Based on the description of the scenario, the following responses are most likely applicable:
1. **The two substances chemically reacted to form new substances.**
- This is supported by the information that a reaction occurred with a burst of heat (in the form of light) and resulted in the formation of a new substance (the white powder).
2. **There was a temperature increase during this change.**
- This is also supported by the details provided, as it mentions a burst of heat indicating an exothermic reaction.
Therefore, the correct responses would be:
- The two substances chemically reacted to form new substances.
- There was a temperature increase during this change.
The other options do not accurately describe what happened during the reaction.
