Halogens

Explanation:

Halogens are a group of non-metals located in the seventh group on the periodic table. The will only gain one electron during a chemical reaction.

  • Halogens have a seven electrons in their outermost shell.
  • To complete the number of electrons in this shell, they need to gain an additional electron.
  • One more electron makes the halogen similar to the corresponding noble gas which is very stable.
  • Halogens are very reactive groups of elements and are highly electronegative.
  • They have a high affinity for electrons.
  • These elements are fluorine, chlorine, bromine, iodine and Astatine.

77julia77 [94]

Answer:

Magnetism is believed to be caused by the alignment of small, numerous sub-units called : <em><u>Domains</u></em>

<em><u></u></em>

Explanation:

Domains : A magnetic domain is the region in which in which magnetic field of the atoms are grouped together and aligned.

  • In unmagnetized material all the magnetic Domains  point in different direction.
  • In magnetised material (ferromagnets , antiferromagnets) , The Domains point in a particular( fixed Pattern) direction.

Calculate the equilibrium constant at 25 ∘C for the reaction Fe(s)+2Ag+(aq)→Fe2+(aq)+2Ag(s)
Murrr4er [49]

Answer:

1.7 × 10 ^42

Explanation:

Using Nernst equation

E°cell = RT/nF Inq

at equilibrium

Q=K

E°cell  = 0.0257 /n Ink= 0.0592/n log K

Fe2+(aq)+2e−→Fe(s)     E∘= −0.45 V

Ag+aq)+e−→Ag(s)         E∘= 0.80 V

Fe(s)+2Ag+(aq)→Fe2+(aq)+2Ag(s)

balance the reaction

Fe → Fe²⁺ + 2e⁻  reversing for oxidation E° = 0.45 v

2 Ag⁺ +2e⁻ → 2Ag

n = 2 moles  and K = equilibrium constant

E° cell = 0.80 + 0.45 = 1.25 V

E° cell = (0.0592 / n) log K  

substitute the value into the equations and solve for K

(1.25 × 2) / 0.0592  = log K

42.23 = log K

k = 10^ 42.23

K = 1.7 × 10 ^42
