What is the chemical formula of calcium chloride?
2 answers:
Explanation:
Atomic number of calcium is 20 and its electronic configuration is 2, 8, 8, 2. So, to acquire stability it loses 2 valence electrons and hence forms ion.
Whereas atomic number of calcium is 17 and its electronic distribution is 2, 8, 7. To attain stability its needs to gain one electron and hence then it forms ion.
Therefore, when both calcium and chlorine chemically combine together then they will form calcium chloride, that is, .
Thus, we can conclude that the chemical formula of calcium chloride is .

Explanation:
The given reaction is as follows.
Value of equilibrium constant is given as = 4.3 \times 10^{6}[/tex].
Concentration of given species is = 0.010 M;
= 10.M;
= 0.010 M.
Formula for experimental value of equilibrium constant (Q) is as follows.
Q =
Putting the given concentration as follows.
Q =
Q =
Q =
It is known that when Q > , then reaction moves in the backward direction.
When Q < , then reaction moves in the forward direction.
When Q = , then reaction is at equilibrium.
As, for the given reaction Q > then it means reaction moves in the backward direction.
Thus, we can conclude that the reaction is moving in the backward direction, that is, right to left to reach the equilibrium.
