A student is making a model of the layers of Earth. She is using materials with different densities to represent the layers. The table shows the materials she has chosen for two layers. How should the density of the material the student uses for the mantle compare to the density of the materials chosen for the other layers?

It should be more dense than foam.

It should be more dense than glass,

It should be the same density as foam

It should be the same density as glass.

am i too late?

explanation:

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.
