Conversion of Reaction Schemes to Chemical Equations

Here are the chemical equations for the given reaction schemes:

A. H2O → O2 + H2 B. 2KNO3 → 2KNO2 + O2 C. 2CO + O2 → 2CO2 D. 4P + 5O2 → 2P2O5

Let's break down each reaction and identify the type of reaction involved.

Reaction A: H2O → O2 + H2

This reaction represents the decomposition of water into oxygen and hydrogen gas. It can be classified as a decomposition reaction.

Reaction B: 2KNO3 → 2KNO2 + O2

This reaction shows the decomposition of potassium nitrate into potassium nitrite and oxygen gas. It is also a decomposition reaction.

Reaction C: 2CO + O2 → 2CO2

This equation represents the combination of carbon monoxide and oxygen gas to form carbon dioxide. It is a combination reaction.

Reaction D: 4P + 5O2 → 2P2O5

This reaction demonstrates the combination of phosphorus and oxygen gas to produce diphosphorus pentoxide. It is also a combination reaction.

Please note that the above chemical equations are balanced and represent the conversion of the given reaction schemes into chemical equations.
