Question

What is always true according to the law of conservation of matter with the answer would be Adams can be rearranged during a chemical reaction, but cannot be added or taken away or would it be new molecules cannot be formed from the reactants during a chemical reaction or would it be the total number of molecules before and after a chemical reaction stays the same, and last would it be Adams created during a chemical reaction must have the same mass as the Adams and the reactants

Answer 1

According to the law of conservation of matter, the correct statement is that **atoms can be rearranged during a chemical reaction, but cannot be created or destroyed**. This means that the total number of atoms remains constant before and after a chemical reaction.

To break down the statements you provided:

1. **Atoms can be rearranged during a chemical reaction, but cannot be added or taken away.** - This statement is true and reflects the law of conservation of matter accurately.

2. **New molecules cannot be formed from the reactants during a chemical reaction.** - This statement is false. New molecules can be formed; the atoms simply rearrange to create them.

3. **The total number of molecules before and after a chemical reaction stays the same.** - This statement can be misleading. While the total number of atoms remains the same, the number of molecules can change depending on the reaction.

4. **Atoms created during a chemical reaction must have the same mass as the atoms in the reactants.** - This statement is partially true, as the mass is conserved, but it implies the creation of atoms, which is false. Atoms are not created or destroyed in a chemical reaction; they are rearranged.

So, the first statement is the best reflection of the law of conservation of matter.
