Answer:
       18 g of H₂O
Solution:
The Balance Chemical Reaction is as follow,
               2 NH₄NO₃   →   2 N₂  +  O₂  +  4 H₂O
According to Equation ,
       160 g (2 mole) NH₄NO₃ produces  =  72 g (4 moles) of H₂O
So,
            40 g of NH₄NO₃ will produce  =  X g of H₂O
Solving for X,
           X =  (40 g × 72 g) ÷ 160 g
           X  =  18 g of H₂O
When 40 g of ammonium nitrate explode, 14 g of nitrogen, 8 g of oxygen and 18 g of water are formed.
Let's consider the balanced equation for the decomposition reaction of ammonium nitrate.
2 NH₄NO₃ → 2 N₂ + O₂ + 4 H₂O
According to Lavoisier's law of conservation of mass, the sum of the masses of the reactants must be equal to the sum of the masses of the products over a chemical reaction. The mass of water formed is:
[tex]mNH_4NO_3 = mN_2 + mO_2 + mH_2O\\mH_2O = mNH_4NO_3 - mN_2 - mO_2\\mH_2O = 40 g - 14 g - 8 g = 18 g[/tex]
When 40 g of ammonium nitrate explode, 14 g of nitrogen, 8 g of oxygen and 18 g of water are formed.
