Answer:
3 NO₂ (g) + H₂O (l) ---> 2 HNO₃ (aq) + NO (g)
Explanation:
Gaseous nitrogen dioxide = NO₂ (g)
Liquid water = H₂O (l)
Because the reactants are dissolved = HNO₃ (aq)
Gaseous nitrogen monoxide = NO (g)
In order for a reaction to be balanced, there needs to be an equal amount of each type of atom on both sides of the equation. The equation can be balanced by adding coefficients to modify the quantities of certain compounds.
The unbalanced equation:
NO₂ (g) + H₂O (l) ---> HNO₃ (aq) + NO (g)
<u>Reactants</u>: 1 nitrogen, 3 oxygen, 2 hydrogen
<u>Products</u>: 2 nitrogen, 4 oxygen, 1 hydrogen
The balanced equation:
3 NO₂ (g) + H₂O (l) ---> 2 HNO₃ (aq) + NO (g)
<u>Reactants</u>: 3 nitrogen, 7 oxygen, 2 hydrogen
<u>Products</u>: 3 nitrogen, 7 oxygen, 2 hydrogen
