A residential program will help her and other people, who are in the same situation, to change themselves and they will get support from the organizers of the program. </span>
Answer:
To predict the number of shearing electron between the two atoms (ionic bond) the concept of electronegativity is used.In the other words the ability of atoms to attracts the electron is known as electronegativity of the atom.
If the electronegativity between two atoms is greater than 1.7 then these types of bond is known as ionic bond.These types of bond will show ionic character.
Answer:
FeCl₃ is present in excess.
Explanation:
Given data:
Number of moles of FeCl₃ = 6 mol
Number of moles of oxygen = 3 mol
Excess reactant = ?
Solution:
Chemical equation:
4FeCl₃ + 3O₂ → 2Fe₂O₃ + 6Cl₂
Now we will compare the moles of reactant with product.
FeCl₃ : Fe₂O₃
4 : 2
6 : 2/4×6= 3
FeCl₃ : Cl₂
4 : 6
6 : 6/4×6= 9
O₂ : Fe₂O₃
3 : 2
O₂ : Cl₂
3 : 6
Less number of moles of product are formed by the oxygen thus it will act as limiting reactant while FeCl₃ is present in excess.
