Answer:
Ionization energy of is 54.4 eV.
Explanation:
where,
= energy of orbit
n = number of orbit
Z = atomic number
Energy of n = 1 in an hydrogen like atom:
Energy of n = ∞ in an hydrogen like atom:
Ionization energy of =
The forces between particles are called intermolecular forces. A strong intermolecular force means that the particles are tightly paced and is associated with the solid phase. Moderate intermolecular force is associated with the liquid state and little to no intermolecular force is associated with the gaseous state. Temperature has a direct effect on the state of matter in which the substance exists has. Generally speaking, a rise in tempreature changes a substance from the solid to liquid phase and from liquid to gaseus phase. The reverse is true, if the temperature lowers then the substance will go from gas to liquid and liquid to solid. It is important to not that temperature affects intermolecular forces. As the temperature increases then the individual particles become excited and gain enough energy to over the intermolecular forces and so the particles seperate from each other.
Answer:
V₁ = 31.5 mL
Explanation:
Given data:
Initial molarity = 2.50 M
Initial volume required = ?
Final molarity = 0.150 M
Final volume = 525 mL
Solution:
Formula:
M₁V₁ = M₂V₂
M₁ = Initial molarity
V₁ = Initial volume
M₂ = Final molarity
V₂ = Final volume
Now we will put the values in formula.
2.50 M × V₁ = 0.150 M × 525 mL
V₁ = 0.150 M × 525 mL/ 2.50 M
V₁ = 78.75 M.mL/ 2.50 M
V₁ = 31.5 mL
