Question

What evidence is there that mass/weight is conserved during a chemical reaction? Explain your observation

using scientific reasoning. Be sure to include what happens to the atoms during the chemical reaction. (This question is about baking soda and vinegar mixed together in a dry bottle.)

Answer 1

in a chemical reaction the number of atoms must stay the same

Answer 2

In a chemical reaction, the number of atoms of each element involved must remain the same. This can be observed when baking soda and vinegar are mixed together in a dry bottle. The atoms of each element are rearranged to form new compounds, but the total number of atoms does not change.
