Complete and balance the following reactions: Ag + HNO 3 ( dilute ) → _____+_____+_____.

When nitric acid reacts with silver, silver nitrate is formed along with water and oxides of nitrogen. Silver metal reacts with cold dilute nitric acid and produce silver nitrate ( AgNO 3 ) salt, nitric oxide ( NO ) gas and water as products. This reaction is a redox reaction (oxidation - reduction reaction) too. The balanced chemical reaction is given below, 3 Ag + 4 HNO 3 ( dilute ) → 3 AgNO 3 + NO + 2 H 2 O .

Write a balanced chemical equation for the following: Reaction of excess ammonia with chlorine.

Ammonia is a reducing agent which adds hydrogen to the other reactant in a reaction. A reaction between chlorine and excess of ammonia results in the formation of ammonium chloride and nitrogen gas. The balanced chemical reaction is as follows: 8 NH 3 excess + 3 Cl 2 → 6 NH 4 Cl + N 2 ↑
