Silicon Tetrachloride is reacted with very pure magnesium, producing silicon and magnesium chloride. (What would be the unbalanc
raketka [301]
Pure magnesium's formula would just be Mg because all elements except for 7 nonmetals are just left alone when they are by themselves in a formula. The 7 diatomic elements( means they have to have two of them without another element attached to it aka. a subscript two after it when it's by itself) are hydrogen, nitrogen, oxygen, fluorine, chlorine, bromine, and iodine. An easy way to remember the diatomic seven is that when looking at a periodic table if you trace over them from nitrogen over to fluorine and down to iodine all of those elements are diatomic + hydrogen. 

And your unbalanced and balanced equations are correct.

(sorry I went on a tangent with the diatomic rules hopefully it will help you in the future though)

Provide an orbital energy level diagram for the geound state of a nitrogen atom.
Alenkasestr [34]

Answer:

A

Explanation:

Nitrogen is an atom made up of 7 electrons.

To draw the orbital energy level diagram, let us write the orbital notation of the atom;

  7 electrons of Nitrogen:

        1s² 2s² 2p³

So,

 The orbital notation diagram is :

            1s²         2s²          2p³

            ↑↓          ↑↓          ↑↑↑

What kind of bonds are hydrogen bonds???
34kurt

Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.

Does changing the amplitude affect the period on a pendulum and how
yawa3891 [41]

Answer:

As the amplitude of pendulum motion increases, the period lengthens, because the restoring force −mgsinθ increases more slowly than −mgθ (sinθ≅θ−θ3/3!for small angles).
