Explanation:
Answer:
5.0
Explanation:
We have a buffer system formed by a weak base (C₅H₅N) and its conjugate acid (C₅H₆N⁺). We can calculate the pOH using the Henderson-Hasselbach's equation.
pOH = pKb + log [acid]/[base]
pOH = -log 1.8 × 10⁻⁹ + log 0.02/0.01
pOH = 9.0
Then, we will calculate the pH.
pH + pOH = 14
pH = 14 - pOH = 14 - 9.0 = 5.0
An intrinsic property is independent of how much of a material is present and is independent of the form of the material, one large piece or a collection of small particles. Intrinsic properties are dependent mainly on the fundamental chemical composition and structure of the material.
Answer:
A detonated nuclear bomb produces a fireball, shockwaves and intense radiation. A mushroom cloud forms from vaporized debris and disperses radioactive particles that fall to earth contaminating air, soil, water and the food supply. When carried by wind currents, fallout can cause far-reaching environmental damage
Explanation:
They harness the forces that hold the nucleus of an atom together by using the energy Nuclear fission produces the atomic bomb, a weapon of mass destruction that uses power released by the splitting of atomic nuclei. to initiate a nuclear fusion reaction, the process is often referred to as a thermonuclear explosion.

Molarity is used to measure the concentration of a solution , so it is also as molar concentration. It is denoted as M or Mol/L
<u>We </u><u>are </u><u>given </u><u>that </u><u>:</u>
- Weight of = 5.34g
- Volume of solution = 214 ml , or 0.214 L
The molar mass of magnesium chloride ( ) is 95.21 g / mol
We can calculate the molarity of the solution by dividing the number of moles of solute by volume of solvent in liter ,i.e:
ㅤㅤㅤ⸻( 1 )
<em>Where,</em><em> </em>
- M = molarity
- n = number of moles
- V = Volume
We can calculate the number of moles by dividing the actual mass by its molar mass ,i.e:
ㅤㅤㅤ⸻ ( 2 )
<em>W</em><em>here,</em>
- n = number of moles
- m = molar mass
- w = actual mass
