modality: text
input: Which of the following substances are consistent with the description: 'A dark red to purple solid, stable in air at room temperature, insoluble in water and common organic solvents, and capable of undergoing combustion to produce dense white smoke'?
Options:
A. Sulfur (S)
B. Iodine (I₂)
C. Red Phosphorus (P)
D. Potassium Permanganate (KMnO₄)
E. None of the above
output: answer: C

turn: 2
modality: image
input: It is known that the target substance is one of the correct options from the previous question. Furthermore, it has the following additional property: It is a non-metallic allotrope that must be stored in a tightly sealed container, away from oxidizers and heat sources, due to its potential to ignite upon friction or heating. Please generate an image showing this target substance stored correctly in its proper container and placed on a laboratory bench.
output: evaluation_points: 1. The container generated in the image is correct; it is indeed a tightly sealed, labeled glass or plastic reagent bottle.

2. The substance generated in the image is indeed Red Phosphorus, with a color and appearance (amorphous powder or small lumps) consistent with the description 'a dark red to purple solid' from Turn 1.

3. The substance is correctly contained within the sealed bottle, with an appropriate fill level (e.g., not overflowing). There is no special liquid storage medium required.

4. The background is a simple laboratory bench scene.

turn: 3
modality: image
input: We will subsequently refer to the substance you identified earlier as the 'target substance'. The target substance can undergo vigorous combustion in air or oxygen when ignited, producing a characteristic dense white smoke of phosphorus pentoxide. Please generate the state of the laboratory bench during this normal reaction, with experimental apparatus, substance states, and reaction phenomena all being reasonable and self-consistent.
output: evaluation_points: 1. The selection, connection, and use of experimental apparatus are correct and match the combustion reaction of red phosphorus. This should include a heat source (e.g., Bunsen burner), a suitable holder (e.g., deflagrating spoon or crucible), and safety equipment.

2. The target substance (red phosphorus) is generated in the correct form (powder/lumps) in the correct location (e.g., in the spoon/crucible over the flame), with color and state consistent with 'Red Phosphorus as a dark red solid'.

2. The target substance (red phosphorus) is generated in the correct form (powder/lumps) in the correct location (e.g., in the spoon/crucible over the flame), with color and state consistent with the description 'a dark red to purple solid' from Turn 1.

4. The reaction phenomenon matches 'vigorous combustion producing dense white smoke (P₄O₁₀)'. Flames and copious white smoke should be visible.

5. The picture background is a laboratory bench.

modality: text
input: If, in the normal combustion reaction described above, the experimental conditions were mistakenly altered by using a large, open container (like a beaker) to hold a substantial quantity of the target substance powder loosely, instead of a small amount in a controlled apparatus, what is the most likely accident to occur?
Options:
A. A slow, controlled oxidation producing only mild heat.
B. A violent, uncontrolled combustion or deflagration, potentially causing a fire and spreading burning material.
C. The substance dissolving harmlessly in atmospheric moisture.
D. A color change of the substance without any energy release.
E. None of the above.
output: answer: B

turn: 5
modality: image
input: Please generate the scene of the experimental accident described in the previous question, and demonstrate the correct way to handle this accident.
output: evaluation_points: 1. The image correctly depicts the aftermath of the accident: an uncontrolled fire or vigorous burning of red phosphorus powder in/around a large beaker on the bench, with significant flames and dense white smoke.

2. The image shows the correct accident handling method, satisfying 'using a fire blanket, sand, or a Class D fire extinguisher (for metal fires, also suitable for phosphorus) to smother the fire, NOT using water or a standard CO₂ extinguisher which could spread burning particles'.

3. The background and other unrelated elements remain consistent with the reaction image generated earlier (same lab bench), with no significant changes.

3. The background and other unrelated elements remain consistent with the laboratory bench background from Turn 2 output image, with no significant changes.
