A student wants to make 125 mL of a 0.050 M beryllium chloride solution. a) Calculate the number of grams of beryllium chloride necessary to make the solution.

b) Describe, in detail, how would you make this solution using the appropriate equipment.

c) After the student made the solution, he mixes it with a 2.5 M Pb(NO3)2 solution. Write the net ionic equation for this reaction.

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.

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.
