Answer:
Charles Law
Explanation:
Charles's law (also known as the law of volumes) is an experimental gas law that describes how gases tend to expand when heated. A modern statement of Charles's law is: This relationship of direct proportion can be written as: V∝T

Angular quantum number
Magnetic quantum number
Spin quantum number
Explanation:
Answer:
9
Explanation:
n-factor of NaOH = 1
OH⁻ concentration = Normality of NaOH
= Molarity x n-factor
= 10⁻⁵ x 1
= 10⁻⁵
Now, pOH = -㏒(OH⁻)
pOH = -㏒(10⁻⁵)
pOH = 5
We know pH + pOH = 14
pH = 14 - 5 = 9
∴pH of 10⁻⁵M NaOH is 9
The answer is "chemical properties". The original water is split apart by the current
<span>to form its constituent elements, hydrogen & oxygen. This is a chemical change, as </span>
<span>the original water is lost and new substances, H2 & O2, are produced. </span>
<span>Hope this answers your question.</span>
