Introduction
In chemistry, mole ratio is a crucial concept that helps us understand the relationship between the amounts of different substances involved in a chemical reaction. In this article, we will explore the mole ratio of oxygen to aluminum in a specific reaction.
The Reaction
The reaction given is:
This reaction involves the decomposition of aluminum oxide (Al2O3) into aluminum (Al) and oxygen (O2). To determine the mole ratio of oxygen to aluminum, we need to analyze the coefficients of the reactants and products in the balanced equation.
Balancing the Equation
The given equation is already balanced, meaning that the number of atoms of each element is the same on both the reactant and product sides. However, to make it easier to understand the mole ratio, let's rewrite the equation with the coefficients:
Determining the Mole Ratio
To determine the mole ratio of oxygen to aluminum, we need to compare the number of moles of each substance involved in the reaction. The mole ratio is calculated by dividing the number of moles of one substance by the number of moles of another substance.
In this reaction, we have 3 moles of O2 and 4 moles of Al. To find the mole ratio of oxygen to aluminum, we can divide the number of moles of oxygen by the number of moles of aluminum:
Simplifying the Mole Ratio
The mole ratio can be simplified by dividing both numbers by their greatest common divisor (GCD). In this case, the GCD of 3 and 4 is 1, so the mole ratio remains the same:
Conclusion
In conclusion, the mole ratio of oxygen to aluminum in the given reaction is 3:4. This means that for every 3 moles of oxygen produced, 4 moles of aluminum are also produced. Understanding the mole ratio is essential in chemistry, as it helps us predict the amounts of substances involved in a reaction and calculate the yields of products.
