Rewriting The Nonsense Reaction Equations Into A Plausible Format:1. $2 \text{KBrO}_3 \rightarrow 2 \text{KBr} + 3 \text{O}_2$2. $2 \text{Al}_2\text{O}_3 \rightarrow 4 \text{Al} + 3 \text{O}_2$3. $2 \text{Na} + 2

Introduction

Chemical reactions are the backbone of chemistry, and understanding them is crucial for any chemistry enthusiast. However, sometimes we come across reaction equations that seem nonsensical or implausible. In this article, we will take a closer look at three such reaction equations and rewrite them into a more plausible format.

Reaction Equation 1: $2 \text{KBrO}_3 \rightarrow 2 \text{KBr} + 3 \text{O}_2$

The first reaction equation is $2 \text{KBrO}_3 \rightarrow 2 \text{KBr} + 3 \text{O}_2$. At first glance, this equation seems to suggest that potassium bromate ($\text{KBrO}_3$) decomposes into potassium bromide ($\text{KBr}$) and oxygen gas ($\text{O}_2$). However, this equation is not balanced, and the stoichiometry is incorrect.

To rewrite this equation, we need to consider the oxidation state of the elements involved. Potassium ($\text{K}$) is a Group 1 element, which means it has an oxidation state of +1. Bromine ($\text{Br}$) is a Group 17 element, which means it has an oxidation state of -1. Oxygen ($\text{O}$) is a Group 16 element, which means it has an oxidation state of -2.

Using this information, we can rewrite the equation as follows:

$$\text{KBrO}_3 \rightarrow \text{KBr} + \frac{3}{2}\text{O}_2$$

However, this equation is still not balanced. To balance the equation, we need to consider the number of atoms of each element on both sides of the equation. The correct balanced equation is:

$$2\text{KBrO}_3 \rightarrow 2\text{KBr} + \frac{5}{2}\text{O}_2$$

Reaction Equation 2: $2 \text{Al}_2\text{O}_3 \rightarrow 4 \text{Al} + 3 \text{O}_2$

The second reaction equation is $2 \text{Al}_2\text{O}_3 \rightarrow 4 \text{Al} + 3 \text{O}_2$. This equation suggests that aluminum oxide ($\text{Al}_2\text{O}_3$) decomposes into aluminum metal ($\text{Al}$) and oxygen gas ($\text{O}_2$). However, this equation is not balanced, and the stoichiometry is incorrect.

To rewrite this equation, we need to consider the oxidation state of the elements involved. Aluminum ($\text{Al}$) is a Group 13 element, which means it has an oxidation state of +3. Oxygen ($\text{O}$) is a Group 16 element, which means it has an oxidation state of -2.

Using this information, we can rewrite the equation as follows:

$$\text{Al}_2\text{O}_3 \rightarrow 2\text{Al} + \frac{3}{2}\text{O}_2$$

However, this equation is still not balanced. To balance the equation, we need to consider the number of atoms of each element on both sides of the equation. The correct balanced equation is:

$$2\text{Al}_2\text{O}_3 \rightarrow 4\text{Al} + 3\text{O}_2$$

Reaction Equation 3: $2 \text{Na} + 2 \text{H}_2\text{O} \rightarrow 2 \text{NaOH} + \text{H}_2$

The third reaction equation is $2 \text{Na} + 2 \text{H}_2\text{O} \rightarrow 2 \text{NaOH} + \text{H}_2$. This equation suggests that sodium metal ($\text{Na}$) reacts with water ($\text{H}_2\text{O}$) to form sodium hydroxide ($\text{NaOH}$) and hydrogen gas ($\text{H}_2$). However, this equation is not balanced, and the stoichiometry is incorrect.

To rewrite this equation, we need to consider the oxidation state of the elements involved. Sodium ($\text{Na}$) is a Group 1 element, which means it has an oxidation state of +1. Hydrogen ($\text{H}$) is a Group 1 element, which means it has an oxidation state of +1. Oxygen ($\text{O}$) is a Group 16 element, which means it has an oxidation state of -2.

Using this information, we can rewrite the equation as follows:

$$2\text{Na} + 2\text{H}_2\text{O} \rightarrow 2\text{NaOH} + \text{H}_2$$

However, this equation is still not balanced. To balance the equation, we need to consider the number of atoms of each element on both sides of the equation. The correct balanced equation is:

$$2\text{Na} + 2\text{H}_2\text{O} \rightarrow 2\text{NaOH} + \text{H}_2$$

Conclusion

In conclusion, rewriting the nonsense reaction equations into a plausible format requires a deep understanding of the oxidation states of the elements involved and the stoichiometry of the reaction. By considering the oxidation states and the number of atoms of each element on both sides of the equation, we can rewrite the equations into a more plausible format.
