*plz this is urgent* which of the following chemical formula shows an ionic compound? a. c6h12o6 b. n2o c. naci d. co2

            Option-C (NaCl) is the correct answer.

Explanation:

                   Ionic compounds are those compounds which are made up of oppositively charged ions held together strongly by Ionic bonds. The main reason of formation of ionic bond between two atoms is the electronegativity difference of more than 1.7 between them. Therefore, the electronegativity difference between Sodium and Chloride ions in NaCl is calculated as,

                                        E.N of Chlorine    =       3.16

                                        E.N of Sodium      =      0.93

                                        Difference                     2.23

As the difference is greater than 1.7 hence, the bond will be ionic in nature.

While other all compounds are covalent in nature.

answer; ///(d) the correct answer is double or triple

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
