Question

What are the reactants and products in the following reaction:
$MgC{l_2} + L{i_2}C{O_3} \to MgC{O_3} + 2LiCl$

Answer 1

Chemical equation is the representation of a chemical process in the form of symbols (substances). Reactants, products, and an arrow indicating the reaction's direction make up a chemical equation. A balanced chemical equation is one in which the number of atoms in all molecules is equal on both sides of the equation.

Complete answer:
$MgC{l_2} + L{i_2}C{O_3} \to MgC{O_3} + 2LiCl$
In the above reaction, Magnesium chloride ( $MgC{l_2}$ ) and Lithium carbonate ( $L{i_2}C{O_3}$ ) are the reactants. Magnesium carbonate ( $MgC{O_3}$ ) and Lithium chloride ( $2LiCl$ ) are the products.
The above reaction is a double displacement reaction.
Double displacement reactions are those in which two chemicals react by exchanging ions to produce two new molecules. Positive ions exchange negative ion partners in double replacement processes. Ionic chemicals dissolved in water undergo double displacement processes. The general equation given below represents a double replacement reaction.
$AB + CD \to AD + CB$

Additional Information:
Double displacement reactions can be further classified as neutralization and precipitation reactions.
Neutralization reaction: The acid-base process produces salt (which is naturally neutral) and water.
Precipitation reaction: The precipitate is formed in a solution or inside another solid during a chemical reaction in this reaction.

Note:
The law of conservation of mass governs the balancing of a chemical equation. This law states that in a chemical reaction, mass cannot be generated or destroyed, and that the total mass of the elements or molecules present on the reactant side should match the total mass of elements or molecules present on the product side.
