Answer:
A metal and a non-metal
Explanation:
Ionic bonds are formed between two or more atoms by the transfer of one or more electrons between atoms. Electron transfer produces negative ions called anions and positive ions called cations.
Br₂ + FeBr₃----->Br-Br-FeBr₃
In this reaction, FeBr₃, is a electron-deficient species that is it act as a lewis acid.
While Br₂, donates its electron to FeBr₃.
Br₂, act as a electrophile while FeBr₃ is a lewis acid.
Futher if Br₂, undergoes a reaction an aromatic ring , then that ring will attack Br₂, and it acts as a electrophile.
Double indemnity protection provides double benefits if death is the result of an accident.
the answer is d)
They are not allike as na atom has 11 elctrons and Na ion has 10 electons. <span>They both have the same nucleus (same number of protons and neutrons). The only difference is that the ion has one less electron than the atom (in this case).</span>
Answer:
magnetite
Explanation:
proportion of iron in haematite = 3.5/5 x 100% = 70%
proportion of iron in magnetite = 7.2/10 x 100% = 72%
