When ammonium nitrate (nh4no3) explodes, the products are nitrogen, oxygen and water. when 40 grams of ammonium nitrate explode, 14 grams of nitrogen and 8 grams of oxygen form. how many grams of water form?

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

Answer;

18 g of water

Explanation;

H4NO3 - --> N2 + O2 + H2O

... 40 g ... 14 g ... 8 g:

mass NH4NO3 = mass N2 + mass O2 + mass H2O

40 g = 14 g + 8g + mass H2O

Solving for mass H2O:

mass H2O = 40 g - 14 g - 8g = 18 g H2O

=18 g of water
