Determine the initial volume of water in the graduated cylinder. if you added the black marble to the graduated cylinder and it sinks what final volume should the water level indicate?
marble is 14 cm cubed & cylinder initial volume is 105 ml. show the formula on how to arrive at the answer of 124 ml for the final volume so i can understand how to solve these types of problems going forward.
you

Initial volume mentioned = 105mL

Marble volume should be 19mL or  instead of

That is,

Volume of the object (Marble) = Volume of water displaced

= 124 mL - 105 ml = 19 mL

The formula is  

Volume of the object (Marble)

= final volume of water – Initial volume of water

So,

Final volume = Volume marble + Initial volume

= 19 mL + 105 mL = 124 mL  

Please Note: 1mL=

explanation:

2b2t

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.
