The decomposition of 128.4 g ammonium nitrate yields how many liters of water at
1.89 atm and 314 K?
(N = 14.01 g/mol, H = 1.008 g/mol, O = 16.00 g/mol)
NH4NO3(s) → N2O(g) + 2H2O(g)
Hint: R = 0.0821 L atm/(mol K)

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."
