The right answer is Sodium chloride.
Sodium chloride is a chemical compound whose formula is NaCl. Everyone knows the taste because it is, more simply, table salt.
Let's take a pool 50 meters long and 15 meters wide and fill it with sea water. Then let's go to his analysis. We find:
1400 tons of pure water
50 tons of sodium chloride
2 tons of magnesium
1 ton of sulfur
And then much less frequent elements
Covalent bond is when there is relatively less difference in electronegativity of constituent atoms. On the other hand, ionic bond is formed when there is large difference in electronegativity of constituent atoms.
In present case, electronegativity of F is 3.98, electronegativity of C is 2.55, electronegativity of tin is 1.96 and electronegativity of potassium is 0.82.
Here, since the electronegativity difference is minimum in case of C-F, so covalent bond will be preferentially with carbon.
It must also be noted that neon is an inert gas, hence it will not form bond with F.
Answer: 4.32g
Explanation:
MM of H2 = 1 x 2 = 2g/mol
2g of H2 contains 6.02x10^23 atoms.
Therefore Xg of H2 will contain 1.3 x 1024 atoms i.e
Xg of H2 = (2 x 1.3 x 1024) / 6.02x10^23 = 4.32g
When molality = no.of moles of solute/weight Kg of solvent
and when we have the no. of moles of solute = 8.1 moles
and the weight Kg of the solvent =4847 g /1000 = 4.847 Kg
so by substitution :
Molarity = 8.1m / 4.847Kg = 1.67 M
