Answer:
See explanation below
Explanation:
In this case, we have the equilibrium reaction which is:
H₂ + I₂ <------> 2HI Kp = 54
Now, we have the partial pressures of each element in equilibrium, therefore, we can use the expression of equilibrium in this case to calculate the remaining pressure:
Kp = PpHI² / PpH₂ * PpI₂
Solving for the partial pressure of iodine:
PpI₂ = PpHI² / PpH₂ * Kp
Replacing the given values, we have:
PpI₂ = (2.1)² / 0.933 * 54
PpI₂ = 4.41 / 50.382
PpI₂ = 0.088 atm
Answer:

Explanation:
R = Rydberg constant = 
= Principal quantum number of an energy level = 2
= Principal quantum number of an energy level for the atomic electron transition = 4
Wavelength is given by the Rydberg formula

The wavelength of the light emitted is
.
They eat autotrophs, or each other. That's how they get energy.

The number of moles of H atoms in 15.2 grams of pure ice is 0.850 moles
The number of moles of O atoms in 15.2 grams of pure ice is 13.50 moles
<h3>What is an atom?</h3>
An atom is a smallest indivisible particle of a chemical element that is capable of independent existence.
- Pure ice contains the H2O molecules and the molar mass of H2O is 18.02 g/mol
Using the relation:
- number of moles = mass/molar mass
The number of moles of H2O = 15.2 grams/18.02 g/mol
number of moles of H2O = 0.8435 moles
If the atomic mass of H and O are as follow:
- the atomic mass of H atom is = 1.00784 g/mol
- the atomic mass of O atom is = 15.999 g/mol
Then:
the number of H atoms in 15.2 grams of pure ice = mass of H atom × molar mass of H2O.
the number of H atoms = 0.8435 mol × 1.00784 g/mol
the number of H atoms = 0.850 moles
the number of O atoms in 15.2 grams of pure ice = 0.8435 mol × 15.999 g/mol
the number of O atoms = 13.50 moles
