If milk is mixed with gasoline which substance will float

Answer is Gasoline.

Explanation: For determining which substance will float, it can be determined with the values of density.

Density of Milk =

Density of Gasoline =

The one with lower density will float and the one with more will sink.

So here, we can see that the density of gasoline is less therefore, this will float.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
