The correct response is: "it shows that no atoms have been gained or lost during the reaction."
A balanced chemical equation follows the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction. This means that the total number of atoms of each element must be equal on both sides of the equation. By balancing the equation, it ensures that the same number of atoms of each element are present before and after the reaction, demonstrating the conservation of mass.
The correct response is: "it shows that no atoms have been gained or lost during the reaction."
A balanced chemical equation demonstrates the Law of Conservation of Mass because it ensures that the number of atoms on both sides of the equation remains constant. In other words, the total mass of the reactants is equal to the total mass of the products.
To balance a chemical equation, you need to adjust the coefficients in front of the chemical formulas. Here's a step-by-step guide on how to balance a chemical equation:
1. Start by writing the chemical equation for the given reaction.
2. Count the number of atoms for each element on both sides of the equation. You can identify the number of atoms by looking at the subscripts in the chemical formulas.
3. Begin with the element that appears in the fewest compounds or appears in the most complex compounds.
4. Adjust the coefficients in front of the chemical formulas to balance the number of atoms for each element on both sides of the equation.
5. Keep in mind that you can only change coefficients, not subscripts, as altering subscripts would result in different compounds.
6. Double-check that the number of atoms for each element is the same on both sides of the equation.
7. If necessary, repeat the process by focusing on another element until you have balanced all the elements in the equation.
By balancing the equation and ensuring the conservation of mass, you are following the Law of Conservation of Mass, which states that matter cannot be created or destroyed in a chemical reaction.
