Which procedure could be used to demonstrate that matter is conserved during a chemical change or reaction?
One procedure that could be used to demonstrate the conservation of matter during a chemical change or reaction is to carefully measure the mass of all the reactants and products involved before and after the reaction. This can be done using a balance or scale. By comparing the mass of the reactants to the mass of the products, if they are found to be equal, it can be concluded that matter is conserved during the chemical change or reaction.
To demonstrate that matter is conserved during a chemical change or reaction, you can use the procedure called "a balanced chemical equation." Here are the steps:
1. Identify the reactants and products: Determine the substances that are present at the start of the reaction (reactants) and those that are formed as a result of the reaction (products).
2. Write the balanced equation: Write a chemical equation that represents the reaction, ensuring that the number of atoms of each element is the same on both sides of the equation. This principle is known as the Law of Conservation of Mass.
3. Count the atoms: Count the number of atoms of each element on both sides of the equation to verify that they are equal. This demonstrates that matter is conserved during the chemical change.
By following these steps, you can illustrate the conservation of matter during a chemical reaction.
