Answer 2

Li2O2 - LIOH - LiNO3

The given sequence Li2O2 - LIOH - LiNO3 represents a series of chemical reactions involving lithium and oxygen compounds. Let's break down each step in the sequence:

1. Li2O2 (lithium peroxide): - Lithium peroxide (Li2O2) is a compound composed of lithium (Li) and oxygen (O). - It is a yellowish solid that can be formed by the reaction of lithium metal with oxygen gas. - The chemical formula indicates that each molecule of lithium peroxide contains two lithium atoms and two oxygen atoms. - Lithium peroxide can react with water to form lithium hydroxide (LiOH) and release oxygen gas.

2. LIOH (lithium hydroxide): - Lithium hydroxide (LiOH) is a compound composed of lithium (Li) and hydroxide (OH) ions. - It is an inorganic base that is commonly used in various applications, including as a component in alkaline batteries. - Lithium hydroxide can be formed by the reaction of lithium peroxide with water: ``` Li2O2 + 2H2O -> 2LiOH + H2O2 ``` - In this reaction, lithium peroxide reacts with water to produce lithium hydroxide and hydrogen peroxide (H2O2).

3. LiNO3 (lithium nitrate): - Lithium nitrate (LiNO3) is a compound composed of lithium (Li) and nitrate (NO3) ions. - It is a white crystalline solid that is commonly used in the production of fireworks and pyrotechnics. - Lithium nitrate can be formed by the reaction of lithium hydroxide with nitric acid (HNO3): ``` LiOH + HNO3 -> LiNO3 + H2O ``` - In this reaction, lithium hydroxide reacts with nitric acid to produce lithium nitrate and water.

In summary, the given sequence Li2O2 - LIOH - LiNO3 represents a series of chemical reactions where lithium peroxide (Li2O2) reacts with water to form lithium hydroxide (LiOH) and oxygen gas. Then, lithium hydroxide reacts with nitric acid (HNO3) to produce lithium nitrate (LiNO3) and water.
