When chemical bonds are broken from the environment in which they were made
Answer:
[N₂] = 1.1M
Explanation:
Based on the chemical reaction:
N₂(g) + O₂(g) ⇄ 2 NO(g)
Equilibrium constant, K, is defined as:
K = 5.93 = [NO]² / [N₂] [O₂]
<em>Where [] are equilibrium concentrations of each specie</em>
<em />
As initial concentrations are:
N₂ = 0.40mol / 0.500L = 0.8M
NO = 1mol / 0.500L = 2M
The equilbrium concentrations are:
[NO] = 2M - 2X
[N₂] = 0.8M +X
[O₂] = X
Replacing:
5.93 = [2 - 2X]² / [0.8+X] [X]
5.93 = 4 - 8X + 4X² / 0.8X + X²
4.744X + 5.93X² = 4 - 8X + 4X²
1.93X² + 12.744X - 4 = 0
Solving for X:
X = -6.9M → False solution. There are no negative concentrations
X = 0.3M. Real solution.
[N₂] in equilibrium is:
[N₂] = 0.8M +0.3M
[N₂] = 1.1M
Answer:is D.the wave theory of light
Explanation:
cuz i got it wrong :( but the answer is correct :3
I found the complete question:
Which statement about schrodingers theory of the atomic model is true?
A. it proved that the nucleus of an atom is positively charged.
B. it was the first theory to discuss the existence of electrons.
C. it explained the odds of finding the position of an electron.
D. it assumed the electron cloud to be heavier than the nucleus.
Answer:
C. it explained the odds of finding the position of an electron.
Explanation:
Erwin Schrodinger formulated the wave equation of electrons. His wave equation highlighted the probability of where an electron can be found or located in an energy level.
The region of maximum probability of where an electron is located is referred to as an electron cloud or an orbital.
