Answer : The length of a one-dimensional box for an electron is 
Explanation :
The energy level of quantum particle in a one-dimensional box is given as:
where,
= 479 kJ/mol = 479000 J/mol
n = energy level = 1
h = Planck's constant = 
m = mass of electron = 
L = length of a one-dimensional box = ?
Now put all the given values in the above formula, we get:
conversion used : 
Therefore, the length of a one-dimensional box for an electron is
<em>Answer:</em>
- The atom have a full valence electron shell.
<em>Explanation:</em>
- My question is that why covalent bonds take place?
Every atoms tends to from bond with another atoms in order to get nearest electronic configuration of nobel gases. They become stable when their valence shell become complete. So when covelant bond forms between atoms, share electrons to each other and stabilize themselves.
3,5, and 1 i think maybe i uhm yeah
All colors but red is being absorbed by the material.
Answer: The corresponding value of 
for this reaction at 84.5°C is 0.00232
Explanation:
Relation of with is given by the formula:
where,
= equilibrium constant in terms of partial pressure = ?
= equilibrium constant in terms of concentration = 0.0680
R = Gas constant = 
T = temperature =
= change in number of moles of gas particles = 
Putting values in above equation, we get:
Thus the corresponding value of for this reaction at 84.5°C is 0.00232
