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 CaCl₂,

                    E.N of Chlorine       =   3.16

                    E.N of Calcium        =   1.00

                                                   ________

For C-H Bond in C₆H₁₂O₆,

                    E.N of Carbon            =   2.55

                    E.N of Hydrogen        =   2.20

                                                   ________

                    E.N Difference                 0.35         (Non-Polar Covalent Bond)


For C-O Bond in C₆H₁₂O₆,

                    E.N of Oxygen           =   3.44

                    E.N of Hydrogen        =   2.55

                                                   ________

                    E.N Difference                 0.89         (Polar Covalent Bond)


For O-H Bond in C₆H₁₂O₆,

                    E.N of Oxygen           =   3.44

                    E.N of Hydrogen        =   2.20

                                                   ________

                    E.N Difference                 1.24         (Polar Covalent Bond)


For MgO,

                    E.N of Oxygen              =   3.44

                    E.N of Magnesium        =   1.31

                                                   ________

                    E.N Difference                    2.13         (Ionic Bond)


For Na₂O,

                    E.N of Oxygen              =   3.44

                    E.N of Sodium              =   0.93

                                                   ________

                    E.N Difference                    2.51         (Ionic Bond)


For SiO₂,

                    E.N of Oxygen              =   3.44

                    E.N of Silicon                =   1.90

                                                   ________

                    E.N Difference                    1.54         (Polar Covalent Bond)

What leads to the formation of an ionic bond with Hg2+?

The attraction of an SO_4^{2-} ion leads to the formation of an ionic bond with Hg^{2+}

<h3>What is an ionic bond?</h3>

Ionic bond, also called an electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.

Since the question asking among all these options:

(a) The attraction of a noble gas

(b) The attraction of a NH^{4+} ion

(c) The attraction of a group 1 element

(d) The attraction of a SO_4^{2-} ion

An ionic bond can be formed after two or more atoms lose or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons.

Hence, option D is correct.

Temka [501]
The independent variable would be the amount of sunlight because that is what you are testing and the dependent variable would be the length of time the mice slept because it is what you are measuring. The constants would be everything else water, food, cage size, exercise wheel, and temperature because they stay the same.

Answer:The Law of Conservation of Mass simply states that the total amount of mass should not change in a chemical reaction that is isolated (no other objects can enter the reaction). The total mass of the reactants must be equal to the total mass of the products. Thus, the correct estimate of the amount of oxygen used in the interaction is the difference between 133 g and 29 g.
