Answer:

[He]2p6

Explanation:

Fluorine has an atomoc number of 9 which means 9 electrons with the electon configuration:[He]2p5,However,when it becomes Fluoride ion,it gains one electron to complete its outermost shell to obtain an octet configuration and becomes [He]2p6.

How many valence electrons does the Lewis structure for a chlorine atom show
ohaa [14]

Answer: D

Explanation:

Chlorine is in group 7 or (VII) in Roman numerals, which means it has 7 balance electrons. It only needs one electron to become stable, hence it is next to the noble gases

What purpose does fecl3 serve in the electrophilic aromatic substitution reaction between chlorine and benzene?
maria [59]
The reason does FeCl3 serve in the electrophilic sweet-smelling substitution response amongst chlorine and benzene is that it fills in as a Lewis corrosive impetus by responding with the Cl2 and along these lines actuates it toward assault by benzene's π electrons.

Nitrogen and oxygen form an extensive series of oxides with the general formula NxOy. One of them is a blue solid that comes apa
Marizza181 [45]

Work out the number of moles in

100.00 grams of the oxide.

For nitrogen: The atomic mass of N is 14.0067, and we have 36.84 g N:

36.84 g N14.0067 g N/mol N=2.630 mol N

For oxygen: The atomic mass of O is

15.9994, and we have

100.00−36.84=63.16 g O:

63.16 g N 15.9994 g N/mol N=3.948 mol N

Now the ratio 3.958 2.630 is very close to

1.5=32

. So we conclude that the gas has three moles

O to two moles N making the empirical formula

N2O3.

Using the equation 2H2 + O2 --&gt; 2 H2O, if 192 g of O are produced, how many grams of hydrogen must react with it? Help me und
Mamont248 [21]
<span>To produce a molar conversion, you need to know the molar mass of each molecule. I presume you mean there are 192 grams of O2. The molecular weight of oxygen is 16 g/mol. Therefore, O2 is 32 g/mole.

   If there are 192 grams of O2, then:
 192 grams x (1 mole/32g) = 6 moles of O2.

   To react each mole of oxygen, you need 2 moles of hydrogen (H2). You can see this in the equation 2H2 + O2 --> 2 H20.
   To react 6 moles of O2, you need 12 moles of H2.
   Now that we have the total moles of hydrogen needed, we now use the molar mass of H2 (2 grams/mole)
   12 moles H2 x (2 grams/1 mol H2) = 24 grams of H2.</span>
