In water, mgcl2 dissociates into mg2+ and cl-. Based on this information what type of bond is involved in the formation of mgcl2
s344n2d4d5 [400]
<h3>Answer:</h3>

              Ionic Bond

<h3>Explanation:</h3>

                     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  Bonding

               Between 0.4 and 1.7 then it is Polar Covalent  Bonding

               Greater than 1.7 then it is Ionic  Bonding

For Mg and Cl,

                   E.N of Chlorine             =   3.16

                   E.N of Magnesium        =   1.31

                                                             ________

                   E.N Difference                     1.85          (Ionic Bond)

<h3>Conclusion:</h3>

                   MgCl₂ being ionic in nature when dissolved in water dissociates into Magnesium and Chloride ions respectively.

A layer of sediment goes through a series of steps on its way to becoming sedimentary rock. These steps are summarized below. Re
gizmo_the_mogwai [7]

Explanation:

The steps involved in formation of a sedimentary rock are placed in the correct order as follows.

Step 1: The sediment is deposited by wind, flowing water, or other natural processes.

Step 2: The sediment is gradually buried and compacted.

Step 3: Dissolved minerals completely cement the sediment together.

As a result, it leads to the formation of a sedimentary rock.
