Answer:
NCl₃ + 2 H₂O = HNO₂ + 3 HCl
Explanation:
Let's consider the unbalanced equation showing the reaction between nitrogen trichloride and water to form nitrous acid and hydrochloric acid.
NCl₃ + H₂O = HNO₂ + HCl
We start balancing Cl atoms by multiplying HCl by 3.
NCl₃ + H₂O = HNO₂ + 3 HCl
Then, we balance O atoms by multiplying H₂O by 2.
The equation is now balanced.
