Answer:
the equilibrium bond length of H137I is
Explanation:
The quantum state has a rotational energy which can be expressed mathematically
Here,
B is the rotational constant given as
We are given from the question that
Substituting we have
Where,
h is plank constant
r is radius
I is moment of inertia
Making the subject
The moment of inertia = Reduced mass ×
Therefore
Making the subject of the formula
Molar mass CaCl₂ = 111.0 g/mol
number of moles:
n = mass of solute / molar mass
n = 85.3 / 111.0
n = 0.7684 moles of CaCl₂
M = n / V
0.788 M = <span>0.7684 / V
</span>
V = 0.7684 / 0.788
V = 0.97512 L
hope this helps!
Answer:
All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons.
Explanation:
Answer=3
The compound has an ionic bond.
