Answer:
evaporation
Studies have revealed that evaporation—the process by which water changes from a liquid to a gas—from oceans, seas, and other bodies of water
Explanation:
Answer:
<h2>12.1 </h2>
Explanation:
Since the pH has been given, the pOH can be found by using the formula
pH + pOH = 14
pOH = 14 - pH
From the question we have
pOH = 14 - 1.9
We have the final answer as
<h3>12.1</h3>
Hope this helps you
Answer:
Metallic bonding is found in metals and their alloys. When the atoms give up their valence electrons, they form ions. These ions are held together by the electron cloud surrounding them. Metals are shiny because they have a lot of free (i.e. delocalized) electrons that form a cloud of highly mobile negatively charged electrons on and beneath the smooth metal surface in the ideal case. ... In the absence of any external EM field, the charges in the plasma are uniformly distributed within the metal.
Explanation:
In metallic bonding, the electrons are “surrendered” to a common pool and become shared by all the atoms in the solid metal.
Answer: pH of an 
solution is 4.34
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
Putting in the values:
![pH=-\log[4.58\times 10^{-5}]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5B4.58%5Ctimes%2010%5E%7B-5%7D%5D)
Thus pH of an solution if the ![[H^+]](https://tex.z-dn.net/?f=%5BH%5E%2B%5D)
is ![4.58\times 10^{-5}]](https://tex.z-dn.net/?f=4.58%5Ctimes%2010%5E%7B-5%7D%5D)
is 4.34
