Chemical equations are a fundamental concept in chemistry, representing the transformation of one or more substances into another. However, not all chemical equations are balanced, meaning that the number of atoms of each element on the reactant side does not equal the number of atoms of each element on the product side. In this article, we will explore the concept of balancing chemical equations, focusing on the oxidation of butene as a case study.
What is a Balanced Chemical Equation?
A balanced chemical equation is a chemical equation in which the number of atoms of each element on the reactant side equals the number of atoms of each element on the product side. This is a crucial concept in chemistry, as it allows us to understand the stoichiometry of a reaction, which is the quantitative relationship between the reactants and products.
The Oxidation of Butene: An Unbalanced Equation
The oxidation of butene is a chemical reaction in which butene reacts with oxygen to produce carbon dioxide and water. The unbalanced equation for this reaction is:
Balancing the Equation
To balance this equation, we need to ensure that the number of atoms of each element on the reactant side equals the number of atoms of each element on the product side. Let's start by counting the number of atoms of each element on both sides of the equation.
On the reactant side, we have:
- 4 carbon atoms (C)
- 8 hydrogen atoms (H)
- 6 oxygen atoms (O)
On the product side, we have:
- 1 carbon atom (C)
- 2 hydrogen atoms (H)
- 2 oxygen atoms (O)
To balance the equation, we need to add coefficients in front of the formulas of the reactants and products. The coefficients are numbers that multiply the formulas of the reactants and products. We can start by adding a coefficient of 4 in front of the formula of carbon dioxide (CO2) to balance the number of carbon atoms.
However, this is not yet balanced, as we still have 8 hydrogen atoms on the reactant side and only 2 hydrogen atoms on the product side. To balance the number of hydrogen atoms, we need to add a coefficient of 4 in front of the formula of water (H2O).
Now, let's count the number of atoms of each element on both sides of the equation again.
On the reactant side, we have:
- 4 carbon atoms (C)
- 8 hydrogen atoms (H)
- 6 oxygen atoms (O)
On the product side, we have:
- 4 carbon atoms (C)
- 8 hydrogen atoms (H)
- 8 oxygen atoms (O)
The equation is now balanced, as the number of atoms of each element on the reactant side equals the number of atoms of each element on the product side.
Conclusion
Balancing chemical equations is a crucial concept in chemistry, as it allows us to understand the stoichiometry of a reaction. In this article, we explored the concept of balancing chemical equations, focusing on the oxidation of butene as a case study. We saw how to balance the equation by adding coefficients in front of the formulas of the reactants and products. By balancing the equation, we can determine the number of molecules of carbon dioxide and water produced for each molecule of butene that reacts.
How Many Molecules of Carbon Dioxide and Water are Produced?
Now that we have balanced the equation, we can determine the number of molecules of carbon dioxide and water produced for each molecule of butene that reacts. According to the balanced equation, 4 molecules of carbon dioxide (CO2) and 4 molecules of water (H2O) are produced for each molecule of butene (C4H8) that reacts.
Answer
The correct answer is: Four carbon dioxide and four water molecules are produced for each molecule of butene that reacts.
