Exit Ticket
Based on this, we can say a chemical reaction did occur during the Mixing Substances Investigation. Because a reaction occurred, we will call it the Hot Yellow Gas Reaction. We know it is a reaction because there was a color change, a temperature change, and gas was produced. We can call it the HYG Reaction for short.

After:

Hot Yellow Gas Reaction. HYG Reaction for short.
