Question

Give balanced chemical equations to prepare the following salt:
Copper chloride using copper carbonate

Answer 1

Hint: To solve this question, we must first understand the basic rules for balancing a chemical equation. Then we need to identify the other reactants and products that would be involved in this reaction. On the basis of all this data, we can get the final reaction.

Complete step by step answer:
Before we move forward with the solution of the given question, let us first understand some important basic concepts. To balance a chemical reaction, we need to follow the following steps:
1.Identify the reactants and the products
2.Write the chemical equation without any coefficients for any chemicals
3.Then identify the number of atoms of a particular element in the reactants. Try to equate the number of atoms of that element in both the reactants and the products by adding certain coefficients for the corresponding compounds on both the sides.
4.Continue this process till all the elements are balanced and that the number of atoms on the reactant side of the equation is equal to the number of atoms on the product side of the equation.
Now, let us move towards the question given to us. We are asked to give the balanced chemical reaction for the formation of copper chloride using copper carbonate. The reactants used in this reaction are copper carbonate and hydrochloric acid. These two compounds react to form copper chloride. This reaction also results in the formation of water and carbon dioxide as by-products. The chemical equation for the same can be given as:
 \[CuC{O_3} + HCl \to CuC{l_2} + {H_2}O + C{O_2}\]
Balancing the number of atoms of each element on both the sides, we get:
 \[CuC{O_3} + 2HCl \to CuC{l_2} + {H_2}O + C{O_2}\]
This is the balanced chemical reaction for the formation of copper chloride using copper carbonate.

Note: Because the identities of the reactants and products are fixed, the equation cannot be balanced by changing the subscripts of the reactants or the products. To do so would change the chemical identity of the species being described.
