How does GPS help predict volcanic eruptions? The ground swells slightly before an eruption. GPS devices can detect the swelling.

GPS satellites can see into the cone of the volcano.

The magma carries a GPS device as it travels. Scientists can track the flow of magma by adding more GPS devices to magma.

GPS devices can detect when gases leave a volcano before an eruption.

let that person have a turn to speak : )

explanation:

2b2t

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.
