Extreme cold which is usually produced by liquid nitrogen. Hope that helps!
Answer:
Condensation is the process of water vapor condensing into liquid water.
Explanation:
"Water condenses on a can of cold soda. Water vapor in the air reaches its dew point as it cools in the air around the can, forming liquid drops of water. Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor." -National Geographic"
Answer:
See explanation
Explanation:
You see, all these materials we see around us are composed of elements. These elements are unique in their own ways!
Some of them are able to attract tiny negative particles called electrons close to their positive interior called the nucleus. This positive interior is so designated because it contains a positive particle called protons which attract these electrons.
Now, elements are broadly divided into metals and non metals. Protons in metallic elements are less able to pull electrons than protons in non metallic elements. As a result of this, non metals are mostly electronegative because they pull electrons towards themselves while metals are mostly electropositive because they give away their electrons easily. Fork is composed of metallic elements.
Since metals give away electrons easily, they can conduct electricity since electrons are the same charge carriers in electric circuits.
Also, in elements, there is a conduction band and a valence band. Electrons occupy the valence band but also move into the conduction band. The gap between the valence band and the conduction band in nonmetals is large hence they do not conduct electricity. The gap between the valence band and the conduction band in metals is minimal hence metals conduct electricity.
So if you stick that fork into a toaster, electrons can flow right through the toaster circuit into your body and cause you to be electrocuted.
-When Ksp is the solubility product constant for a solid substance when it
dissolved in an aqueous solution, and measure the level at which a solute
dissolves in the solution.
- and we have the solubility and it is the maximum quantity of solute which can dissolve in a certain solute
we can assume the solubility = X = 2.2 x 10^-5 M
and when the balanced reaction equation is:
Mn(OH)2(s) ↔ Mn2+ + 2OH-
∴ the Ksp expression is = [Mn2+] [OH-]^2
when [Mn2+] = X = 2.2 x 10^-5 M
and [OH-] = 2X = 2*(2.2 x 10^-5) = 4.4 x 10^-5 M
by substitution:
∴ Ksp = X * (2X)^2
= (2.2 x 10^-5)(4.4 x 10^-5)^2
= 4.3 x 10^-14
