Answer : % ionic character is 0.20%
Bonding between the two metals will be purely metallic.
Explanation: For the calculation of % ionic character, we use the formula
where &
are the Pauling's electronegativities.
The table attached has the values of electronegativities, by taking the values of Al and Mn from there,
Putting the values in the electronegativity formula, we get
= 0.20%
Now, there are 3 types of inter atomic bonding
1) Ionic Bonding: It refers to the chemical bond in which there is complete transfer of valence electrons between atoms
2) Covalent Bonding: It refers to the chemical bond involving the sharing of electron pairs between 2 atoms.
3) Metallic Bonding: It refers to the chemical bond in which there is an electrostatic force between the positively charged metal ions and delocalised electrons.
In compound, the % ionic character is minimal that is
0.20% and there are two metal ions present, therefore this compound will have metallic bonding.
Answer:
The molecular formula of benzene =
Explanation:
% of C = 92.3
Molar mass of C = 12.0107 g/mol
% moles of C = = 7.6848
% of H = 7.7
Molar mass of H = 1.00784 g/mol
% moles of H = = 7.6401
Taking the simplest ratio for C and H as:
7.6848 : 7.6401
= 1 : 1
The empirical formula is =
Molecular formulas is the actual number of atoms of each element in the compound while empirical formulas is the simplest or reduced ratio of the elements in the compound.
Thus,
Molecular mass = n × Empirical mass
Where, n is any positive number from 1, 2, 3...
Mass from the Empirical formula = 12+ 1 = 13 g/mol
Molar mass = 78.0 g/mol
So,
Molecular mass = n × Empirical mass
78.0 = n × 13
⇒ n ≅ 6
