Answer:

The electric force between them decreases

Explanation:

The force between two charged particle is given by :

F=\dfrac{kq_1q_2}{r^2}

Where

r is the distance between charges

If the distance between the charges is increased, the electric force gets decreased as there is an inverse relation between force and distance.

Hence, the correct option is (c) "The electric force between them decreases"

Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,

 

                Less than 0.4 then it is Non Polar Covalent

                

                Between 0.4 and 1.7 then it is Polar Covalent 

            

                Greater than 1.7 then it is Ionic

 

For Na and Cl,

                    E.N of Chlorine       =   3.16

                    E.N of Sodium        =   0.93

                                                   ________

                    E.N Difference             2.23          (Ionic Bond)


For C and O,

                    E.N of Oxygen       =   3.44

                    E.N of Carbon        =   2.55

                                                   ________

                    E.N Difference             0.89          (Polar Covalent Bond)


For N and Cl,

                    E.N of Chlorine      =   3.16

                    E.N of Notrogen     =   3.04

                                                   ________

                    E.N Difference             0.12           (Non-Polar Covalent Bond)


For B and O,

                    E.N of Oxygen        =   3.44

                    E.N of Boron           =   2.04

                                                   ________

                    E.N Difference             1.40          (Polar Covalent Bond)

How to calculate the mass of copper
faust18 [17]

You can acquire the atomic mass of any chemical element by using the periodic table. I've provided an example on a document below to help you identify the components of an <em>element </em>block from the periodic table. Now if you want to find the mass of an exact amount of a substance you use moles for that. That's why it's called molar mass. To find the molar mass of a substance follow this little guide:

  1. Start with the number of grams of each element given.
  2. Convert the mass of each element to moles utilizing the molar mass from the periodic table.
  3. Divide each mole value by the smallest number of moles deciphered.
  4. Round your answer. This is the mole ratio of the element.

*Use the third document I've inserted below to follow the guide.
