Use lewis dot symbols to show the sharing of electrons between a nitrogen atom and fluorine atoms to form a molecule in which ea
ch atom has an octet of electrons.
2 answers:
Explanation:
Lewis dot structure is the representation of the valence electrons around the atom of an element. it also shows the number of unpaired electrons present in a molecule.
Nitrogen has atomic number of 7 and electronic configuration is given as:
Fluorine has atomic number of 9 and electronic configuration is given as:
Since fluorine is highly electronegative atom.will attract electrons of nitrogen towards itself.So in Lewis dot structure the fluorine atom will present around single nitrogen atom.
The Lewis structure is given in an image attached.

<u>Answer:</u> The mass of produced is 889.38 g
<u>Explanation:</u>
We are given:
Moles of Al = 8 mol
Moles of = 10 mol
For the given chemical reaction:
By stoichiometry of the reaction:
If 3 moles of chlorine gas reacts with 2 moles of Al
So, 10 moles of chlorine gas will react with = of Al
As the given amount of Al is more than the required amount. Thus, it is present in excess and is considered as an excess reagent.
Thus, chlorine gas is considered a limiting reagent because it limits the formation of the product.
By the stoichiometry of the reaction:
If 3 moles of produces 2 mole of
So, 10 moles of will produce =
of
The number of moles is defined as the ratio of the mass of a substance to its molar mass. The equation used is:
We know, molar mass of = 133.34 g/mol
Putting values in above equation, we get:
Hence, the mass of produced is 889.38 g
