Answer:
[ N₂(g) ] = 0.016 M
Explanation:
N₂(g) + 3 H₂(g) ↔ 2 NH₃(g)
The equilibrium constant for the above reaction , can be written as the product of the concentration of product raised to the power of stoichiometric coefficients in a balanced equation of dissociation divided by the product of the concentration of reactant raised to the power of stoichiometric coefficients in the balanced equation of dissociation .
Hence ,
Kc = [ NH₃ (g) ]² / [ N₂(g) ] [ H₂(g) ]³
From the question ,
[ NH₃ (g) ] = 0.5 M
[ N₂(g) ] = ?
[ H₂(g) ] = 2.0 M
Kc = 2
Now, putting it in the above equation ,
Kc = [ NH₃ (g) ]² / [ N₂(g) ] [ H₂(g) ]³
2 = [ 0.5 M ]² / [ N₂(g) ] [ 2.0 M ]³
[ N₂(g) ] = 0.016 M .
Answer:
So since there are 16 electrons in sulfur and the first layer of electrons in an orbital shell has a max of two, the first layer will be full. The second layer has a max of 8, so that will also be full. The third layer also has a max of 8 but will not get filled up since there are only 6 electrons left. These are the valence electrons. The orbital diagram will usually look like this:
( O = nucleus, . o = electron)
o o
o O o o
o
Answer:
the average kinetic energy of a system
Explanation:
the more kinetic energy in something, the hotter it is, the less kinetic energy in something, the cooler it is. gases have the most kinetic energy. solids have the least, but everything has kinetic energy
I think it’s b?! have a good day!
There are many things that we do in our daily lives that involve energy changes. For example ,when you hold your textbook in the air, you are giving it potential energy. Another example is an object in simple harmonic motion. Energy is constantly being transferred from one from to another, potential to kinetic.
