This reaction involves the combination of aluminum (Al) and oxygen gas (O2) to form aluminum oxide (Al2O3). The reaction is a classic example of a synthesis reaction, where two or more substances combine to form a new compound.
Stoichiometry of the Reaction
Stoichiometry is the branch of chemistry that deals with the quantitative relationships between reactants and products in chemical reactions. In the given reaction, the stoichiometry can be represented by the coefficients in the balanced chemical equation.
The balanced chemical equation is:
4Al + 3O2 β 2Al2O3
From the equation, we can see that 4 moles of aluminum (Al) react with 3 moles of oxygen gas (O2) to produce 2 moles of aluminum oxide (Al2O3).
Calculating the Ratio
To calculate the ratio between Al and O2, we need to determine the number of moles of each substance involved in the reaction. The ratio can be calculated by dividing the number of moles of one substance by the number of moles of the other substance.
Let's calculate the ratio:
Number of moles of Al = 4 Number of moles of O2 = 3
Ratio of Al to O2 = Number of moles of Al / Number of moles of O2 = 4 / 3 = 1.33 (approximately)
Interpretation of the Ratio
The ratio of Al to O2 is 1.33:1, which means that for every 1 mole of O2, 1.33 moles of Al are required to react with it. This ratio is a fundamental aspect of the chemical reaction and is essential for predicting the amounts of reactants and products involved.
Importance of Stoichiometry
Stoichiometry plays a crucial role in chemistry, as it allows us to predict the amounts of reactants and products involved in a chemical reaction. This knowledge is essential for designing and optimizing chemical reactions, as well as for scaling up reactions to industrial levels.
Conclusion
In conclusion, the ratio between Al and O2 in the chemical reaction 4Al + 3O2 β 2Al2O3 is 1.33:1. This ratio is a fundamental aspect of the reaction and is essential for predicting the amounts of reactants and products involved.
