Explain why the melting of the chocolate bar is a physical change and not a chemical change.

— Its chemical composition remains the same.
— It is still the same substance/chocolate.
— No new substance was formed.
— It just changed its shape.
— Only the state of matter/phase changed.
Which evidence in the diagram indicates that a gas was produced as a result of the reaction?

— Gas bubbles were formed.
— bubbles in the liquid
— The balloon filled up with gas/carbon dioxide gas.
