Zinc reacts with iron (iii) chloride yielding zinc chloride plus iron
olasank [31]

Answer:

I don't see a specific question, so I'll make a few comments and hope that answers the reason for the post.

Explanation:

Zinc(Zn) does react with iron chloride, since zinc is a more reactive metal than the iron.

When Zn is introduced to an iron (III) chloride solution, the Zn disoplaces the Fe atom in a displacement reaction.

The chemical equation of the reaction:

Zn + Fe(III)Cl3 → ZnCl3 + Fe

Energy is often realeased in this type of reaction, since the resulting chemical products have a lower energy that the reactants.

There are several metals more reactive than iron.  One of the more interesting examples of a highly exothermic reaction with iron chloride (rust) is the reaction of aluminum with iron chloride.  `This is highly exothermic and is labelled a thermite reaction.  It provides a spectacular flame that is not enough to weld railroad tracks together.

These values also increase from the bottom to the top of a group because the size of the atom decreases, resulting in a distance
Allushta [10]

<span>These values also increase from the bottom to the top of a group because the size of the atom decreases, resulting in a smaller distance between the nucleus and the valence electron shell, which increases the attraction between the protons and electrons.</span>

Answer:

549.563868

Explanation:

1 mole is equal to 1 moles N2O3, or 76.0116 grams. so 76.0116 x 7.23 = 549.563868

write a short paragraph (3-4 sentences) explaining what makes Metallic bonding. Make sure to include how the electrons interact,
bonufazy [111]

Answer:

Metallic bonding may be described as the sharing of free electrons among a lattice of positively charged metal ions. The structure of metallic bonds is very different from that of covalent and ionic bonds. While ionic bonds join metals to nonmetals, and covalent bonds join nonmetals to nonmetals, metallic bonds are responsible for the bonding between metal atoms.

In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize. That is to say, instead of orbiting their respective metal atoms, they form a “sea” of electrons that surrounds the positively charged atomic nuclei of the interacting metal ions. The electrons then move freely throughout the space between the atomic nuclei.
