What procedure could be used to demonstrate that matter is conserved during a chemical change or reaction?

Find the mass of a piece of ice. Let the ice melt. Find the mass of the liquid water.

It’s physical change not chemical

find the mass of an acid and a base. combine them to produce water and a salt. find the mass of the water and the salt.

Which procedure could be used to demonstrate that matter is conserved during a chemical change or reaction?

To demonstrate that matter is conserved during a chemical change or reaction, you can use the procedure known as mass balance or mass conservation. Here's how you can carry out this procedure:

1. Gather the necessary equipment: You'll need a balanced chemical equation representing the reaction you want to investigate, a digital balance or scale, and all the reactants and products required for the reaction.

2. Set up a controlled environment: Choose a clean and dry area to perform the experiment. Ensure that the balance or scale is calibrated correctly and zeroed out.

3. Weigh the reactants: Carefully measure and record the masses of all the reactants involved in the reaction. Use the balance or scale to obtain accurate measurements.

4. Perform the reaction: Combine the reactants according to the balanced chemical equation. Follow the specified procedure and take any necessary safety precautions.

5. Collect the products: Once the reaction is complete, gather all the products of the reaction. Be careful to collect all the solid, liquid, or gaseous substances that result from the reaction.

6. Weigh the products: Place each product on the balance or scale individually and record their respective masses accurately.

7. Compare the masses: Add up the masses of all the reactants and compare it to the total mass of the products. If the masses are equal (with a small margin of error due to experimental limitations), it indicates that matter is conserved during the chemical reaction.

By following this procedure, you can demonstrate that matter is conserved during a chemical change or reaction by comparing the masses of the reactants and products. If the law of conservation of mass holds true, the total mass before the reaction should be equal to the total mass after the reaction.

You could use a closed system. Weigh the material initially, let the reaction take place and weigh the system again. It would weigh the same. Look up the experiment by Lavoisier when he decomposed HgO under a Bell Jar.

Well, to demonstrate that matter is conserved during a chemical change or reaction, you could try the "Matter Hide-and-Seek" party game! Here's how it goes: Gather all the matter substances involved in the reaction, like different elements or compounds. Then, make them play a fun game of hide-and-seek! Once they've hidden, let the chemical reaction happen and observe the outcome. After the reaction, go on a search and find mission to locate all the matter players again. If you find them all, congrats! Matter conservation is confirmed! However, if any matter is missing, you might have a few sneaky elements or compounds playing tricks on you. They must have transformed into something else during the reaction! It's like a mystery game with chemicals, and Sherlock Holmes would be proud!
