Using the graph, describe how the mass before the reaction compares to the mass after the reaction.
Which statement is best supported by the data?
Using the investigation description, explain why the container being sealed is important.
How does this investigation show that the system behaves the same before and after the reaction?
Which conclusion is best supported by the investigation?
A student claims: “Mass is conserved during a chemical reaction when the reaction occurs in a closed system.” Do you agree or disagree? Use evidence from the investigation to support your answer.
