An ending substance that is made during a chemical reaction.

Product

400

How did the tokens represent a chemical reaction?

Hint: Notebook page 85

By organizing them by color for each type of atom and showing how they rearranged during the chemical reaction

400

Is this equation balanced or unbalanced?

Balanced

400

Can substances change into different substances?

yes, because atoms can be rearranged to form different substances
