I NEED THIS FOR EXAM A template of a Venn diagram representing common and differentiating characteristics of covalent and ionic bonds is shown.

Two overlapping circles are shown. On top of the left-hand circle Ionic Bond is written and on top of the right-hand circle Covalent bond is written. The non-overlapping space on the left is marked A, the overlapping space is marked B and the non-overlapping space on the right is marked C.

Which of the following characteristics can be written only in space B?

Occurs in substances that have at least one non-metal

Occurs in substances that have a repeating lattice structure

Occurs in substances that have discrete molecular structure

Occurs in substances that have high melting points

The characteristic that can be written only in space B is : ( A ) Occurs in substances that have at least one non-metal

The overlapping space of the two circles representing ionic and covalent bonds can be marked as " occurs in substances that have at least one non-metal "  this is because in an ionic bond a metal and a non-metal exchanges their outermost electrons.  while

A covalent bond involves the sharing of outermost electrons by non-metals to attain octet configuration.

Hence we can conclude that the characteristic that can be written only in space B is " Occurs in substances that have at least one non-metal.

Occurs in substances that have at least one non-metal

Explanation:

The overlapping sets which is denoted by the region B is best attributed to connote with the choice "occurs in substance that have at least one non-metal".

To form an ionic bond, a metal and a non-metal must exchange electrons in order to an electrostatic attraction to occur.

In the case of covalent bonds, non-metals shares their valence electrons to form a bond by attaining an octet configuration.

So, we see that a pre-requisite for both bonds to form is a minimum of the presence of a non-metal.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.
