The correctly balanced equation of the reaction would be [tex]Na + Mn_2O_3 - > NaO_3 + Mn_2[/tex]. Option 1.
A balanced equation of a chemical reaction is an equation that conserves the number of different atoms in the reactants and products in accordance with the law of conservation of atoms.
According to the law of conservation of atoms, the number of different atoms in the reactants and products of chemical reactions must be the same, even though their forms might change.
Going by this law, a balanced equation will have the same number of atoms of different elements in the reactants and in the products. The only equation that fulfills this condition is:
[tex]Na + Mn_2O_3 - > NaO_3 + Mn_2[/tex]
Others do not have balanced atoms in the reactants and the products.
