turn: 1
modality: image
input: Generate a concise chemical laboratory bench scene: A substance is contained in a <correct and suitable laboratory container type>. The substance must exhibit the following observable appearance: <color + physical state (solid/liquid/gas) + form (powder/lump/crystal/solution, etc.) + optional luster/transparency; the name, chemical formula, or element symbol of the substance is prohibited>. The background should be a <laboratory environment: bench surface, outlines of basic equipment, avoid clutter and text labels>.
output: evaluation_points: 1. The container generated in the image is correct and is indeed a <wide-mouth reagent bottle or a sample vial>.

2. The color and appearance (powder/crystal/lump/solution, etc.) of the target substance conform to 'a fine, dark gray to black powder'.

3. The substance is appropriately contained in the bottle (no special storage requirements like sodium in kerosene are needed here), and the quantity is suitable.

4. The background is a simple laboratory bench scene.

turn: 2
modality: text
input: Based on the appearance of the substance in the input image, and given that this substance is known to have the following properties: 1) It is strongly attracted by a magnet. 2) It reacts with dilute hydrochloric acid to produce a gas that burns with a pale blue flame. 3) It is a good conductor of electricity. Which of the following substances is it most likely to be?
Options:
A. Copper(II) oxide powder (CuO)
B. Activated charcoal powder (C)
C. Reduced iron powder (Fe)
D. Aluminum powder (Al)
E. None of the above
output: answer: C

turn: 3
modality: text
input: In the previous context, the substance you identified (referred to as the 'target substance') is commonly used as the main active ingredient or core functional component in which of the following household items/products?
Options:
A. Hand warmer (disposable, air-activated type)
B. Laundry detergent (for stain removal)
C. Antacid tablet (for heartburn relief)
D. Water filter cartridge (for heavy metal removal)
E. None of the above
output: answer: A

turn: 4
modality: image
input: Generate a real-life scene: Using the household item corresponding to the correct option from the previous question, treat <the name of the object being treated, which is appropriate for the use of the item selected in the previous round, e.g., 'hands feeling cold on a winter day'; the name or chemical formula of the FH substance is prohibited>. The image should naturally show a directly observable change 'before/after treatment or during the treatment process'.
output: evaluation_points: 1. The scene depicted in the image conforms to the 'hands feeling cold on a winter day' scenario described in the stem, and the setting and target are reasonable.

2. The scene correctly features a <disposable hand warmer packet> and its usage conforms to common practice (e.g., held in hands or placed in a pocket). The hand warmer packet should be consistent with the substance identified in turn 2 (reduced iron powder, Fe).

3. There is a clearly observable change during the process: <The originally flat, flexible hand warmer packet becomes noticeably warm to the touch and may swell slightly as the internal contents react and generate heat>.

turn: 5
modality: text
input: Based on the life phenomenon in the input image and the judgments you made in the previous context, determine which of the following chemical reaction equations represents the process occurring?
Options:
A. 4Fe(s) + 3O₂(g) → 2Fe₂O₃(s) (Combustion in air)
B. 2Fe(s) + O₂(g) + 2H₂O(l) → 2Fe(OH)₂(s) (Room temperature, aqueous)
C. 4Fe(s) + 3O₂(g) + 6H₂O(l) → 4Fe(OH)₃(s) (Room temperature, catalyzed by salt)
D. Fe(s) + 2H⁺(aq) → Fe²⁺(aq) + H₂(g) (Reaction with acid)
E. None of the above
output: answer: C
