Conductivity is the ability of a substance to allow charge or electricity to pass through it. Metals have a lot of free electrons and are considered as good conductors while non-metals do not conduct electricity
1) In the given examples:
Al is a metal, Na is an alkali metal while P is a non-metal
The decreasing order of conductivity would be:
Al > Na > P
2)
Both Al and Ga are metals while B is metalloid.
Among Al and Ga, Al is a solid at room temperature and a better conductor of electricity. hence the decreasing order would be:
Al > Ga > B
The ammonium ion is NH4+ which should have a molecular weight of 18g/mol. Then, the amount of ammonium ion in mol should be <span>7.65g/ (18g/mol)= 0.425 mol.
The formula for ammonium sulfate would be </span>(NH4)2SO4. For every ammonium sulfate, you need 2 ammonium ion. Then the amount of ammonium sulfate in mol should be: 0.425 mol * (1/2)= 0.2125mol
The volume of the solution would be: 0.2125mol/ (0.812 mol/liter)= 0.26169l= 261.70 ml
Answer:
Volume is directly proportional to absolute temperature.
