Since N2 is a covalent bond, the lewis dot structure of  N2 would have a triple bond. Each bond contains 2 electrons, so if it has a triple bond it contains 6 electrons. 
Calculate the number of valence electrons of N2
N= 2x 5 = 10 
N2 has a total of 10 valence electrons, to become stable each N atom needs 8 electrons. 
So, therefore, 6 electrons would have to be a part of covalent bonds because they share 6 electrons in a triple bond.

D. 6 electrons

A single nitrogen atom has five electrons in its outer energy level to start, and will be most stable with an octet, or 8 electrons in its outer level.

Why is only 10% of energy transferred
Alex17521 [72]

Answer:

the rest is lost largely through metabolic processes as heat.

Explanation:

The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level;

The H atom and the Be3³⁺ ion each have one electron. Does the Bohr model predict their spectra accurately? Would you expect thei
lbvjy [14]

Explanation:

a) Bohr model is perfect for atoms that have single electron and fortunately both Be3+ ion and H atom have one electron so, Bohr model can easily and accurately applied to predict the spectrum of Be3+ and H atom.

b) The energy of an atom in  Bohr model is given by

E= \frac{-13.6z^2}{n^2}

the values of z for H atom and Be3+ ion are 1 and 4 respectively. Hence, energy of atoms would be different for both atoms. Hence, line spectra to be identical is not possible.

Ted and Emily played a mixed doubles tennis match against Jack and Brenda. In the second match, Ted and Brenda played against Ja
timofeeve [1]

Answer:

Double replacement.

Explanation:

Chemical Reactions => Double Replacement Reactions.

Let's call Ted as T, Emily as E, Jack as J, and Brenda as B.

In the first match, we have T and E playing against J and B; and in the second match, we have T and B playing against J and E. We can state a 'reaction' of this if the first match would be the reactants and the second match the products:

TE+JB\rightarrow TB+JE.

You can note that this is similar to a double replacement reaction, remember that a double-replacement reaction is a reaction in which the positive and negative ions of two ionic compounds exchange places to form two new compounds. The general form of a double-replacement reaction is:

AB+CD\rightarrow AD+BC,

which is similar to the reaction of the game, so the answer would be Double replacement.
