Question

Balancing Chemical Equations

Write and balance the equation showing the reaction between nitrogen trichloride and water to form nitrous acid and hydrochloric acid.

Answer 1

NCl₃ + 2 H₂O = HNO₂ + 3 HCl

Step-by-step 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.

NCl₃ + 2 H₂O = HNO₂ + 3 HCl

The equation is now balanced.
