Introduction

Balancing chemical equations is a crucial concept in chemistry that helps us understand the stoichiometry of chemical reactions. It is essential to balance chemical equations to ensure that the law of conservation of mass is obeyed. In this article, we will focus on balancing the oxidation of aluminum equation, which is a fundamental concept in chemistry.

Understanding the Oxidation of Aluminum Equation

The oxidation of aluminum is a chemical reaction that involves the reaction of aluminum with oxygen to form aluminum oxide. The unbalanced equation for this reaction is:

${ Al + O_2 \rightarrow Al_2O_3 }$

To balance this equation, we need to determine the correct sequence of coefficients that should be placed in the blanks.

Step 1: Count the Number of Atoms

The first step in balancing a chemical equation is to count the number of atoms of each element on both the reactant and product sides. Let's count the number of atoms of each element in the given equation:

Aluminum (Al): 1 atom on the reactant side and 2 atoms on the product side
Oxygen (O): 2 atoms on the reactant side and 3 atoms on the product side

Step 2: Balance the Aluminum Atoms

To balance the aluminum atoms, we need to place a coefficient in front of the aluminum atom on the reactant side. Since there are 2 aluminum atoms on the product side, we need to place a coefficient of 2 in front of the aluminum atom on the reactant side.

${ 2Al + O_2 \rightarrow Al_2O_3 }$

Step 3: Balance the Oxygen Atoms

Next, we need to balance the oxygen atoms. Since there are 3 oxygen atoms on the product side, we need to place a coefficient of 3/2 in front of the oxygen molecule on the reactant side. However, we cannot have a fraction as a coefficient, so we need to multiply both sides of the equation by 2 to eliminate the fraction.

${ 2Al + 3O_2 \rightarrow 2Al_2O_3 }$

Step 4: Check the Balance

Now that we have placed the coefficients in front of the aluminum and oxygen atoms, we need to check if the equation is balanced. Let's count the number of atoms of each element on both the reactant and product sides:

Aluminum (Al): 2 atoms on the reactant side and 4 atoms on the product side
Oxygen (O): 6 atoms on the reactant side and 6 atoms on the product side

The equation is now balanced, and we have determined the correct sequence of coefficients that should be placed in the blanks.

Conclusion

In conclusion, the correct sequence of coefficients that should be placed in the blanks to balance the oxidation of aluminum equation is:

${ 2Al + 3O_2 \rightarrow 2Al_2O_3 }$

This equation is balanced, and the law of conservation of mass is obeyed.

Answer

The correct answer is:

A. 2, 3, 1
