What will the balance read after the chemical is ignited and completely burned?

Understanding the Basics of Chemical Reactions

When a chemical is ignited and completely burned, it undergoes a process known as combustion. Combustion is a chemical reaction between a fuel source and an oxidizing agent, typically oxygen, that releases energy in the form of heat and light. This process involves the breaking and forming of chemical bonds, resulting in the formation of new substances.

The Law of Conservation of Mass

A fundamental principle in chemistry is the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction. This means that the total mass of the reactants (the substances involved in the reaction) is equal to the total mass of the products (the substances formed as a result of the reaction).

Applying the Law of Conservation of Mass to Combustion

When a chemical is ignited and completely burned, the reactants (the fuel source and oxygen) are converted into products (carbon dioxide, water vapor, and other gases). According to the Law of Conservation of Mass, the total mass of the reactants must be equal to the total mass of the products.

The Role of the Balance

A balance is a scientific instrument used to measure the mass of a substance. In the context of combustion, a balance is used to measure the mass of the fuel source before and after it is ignited and burned.

What will the balance read after the chemical is ignited and completely burned?

Given the Law of Conservation of Mass, it is clear that the balance will read the same after the chemical is ignited and completely burned as it did before the reaction. This is because the total mass of the reactants (the fuel source and oxygen) is equal to the total mass of the products (carbon dioxide, water vapor, and other gases).

The Correct Answer

Based on the Law of Conservation of Mass, the correct answer is:

A. The balance will read 100.0 g.

This answer assumes that the initial mass of the fuel source is 100.0 g. Since the total mass of the reactants is equal to the total mass of the products, the balance will read the same after the chemical is ignited and completely burned.

The Other Options

The other options are incorrect because they do not take into account the Law of Conservation of Mass.

B. It is not possible to know what the balance will read without knowing the identity of the chemical.

This option is incorrect because the Law of Conservation of Mass applies to all chemical reactions, regardless of the identity of the chemical.

C. The balance will read less than 100.0 g.

This option is incorrect because the total mass of the products is equal to the total mass of the reactants, so the balance will read the same after the chemical is ignited and completely burned.

Conclusion

In conclusion, the balance will read the same after the chemical is ignited and completely burned as it did before the reaction, assuming that the initial mass of the fuel source is 100.0 g. This is a direct result of the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction.

Understanding the Implications of the Law of Conservation of Mass

The Law of Conservation of Mass has far-reaching implications in chemistry and other fields. It provides a fundamental principle for understanding the behavior of matter and energy in chemical reactions. By applying this principle, scientists and engineers can design and optimize chemical processes, predict the outcomes of reactions, and develop new technologies.

The Importance of Balances in Chemistry

Balances are essential tools in chemistry, allowing scientists to measure the mass of substances with high precision. By using balances, chemists can track the changes in mass that occur during chemical reactions, providing valuable insights into the underlying mechanisms of these processes.

The Future of Chemistry

As chemistry continues to evolve, the importance of the Law of Conservation of Mass and the role of balances in chemistry will only continue to grow. By understanding and applying these fundamental principles, scientists and engineers will be able to develop new technologies, improve existing processes, and advance our knowledge of the natural world.

Q: What is the Law of Conservation of Mass?

A: The Law of Conservation of Mass is a fundamental principle in chemistry that states that matter cannot be created or destroyed in a chemical reaction. This means that the total mass of the reactants (the substances involved in the reaction) is equal to the total mass of the products (the substances formed as a result of the reaction).

Q: Why is the balance reading the same after the chemical is ignited and completely burned?

A: The balance is reading the same after the chemical is ignited and completely burned because the total mass of the reactants is equal to the total mass of the products. This is a direct result of the Law of Conservation of Mass.

Q: What happens to the mass of the fuel source during combustion?

A: During combustion, the mass of the fuel source is converted into the mass of the products (carbon dioxide, water vapor, and other gases). However, the total mass of the reactants (the fuel source and oxygen) is equal to the total mass of the products.

Q: Can the balance read a different value after the chemical is ignited and completely burned?

A: No, the balance cannot read a different value after the chemical is ignited and completely burned. This is because the Law of Conservation of Mass ensures that the total mass of the reactants is equal to the total mass of the products.

Q: What is the significance of the balance in chemistry?

A: The balance is a crucial tool in chemistry, allowing scientists to measure the mass of substances with high precision. By using balances, chemists can track the changes in mass that occur during chemical reactions, providing valuable insights into the underlying mechanisms of these processes.
