Final answer:
To determine the accelerant, compare the heat energy released by each reaction. Acetone is the accelerant under the threshold.
Step-by-step explanation:
To determine which liquid is the accelerant, we need to compare the heat energy released by each reaction. The heat energy released is given by the ΔH value.
Let's calculate the heat energy released by each reaction:
- Acetone: ΔH = -9.6 x 10 kJ
- Coleman Fuel: ΔH = Unknown
- Ethyl alcohol: ΔH = Unknown
- Mineral Spirits: ΔH = Unknown
- Turpentine: ΔH = Unknown
From the information provided, we only have the ΔH value for acetone, which is -9.6 x 10 kJ. Therefore, we can conclude that acetone is the accelerant under the threshold.
