Question

What would occur in the reaction between zinc sulfate and barium chloride $?$

Answer 1

First we have to know that the mass of the products must equal the mass of the reactants in a chemical reaction (according to the law of conservation of mass). To the products of a given reaction. We need to identify what type of reaction occurs. After that we need to balance the chemical reaction, by considering the unbalanced equation. Then name the products.

Complete answer:
Representation of a chemical reaction in terms of symbols and chemical formula of the reactants and products taking part in the reaction is known as a chemical equation. Combination, Decomposition, Single-replacement, Double-replacement, and Combustion are the five basic types of chemical reactions.

A double displacement reaction is a type of chemical reaction in which the reactant ions exchange places to form new products. During this reaction, the cations and anions of two different compounds switch places, forming two entirely different compounds. A double-replacement reaction occurs between two ionic compounds.

Since zinc sulphate and barium chloride are ionic compounds. So, the reaction that occurs between those two compounds is a double displacement reaction. Where, Barium Chloride solution reacts with Zinc sulphate solution to give zinc chloride solution and barium sulphate precipitate.
Its chemical reaction is written as follows
$BaC{l_2}(aq) + ZnS{O_4}(aq) \to ZnC{l_2}(aq) + BaS{O_4}(aq)$ ----(1)
In the equation (1), the number of atoms in the reactants and products are equal.
Hence, the balanced chemical equation is
$BaC{l_2}(aq) + ZnS{O_4}(aq) \to ZnC{l_2}(aq) + BaS{O_4}(aq)$
Hence the products are zinc chloride solution and Barium sulphate.

Note:
To balance the chemical reaction, consider the unbalanced reaction. Then Identify and count the atoms in both the reactants and products in the following reaction. Then to make the number of atoms the same on both the reactants and products sides, we need to add coefficients (the numbers in front of the formulas) so that the number of atoms of each element is the same on both sides of the chemical equation. Also note that in a double displacement reaction, the chemical bonds between the reactants may be either covalent or ionic.
