Balance the chemical equation. (Blank) N2O3 → (Blank) N2 + (Black) O2
Anna71 [15]

  The balanced equation is as below

 2 N₂O₃ →  2N₂ + 3O₂

<u><em> Explanation</em></u>

According  to the law  of mass conservation the  number of atoms  in reactants side must  be equal  the to the number of atoms in products  side.

 Therefore the  balanced reaction  above is balanced  since the number of atoms  in reactants side  are equal to number of atoms in products side.

For  there 4 atoms  of N   in reactants  side and  4 in products side.

Process

1.- The sign of the number after the name indicates if the element has lost or gained electrons.

If the sign is positive the element has lost electrons

If the sign is negative the element has gained electrons.

2.- Phosphorus atomic number is 15, then the number of electrons in Phosphorus 3+ will be 12, in this example, Phosphorus lost 3 electrons.
