Balance the chemical equation
${\text{BaC}}{{\text{l}}_2}{\text{ + }}{{\text{H}}_{\text{2}}}{\text{S}}{{\text{O}}_{\text{4}}} \to {\text{BaS}}{{\text{O}}_{\text{4}}}{\text{ + HCl}}$

Answer 1

Hint : A chemical equation is a symbolically represented chemical reaction in the form of symbols and formulas, with the reactant entities on the left and the product entities on the right. The absolute values of the stoichiometric numbers are represented by the coefficients adjacent to the symbols and formulas of things. In 1615, Jean Beguin drew the first diagram of a chemical equation.

Complete Step By Step Answer:
Reactants are the chemicals that undergo reaction, and their formulae are found on the left side of the equation.
The products of the reaction are referred to as products, and their formulae are written on the right side of the equation.
Individual reactant and product formulae are separated by plus signs, and the reactant and product (left and right) sides of the equation are separated by an arrow. Coefficients reflect the relative numbers of reactant and product species (numbers placed immediately to the left of each formula). In most cases, a coefficient of one is ignored.
On the reactant and product sides of a balanced chemical equation, there are equal quantities of atoms for each element involved in the reaction. This is a condition that the equation must meet in order to be compatible with the conservation of matter rule. It may be verified by adding the numbers of atoms on both sides of the arrow and comparing them to check that they are equal. Note that the number of atoms in any formula involving that element is computed by multiplying the coefficient by the element's subscript in the expression.
Hence in ${\text{BaC}}{{\text{l}}_2}{\text{ + }}{{\text{H}}_{\text{2}}}{\text{S}}{{\text{O}}_{\text{4}}} \to {\text{BaS}}{{\text{O}}_{\text{4}}}{\text{ + HCl}}$ only HCl needs to be modified,
Hence it becomes ${\text{BaC}}{{\text{l}}_2}{\text{ + }}{{\text{H}}_{\text{2}}}{\text{S}}{{\text{O}}_{\text{4}}} \to {\text{BaS}}{{\text{O}}_{\text{4}}}{\text{ + 2HCl}}$

Note :
When balancing a chemical equation, it's occasionally easier to utilise fractions instead of integers as intermediate coefficients. Once the equation is balanced, all of the coefficients may be multiplied by a whole number to convert fractional coefficients to integers without disturbing the atom balance.
