Answer 1

The question pertains to a chemical reaction involving MgO and LiCl to form MgCl₂ and Li₂O, demonstrating electron transfer and changes in oxidation states in the formation of ionic compounds like magnesium chloride.

Step-by-step explanation:

The question concerns a chemical reaction where magnesium oxide (MgO) reacts with lithium chloride (LiCl) to form magnesium chloride (MgCl₂) and lithium oxide (Li₂O). This type of reaction involves the transfer of electrons, leading to changes in oxidation states of the elements involved. In the provided reactions, Mg acts as the reducing agent while Cl acts as the oxidizer. The correctly balanced chemical equation is MgO + 2 LiCl → MgCl₂ + Li₂O. The equations provided demonstrate several variations of reactions with magnesium compounds, highlighting the reactivity of magnesium with other substances and its ability to form various compounds such as magnesium chloride.

Concerning the provided reaction Mg(s) + Cl₂(g) → MgCl₂(s), magnesium (Mg) is oxidized as it goes from an oxidation state of 0 to +2, and chlorine (Cl₂) is reduced as each chlorine atom goes from an oxidation state of 0 to -1 when forming Cl⁻ ions in magnesium chloride. This reaction exemplifies the concept that during the formation of an ionic compound, electrons are transferred from the metal (Mg) to the nonmetal (Cl). As the Mg loses two electrons, it becomes a Mg²⁵ ion, and as each Cl atom gains one electron, two Cl⁻ ions are formed.
