What is plasma and where can you find it

Plasmas are a common part of the world we live in. The definition of plasma allows them to exist within an environment consisting mostly of bound atoms.

A variety of human technology creates plasmas. The type I hear plasma researchers reference most is a simple RF Plasma. This is perhaps the most direct way to use electricity to shake off the electrons from their atoms within a confined volume by using fast oscillating electromagnetic fields.

Nature also creates plasma. An Aurora is certainly included. Many less "exotic" plasma states are much more common. A fire has a low population of the ionized species, but is still a plasma.

See Wikipedia for a list of available plasmas over there..! Or have a look below for the chart which shows variation of temperature and electron density in different plasmas..!

Plasmas

A quick Googling would've provided the answer. Common examples include

Lightning..!

The Sun (from Core to Corona)

Fluorescent Lights and Neon Signs

Nebulae (Luminous Clouds in Space)

The Solar Wind

Primordial Fusion during the evolution of the Universe

Magnetic Confinement Fusion Plasmas

Inertially Confined Fusion Plasmas

Flames as Plasmas

Auroras (Northern & Southern Lights)

Interstellar Space (It's not empty... It's a plasma)

Quasars, Radiogalaxies, and Galaxies (Emit plasma radiation and microwaves)

Large Scale Structures of Galaxies (Filamentary and magnetized..!)

Dense Solid State Matter (When shocked by nuclear explosion or earthquakes which emit both visible light and radio waves)

Plasmas are a lot like gases, they are made up of free electrons and ions of an element such as neon (Ne). You don't find naturally occurring plasmas too often when you walk around. They aren't things that happen regularly on Earth.

Which compound reacts with an acid to produce water and a salt
Hatshy [7]
I'm not exactly sure which one but I do know that an acid and a base react in a aqueous solution to form water, so i would probably eliminate the ones that aren't aqueous solutions.

Calculate the mole fraction of kbr (molar mass 119.00 g/mol) in a solution made by dissolving 0.30 g kbr in 0.400 l of H2O (d =
julia-pushkina [17]

The mole fraction of KBr in the solution is 0.0001

<h3>How to determine the mole of water</h3>

We'll begin by calculating the mass of the water. This can be obtained as follow:

  • Volume of water = 0.4 L = 0.4 × 1000 = 400 mL
  • Density of water = 1 g/mL
  • Mass of water =?

Density = mass / volume

1 = Mass of water / 400

Croiss multiply

Mass of water = 1 × 400

Mass of water = 400 g

Finally, we shall determine the mole of the water

  • Mass of water = 400 g
  • Molar mass of water = 18.02 g/mol
  • Mole of water = ?

Mole = mass / molar mass

Mole of water = 400 / 18.02

Mole of water = 22.2 moles

<h3>How to de terminethe mole of KBr</h3>
  • Mass of KBr = 0.3 g
  • Molar mass of KBr = 119 g/mol
  • Mole of KBr = ?

Mole = mass / molar mass

Mole of KBr = 0.3 / 119

Mole of KBr = 0.0025 mole

<h3>How to determine the mole fraction of KBr</h3>
  • Mole of KBr = 0.0025 mole
  • Mole of water = 22.2 moles
  • Total mole = 0.0025 + 22.2 = 22.2025 moles
  • Mole fraction of KBr =?

Mole fraction = mole / total mole

Mole fraction of KBr = 0.0025 / 22.2025

Mole fraction of KBr = 0.0001

What is the volume of 300. g of mercury vapor at 822K and 0.900 atm?
Dominik [7]

Answer:

112.2L

Explanation:

Volume (V) = 300g

Temperature (T) = 822K

Pressure (P) = 0.9atm

using the ideal gas equation;

PV = nRT\\\\ V = \frac{nRT}{P}

Molar gas constant (R) = 0.0821L.atm/mol.K

Mole (n) = \frac{Mass (m)}{Molar mass (M)}                Molar mass of Mercury  = 200.59g/mol

n = \frac{300g}{200.59 g/mol} \\

   = 1.496mol

Now, the volume can be calculated;

V = \frac{1.496mol* 0.0821L.atm/mol.K*822K}{0.9atm}

∴Volume of mercury = 112.2L
