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:
Heat transfer is related to temperature change.
Explanation:
Answer:
A
Explanation:
For the water cycle to work, water has to get from the Earth's surface back up into the skies so it can rain back down and ruin your parade or water your crops or yard. It is the invisible process of evaporation that changes liquid and frozen water into water-vapor gas, which then floats up into the skies to become clouds.
valence electrons are the number of electrons in the outermost shell.
electron configuration is where the electrons are arranged in ascending order of energy shells
the electron configurations for the elements given are as follows
C - 2,4
Al - 2,8,3
Na - 2,8,1
Ca - 2,8,8,2
from the given elements, Aluminium has 3 electrons in its outermost shell.
answer is Aluminium
