Choose the heterogeneous mixture from the list below. choose the heterogeneous mixture from the list below. carbon (graphite) sports drink fluorine gas lasagna cola

Option (d) is the correct answer.

Explanation:

A heterogeneous mixture is defined as the mixture in which solute particles are unevenly distributed into the solvent.

For example, in lasagna particles are not evenly distributed so it is a heterogeneous mixture.

A homogeneous mixture is defined as the mixture in which solute particles are evenly distributed in a solvent.

A homogeneous mixture is a clear solution.

For example, graphite, sports dink, fluorine gas and cola all contains evenly distributed solute particles.

So, all of them are homogeneous mixtures.

Thus, we can conclude that out of the given option lasagna is a heterogeneous mixture.

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.
