Answer:
1. London dispersion
Explanation:
Sulphur trioxide ( SO₃ ) -
The chemical compound SO₃ is planar in structure , the only intermolecular forces shown by SO₃ is the London forces .
dipole - dipole is not observed in this compound , as it is not possible to generate poles between the sulfur and oxygen atom due to very less difference in the electronegativity .
Hydrogen bonding is also not observed , because there is not hydrogen atom .
Hence , only London forces are observed in SO₃ .
Magnesium is in the second group in the periodic table, which means that its outer shell is an s-orbital which contains 2 valence electrons.
Hydrogen also has an s-orbital as an outer shell but it only contains 1 valence electron. The electron dot diagram would look like this:
H· ·Mg· ·H
Each hydrogen shares one electron with magnesium and the magnesium shares one of its electrons with each hydrogen resulting in two covalent bonds.
H:Mg:H and this gives us the compounds MgH₂
Answer: Yea yea please please
Explanation:
No more I don’t have any
Answer:
20%
Explanation:
mass by mass percentage of a solution =(mass of solute)/(mass of solution)
mass of solute=550g
therefore 110×100/550=20%
