<u>Balanced chemical reaction:
</u>
The chemical reaction that contains equal number of atoms of the different elements in the reactant as well as in the product side is known as balanced chemical reaction. The chemical equation is required to be balanced to follow the Law of the conservation of mass.
Stoichiometry of a reaction is used to determine the amount of species present in the reaction by the relationship between the reactants and products. It can be used to determine the moles of a chemical species when the moles of other chemical species present in the reaction is given.
Consider the general reaction,
Here,
A and B are reactants.
C is the product.
One mole of A reacts with two moles of B to produce three moles of C. Stoichiometric ratio between A and B is 1:2, the stoichiometric ratio between A and C is 1:3, and the stoichiometric ratio between B and C is 2:3.
The balanced chemical reaction between
and
is as follows:
![{\text{Ca}}{{\text{F}}_2}+{{\text{H}}_2}{\text{S}}{{\text{O}}_4}\to{\text{CaS}}{{\text{O}}_4}+{{\text{H}}_2}+{{\text{F}}_2}](https://tex.z-dn.net/?f=%7B%5Ctext%7BCa%7D%7D%7B%7B%5Ctext%7BF%7D%7D_2%7D%2B%7B%7B%5Ctext%7BH%7D%7D_2%7D%7B%5Ctext%7BS%7D%7D%7B%7B%5Ctext%7BO%7D%7D_4%7D%5Cto%7B%5Ctext%7BCaS%7D%7D%7B%7B%5Ctext%7BO%7D%7D_4%7D%2B%7B%7B%5Ctext%7BH%7D%7D_2%7D%2B%7B%7B%5Ctext%7BF%7D%7D_2%7D)
According to stoichiometry of the reaction, 1 mole of
is produced by 1 mole of
.
Given number of moles of
is 1.12 moles.
Therefore, number of moles of
will be equal to number of moles of
and that is 1.12 moles.
Molar mass of
is 78.07 g/mol.
The formula to calculate mass of
is as follows:
…… (1)
Substitute 1.12 mol for number of moles and 78.07 g/mol for molar mass of
in equation (1).
![\begin{aligned}{\text{Mass}}\left({\text{g}}\right)&=\left({{\text{1}}{\text{.12 mol}}}\right)\left({{\text{78}}{\text{.07 g/mol}}}\right)\\&={\text{87}}{\text{.4384 g}}\\\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7D%7B%5Ctext%7BMass%7D%7D%5Cleft%28%7B%5Ctext%7Bg%7D%7D%5Cright%29%26%3D%5Cleft%28%7B%7B%5Ctext%7B1%7D%7D%7B%5Ctext%7B.12%20mol%7D%7D%7D%5Cright%29%5Cleft%28%7B%7B%5Ctext%7B78%7D%7D%7B%5Ctext%7B.07%20g%2Fmol%7D%7D%7D%5Cright%29%5C%5C%26%3D%7B%5Ctext%7B87%7D%7D%7B%5Ctext%7B.4384%20g%7D%7D%5C%5C%5Cend%7Baligned%7D)
Hence, the amount of
is 87.4384 g.
