1. In the given in this item, we may solve directly the molar masses of the reactants and the products to see if they are matching.
Reactant: (2N2) = (2)(28.0 g/mol) = 56 g
(3O2) = (3)(32.0 g/mol) = 96 g
total = 152 g
Product: (2N2O3) = (2)(76 g/mol) = 152 g
The reactant and product have the same masses.
2. From the given balanced chemical equation, we use the stoichiometric ratio,
(14 moles of FECl3)(3 moles Cl2/2 moles of FeCl3)
= 21 moles of Cl2

The study of chemicals and bonds is called chemistry. When two elements are joined together to form a single compound is called a combination reaction.
The correct answer to the question is described as follows:-
What is a mole?
- The mole is the base unit of the amount of substance in the International System of Units (SI).
- It is defined as exactly[tex]6.02214076*10^{23[/tex] elementary entities which may be atoms, molecules, ions, or electrons.
In the given in this item, we may solve directly the molar masses of the reactants and the products to see if they are matching.
Reactant:
- [tex](2N_2) = (2)*(28.0) = 56 g[/tex]
- [tex](3O_2) = (3)*(32.0) = 96 g[/tex]
The total mass is 152 g
Product:
- [tex](2N_2O_3) = (2)*(76) = 152 g[/tex]
Hence, The reactant and product have the same masses.
The answer to the second question is as follows:-
From the given balanced chemical equation, we use the stoichiometric ratio,
[tex](14 )*\frac{3}{2}[/tex] = 21 moles of Cl2
Hence, the correct answer is 21 moles.
