Which of the following chemical equations is not balanced ? A) NH4NO3  N2O + 2H2O B) C12H22O11  12C + 11H2O C) 2NH4SCN + Ba(OH)2 • 8H2O  2NH3 + 10H2O + Ba(SCN)2 D) (NH4)2Cr2O7  N2O + Cr2O3 + 4H2O E) 2Mg + CO2  2MgO + C

Respuesta :

Answer:

D) (NH₄)₂Cr₂O₇(s) = N₂O + Cr₂O₃ + 4 H₂O

Explanation:

The correct Balanced equation

(NH₄)₂Cr₂O₇(s) = N₂(g) + Cr₂O₃(s) + 4 H₂O(g)

This equation occurs when ammonium dichromate undergoes decomposition to produce water, chromium (III)oxide crystal and Nitrogen gas.

Other balanced equation are correct.

The individual number of atoms in both side as same.
