Answer : The angular acceleration is 
Solution : Given,


The given angular velocity equation is,

At t = 0, 
At t = t, 
Angular acceleration : It is defined as the rate of change of angular velocity with respect to time.
Formula used for angular acceleration :

where,
= angular acceleration
= angular velocity at time 't'
= angular velocity at time '0'
t = time
Now put all the given values in this formula, we get the angular acceleration.


Therefore, the angular acceleration is 
Answer:
H⁺(aq) + OH⁻(aq) ⇒ H₂O(l)
Explanation:
Let's consider the molecular equation that occurs when aqueous solutions of perchloric acid and potassium hydroxide are combined. This is a neutralization reaction.
HClO₄(aq) + KOH(aq) ⇒ KClO₄(aq) + H₂O(l)
The complete ionic equation includes all the ions and molecular species.
H⁺(aq) + ClO₄⁻(aq) + K⁺(aq) + OH⁻(aq) ⇒ K⁺(aq) + ClO₄⁻(aq) + H₂O(l)
The net ionic equation includes only the ions that participate in the reaction and the molecular species.
H⁺(aq) + OH⁻(aq) ⇒ H₂O(l)

Answer:
he atomic size of an atom, also called the atomic radius, refers to the distance between an atom's nucleus and its valence electrons. Remember, the closer an electron is to the nucleus, the lower its energy and the more tightly it is held
