NH4NO3(s)—> N2O(g) +H2O(g)

Hey there!

Assuming you want the equation balanced:

NH₄NO₃ → N₂O + H₂O

Balance N.

2 on the left, 2 on the right. Already balanced.

Balance H.

4 on the left, 2 on the right. Add a coefficient of 2 in front of H₂O.

NH₄NO₃ → N₂O + 2H₂O

Balance O.

3 on the left, 3 on the right. Already balanced.

Your final balanced equation:

NH₄NO₃ → N₂O + 2H₂O

Hope this helps!

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
