A0.060 kilogram ice cube at 0.0 degrees celsius is placed in a glass containing 0.250 kilograms of water at 25 degrees celsius. which statement best describes this system when equilibrium is reached? (assume no external exchange of heat)

1. the ice is completely melted and the water temperature is above 0 degrees celsius

2. the ice is completely melted and the water temperature is 0 degrees celsius

3. part of the ice remains frozen and the water temperature is above 0 degrees celsius

4. part of the ice remains frozen and the water temperature is 0 degrees celsius.

The ice is completely bmelted and the water temperature is above 0 degrees Celsius.

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.
