Answer : The number of moles of and
at equilibrium is, 1.75 mol and 0.87 mol respectively.
Explanation :
The given chemical reaction is:
Initial mol. 3.67 1.83 0
At eqm. (3.67-2x) (1.83-x) 2x
As we are given:
Number of moles of at equilibrium = 1.92
That means,
2x = 1.92
x = 0.96 mol
Number of moles of at equilibrium = (3.67-2x) = [3.67-2(0.96)] = 1.75 mol
Number of moles of at equilibrium = (1.83-x) = (1.83-0.96) = 0.87 mol
Thus, the number of moles of and
at equilibrium is, 1.75 mol and 0.87 mol respectively.
Answer:
Valency of the two elements
Explanation:
In order to correctly formularize the compound, the student needs to ask of the valences of the elements involved.
Chlorine has valency of -1, while Barium +2.
The exchange of valency gives the formula .
Another explanation is that Barium donates 2 electrons which the chlorine atoms accept, in order to form the covalent bond.
