5 Crystals of sodium chloride were prepared by the following method. 1 25.0 cm of dilute hydrochloric acid was accurately measured into a conical flask. 2 Aqueous sodium hydroxide was added until the solution was neutral. The volume of sodium hydroxide added was measured. 3 The solution was evaporated and the crystals washed with approximately 15 cm of water. Which row shows the pieces of apparatus used to measure the 25.0 cm of hydrochloric acid, the volume of aqueous sodium hydroxide and the 15 cm of water? 25.0cm of hydrochloric acid accurately the volume of aqueous sodium hydroxide added 15cm of water approximately А burette pipette measuring cylinder B measuring cylinder burette pipette C pipette burette measuring cylinder D pipette measuring cylinder burette odlida is in water​

the role of the microscope world in creating new materials .

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.
