Ionic bonds involve a cation and an anion. The bond is formed when an atom, typically a metal, loses an electron or electrons, and becomes a positive ion, or cation. Another atom, typically a non-metal, is able to acquire the electron(s) to become a negative ion, or anion.

One example of an ionic bond is the formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom. In this reaction, the sodium atom loses its single valence electron to the fluorine atom, which has just enough space to accept it. The ions produced are oppositely charged and are attracted to one another due to electrostatic forces.

What are the strengths and limitations of a cell?

Cells have limitations, if the cell is stronger it targets other cells , when a cell is weak it possibly mean it’s disease.

Carbon tetrachloride reacts at high temperatures with oxygen to produce two toxic gases, phosgene and chlorine.CCl4(g) + (1/2)O2

Elodia [21]

Answer : The value of $K'_c$ for the reaction is, $1.9\times 10^{19}$

Explanation :

The given equilibrium reactions are:

(1) $CCl_4(g)+\frac{1}{2}O_2(g)\rightleftharpoons COCl_2(g)+Cl_2(g)$ $K_c=4.4\times 10^9$

(2) $2CCl_4(g)+O_2(g)\rightleftharpoons 2COCl_2(g)+2Cl_2(g)$ $K'_c=?$

As we know that, when we are multiplying the equation (1) by 2 then we get the equation (2). Thus, the relation between the two equilibrium constant will be,

$K'_c=(K_c)^2$

So,

$K'_c=(4.4\times 10^9)^2$

$K'_c=1.9\times 10^{19}$

Therefore, the value of $K'_c$ for the reaction is, $1.9\times 10^{19}$
