Which of the following molecules, having a bond with chlorine, contains an ionic bond? Chlorine gas, Calcuim Chloride, Carbon Te
natka813 [3]

Answer: In calcium chloride there is one calcium atom and two chloride atoms attached to it, it has an ionic bond with chlorine and calcium. A bond is said to be an ionic bond if it is formed by the electrostatic attraction between one negatively charged and one positively charged ions. Ions are the atoms which are formed on the gain or loss of electrons to an atom. All the other molecules have covalent bonds, which forms on sharing of electron pairs.

Answer:

The answer to your question is: kc = 6.48

Explanation:

Data

             Given                 Molecular weight

CaO =    44.6 g                    56 g

CO₂ =     26 g                       44 g

CaCO₃ = 42.3 g                  100 g

Find moles

        CaO                 56 g ----------------  1 mol

                                 44.6 g --------------   x

                               x = (44.6 x 1) / 56 = 0.8 mol

        CO₂                 44 g -----------------  1 mol

                                26 g ----------------    x

                               x = (26 x 1 ) / 44 = 0.6  moles

        CaCO₃            100 g ---------------   1 mol

                                42.3g --------------    x

                              x = (42.3 x 1) / 100 = 0.423 moles

       

Concentrations

 

        CaO     =    0.8 / 6.5  = 0.12 M

         CO₂    =     0.6 / 6.5 = 0.09 M

        CaCO₃  =   0.423 / 6.5 = 0.07 M

Equilibrium constant =   \frac{[products]}{[reactants]}

Kc = [0.07] / [[0.12][0.09]

Kc = 0.07 / 0.0108

kc = 6.48
