gayaneshka [121]

Answer:

See explanation and image attached

Explanation:

The compound SF4 is sulphur tetraflouride. It has a zero formal charge and has a total of 34 valence electrons.

The central atom in the molecule is sulphur in an sp3d hybridization state hence the molecule has a trigonal bipyramidal electron geometry. Since it is a molecule of the sort AX4E; it gives a see-saw molecular shape.

The structure of the molecule is shown in the image attached to this answer.

What does the atomic number of an element represent?
harkovskaia [24]
Hello!
Whenever you see an atomic number with an element, you know the number of protons in the nucleus of the atom, which determines the chemical of an element and its place on the periodic table.

For example, Hydrogen has only one proton, however, if you were to add say 78 more protons, you'd get gold!

a cadillac escalade has a mass of 2.569 kg if it acceleratesat 4.65m/s what is the net force on the car
alexandr402 [8]
The Net Force is equal to the mass of the Object multiplied by the amount of Acceleration. Therefore, this creates an equation which looks like this:

F = Mass * Acceleration
F = 2.569 kg * 4.65 m/s
F = 11.95 N

Hopes this helps!
