile ions that move freely and allow the charge to flow.
The ionic compounds are called electrolyte and electrolyte solution is formed when they dissolve in water.
For example when sodium chloride is placed into water it split into ions and conduct electricity because of mobile ions.
Chemical equation:
NaCl → Na⁺ + Cl⁻
Osmotic pressure is the pressure that would have to be applied to a pure solvent to prevent it from passing into a given solution by osmosis.
That can be mathematical computed from the expression:
Osmotic pressure=C×R×T
Where,
C= Concentration
R=Gas constant
T=Temperature
Concentration=Number of moles of solute/Volume(L)
=0.005*1000/100
=0.05
R= 0.08206 atm L/mol K
T=25+273
=298
Osmotic pressure= 0.05×0.08206×298
=1.2 atm
