Ok, so I will list some physical properties you can take advantage of then explain: magnetism, solubility, also density which adds onto solubility.

So basically if you have a mixture of something like idk bits of wood and bits of something magnetic like iron then you can use a big and strong magnet to separate the iron from the wood.

Solubility, so like I said this goes along with density. If you pour something non-soluble into a solution you can use filtration to get the solute out. So something along the lines of putting fresh tea leaves into a teacup. The leaves don't dissolve so you can use a filter to get them out.

Density, idk if you have ever done an experiment with oil and water where you layer the densities, well you can take advantage of that. So in the ocean fish and stuff kick up sand off the ocean floor. Eventually, the sand falls to the bottom of the ocean because it is denser than water. So yeah.

You can basically separate sand and small pieces of magnets by using a metal to extract the magnets

Answer from: Quest

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.

Nonmetal are moldable and easily shaped
