The element that has been reduced in the chemical equation is
.
The given reaction has been:
![\rm Mg\;+\;Cl_2\;\rightarrow\;Mg^2^+\;+\;2\;Cl^-](https://tex.z-dn.net/?f=%5Crm%20Mg%5C%3B%2B%5C%3BCl_2%5C%3B%5Crightarrow%5C%3BMg%5E2%5E%2B%5C%3B%2B%5C%3B2%5C%3BCl%5E-)
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
.

Answer:
D) single replacement
Explanation:
Given reaction:
Mg + 2HCl → MgCl₂ + H₂
The reaction shown above is a single displacement reaction.
In a single displacement reaction, a more reactive atom displaces another from a given compound.
The comparison here is between Mg and H.
On the activity series, Mg is higher and more reactive, it will displace H from the solution of HCl. This
This reaction type is called a single replacement reaction.

I believe the correct answers from the choices listed above are the second and the last option. At constant pressure, the systems 2A(g) + B(g) ---> 4C(g) and 2C(g) A(s) + B(s) ---> C(g) produces work to the surroundings. <span>When a gas is evolved during a chemical reaction, the gas can be imagined as displacing the atmosphere - pushing it back against the atmospheric pressure. The work done is therefore V*P where V is the volume of gas evolved, and P is the atmospheric pressure. </span>
