Answer:

Calcium carbonate is another example of a compound with both ionic and covalent bonds.

Explanation:

In chemistry, an ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. The compound is neutral overall, but consists of positively charged ions called cations and negatively charged ions called anions.

Given the reaction below, which is the being reduced? Mg Cl2 Right arrow. Mg2 2Cl– 2CI– CI2 Mg Mg2.
Jlenok [28]

The element that has been reduced in the chemical equation is \rm Cl_2.

The given reaction has been:

\rm Mg\;+\;Cl_2\;\rightarrow\;Mg^2^+\;+\;2\;Cl^-

The reaction has been the redox reaction, in which the one of the reactant has been oxidized, and the other has been reduced in the chemical reaction.

<h3>Reduction in the reaction</h3>

The reduction has been defined as the gain of electrons. In the given reaction, the Mg loses 2 electrons and has been converted to the Mg ion.

Thus, Mg has been oxidized in the reaction.

The Cl has been present as the diatomic molecule and with the gain of two electrons from the Mg it has been converted to two chloride ions.

Thus, the element that has been reduced in the chemical equation is \rm Cl_2.

What is the overall charge of the compound frfr
matrenka [14]

Answer:

As any molecular or ionic compound, 0 net charge, as a hypothetical diatomic cation, 2+

Explanation:

The question states that this is a compound, and any molecular or ionic compound would have a net charge of 0.

However, such a compound doesn't exist. Francium generally exists in nature having a 1+ charge in its cation form. Combining two francium ions would result in a Fr_2^{2+} species which is simply a diatomic ion but not a compound.
