The atom will gain 3 electrons
<h3>Further explanation</h3>
Valence electrons are electrons that are used to bond which are located in the outer shell of the atom
The electron configuration of N :
[He] 2s² 2p³
This configuration shows that there are 5 valence electrons in the outer shell of the N atom
So based on the octet rule, the N atom will bind 3 more electrons to make it stable
An example is the formation of covalent (triple) bonds in the formation of N2 molecules
Answer:
A. Refracted
Explanation:
Incident rays parallel to the optical axis are reflected from the mirror.
Answer:
Explanation:
The equation tells you that for every mol of H2 you need 2 mols of Na to get it.
1 H2 / 4 mols H2 = 2 mols Na / x Cross multiply
1*x = 4 * 2
x = 8 mol Na
Answer:
<h3>The answer is 223.0 cm³</h3>
Explanation:
To find the volume when the pressure is at 202.6 kPa we use Boyle's law which is
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we are finding the final volume
From the question
P1 = 99.3 kPa = 99300 Pa
V1 = 455 cm³
P2 = 202.6 kPa = 202600
So we have
We have the final answer as
<h3>223.0 cm³</h3>
Hope this helps you
Yes this is safe, bc he used the tongs and puts it next to the bowl of cold water
