Oct 13, 2025 by wbrum.org 103 views

Introduction

Potassium is a highly reactive metal that readily reacts with oxygen to form a compound known as potassium oxide. This reaction is a fundamental concept in chemistry, and understanding the balanced chemical equation is crucial for predicting the products of chemical reactions. In this article, we will explore the correct balanced chemical reaction between potassium and oxygen.

The Reactants

Potassium (K) is a highly reactive metal that belongs to the alkali metal group. It is highly electropositive, meaning it readily loses one electron to form a positive ion. Oxygen (O2) is a highly reactive gas that readily accepts two electrons to form a negative ion.

The Products

The product of the reaction between potassium and oxygen is potassium oxide (K2O). This compound is a white solid that is highly reactive and readily decomposes into its constituent elements.

The Balanced Chemical Reaction

The balanced chemical reaction between potassium and oxygen is a critical concept in chemistry. The correct balanced chemical reaction is:

2K + O2 → 2K2O

This equation indicates that two moles of potassium react with one mole of oxygen to form two moles of potassium oxide.

Explanation

The balanced chemical reaction can be explained as follows:

Two moles of potassium (2K) react with one mole of oxygen (O2) to form two moles of potassium oxide (2K2O).
The reaction involves the transfer of electrons from the potassium atoms to the oxygen molecule, resulting in the formation of potassium ions and oxygen ions.
The potassium ions combine with the oxygen ions to form potassium oxide (K2O).

Comparison with Other Options

The other options provided are incorrect because they do not accurately represent the balanced chemical reaction between potassium and oxygen.

Option A: K + O2 → K2O is incorrect because it does not account for the fact that two moles of potassium react with one mole of oxygen.
Option B: K2 + O2 → K2O2 is incorrect because it does not accurately represent the products of the reaction.
Option D: is not provided.

Conclusion

In conclusion, the correct balanced chemical reaction between potassium and oxygen is 2K + O2 → 2K2O. This equation accurately represents the products of the reaction and is a fundamental concept in chemistry.

Additional Information

Potassium oxide (K2O) is a highly reactive compound that readily decomposes into its constituent elements.
The reaction between potassium and oxygen is highly exothermic, releasing a significant amount of heat energy.
The balanced chemical reaction is a critical concept in chemistry, and understanding it is essential for predicting the products of chemical reactions.
