1. Se tiene 360 mL de solución de sulfato de plata con densidad 1,75 g/mL y al 7%, se añaden 250 mL de otra solución de sulfato de plata con una densidad de 1,30 g/mL al 4,5%. ¿Cuál es la concentración M de la nueva solución? 2. Una solución de carbonato férrico al 2,5% en densidad 7,25 g/mL en 750 mL. Calcular las concentraciones M y N

3. Calcular la densidad de una disolución que se ha preparado con 70 g de propílico en 350 mL de agua, con una concentración del 25%.

4. En qué volumen estarán disueltos 0,75 g de carbonato de aluminio que tiene una densidad de 5,25 g/mL al 12%.

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.
