turn: 1
modality: image
input: Generate a concise chemical laboratory bench scene: A substance is contained in a <sealed glass reagent bottle>. The substance must have the following observable appearance: <white, solid, irregular lumps or coarse powder, opaque, no metallic luster>. The background should be a <clean laboratory bench with basic equipment outlines, avoiding clutter and text labels>.
output: evaluation_points: 1. The generated container is correct and is indeed a <sealed glass reagent bottle>.

2. The color and physical form (lumps/coarse powder) of the target substance conform to '<white, solid, irregular lumps or coarse powder>'.

3. The substance is appropriately contained in the bottle, with a suitable quantity.

4. The background is a simple laboratory bench scene.

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 reacts vigorously with water, releasing a significant amount of heat. 2. It is commonly used as a drying agent. 3. It is a basic oxide.>, which of the following substances is it most likely to be?
Options:
A. Sodium Chloride (NaCl)
B. Calcium Oxide (CaO)
C. Silicon Dioxide (SiO₂)
D. Copper(II) Sulfate Pentahydrate (CuSO₄·5H₂O)
E. None of the above
output: answer: B

turn: 3
modality: image
input: We will now refer to the substance you identified in the previous question as the 'target substance'. The target substance can undergo <a reaction with water, releasing a significant amount of heat>. Please generate the state of the experimental setup on the bench during this normal reaction (the experimental apparatus, the state of the substances, and the reaction phenomena should all be reasonable and self-consistent).
output: evaluation_points: 1. The selection, connection, and use of experimental instruments are correct and match the <exothermic reaction of calcium oxide with water>.

The target substance (calcium oxide) is generated in the correct form (white lumps/powder) and in the correct location (e.g., in a beaker), with its color and state conforming to the description in turn 1 input: '<white, solid, irregular lumps or coarse powder, opaque, no metallic luster>'.

3. The reactant (water) is correctly depicted in the image with its proper color, state (liquid), and location (e.g., being poured from a wash bottle or already in the beaker).

4. The reaction phenomenon conforms to '<vigorous reaction, possible steam/vapor visible due to heat release, the solid may crumble or dissolve>'. The apparatus (e.g., beaker) should be shown, and safety considerations like handling a hot container can be implied.

The picture background is a clean laboratory bench with basic equipment outlines, avoiding clutter and text labels, consistent with the background requirement from turn 1 input: '<clean laboratory bench with basic equipment outlines, avoiding clutter and text labels>'.

input: If, in the normal reaction described above, the experimental procedure is mistakenly altered by <adding a large amount of the target substance (lumps) rapidly into a small volume of water in a confined container like a sealed test tube>, what is the most likely accident to occur?
Options:
A. A violent exothermic reaction causing rapid steam generation and potential pressure buildup, leading to container rupture or ejection of hot contents.
B. The formation of a non-hazardous, cold precipitate with no safety risk.
C. A slow, endothermic reaction that absorbs heat from the surroundings, causing the apparatus to freeze.
D. The immediate release of a large volume of flammable and toxic gas.
E. None of the above
output: answer: A

turn: 5
modality: text
input: Regarding the experimental accident described in the previous question, what is the most correct immediate response?
Options:
A. Immediately seal the container more tightly to contain the pressure and reaction.
B. Evacuate the immediate area, alert others, and allow the reaction to complete in a fume hood or safe location from a distance. Do not approach the hot or potentially rupturing container until it has completely cooled.
C. Pour more water into the container to dilute and cool the reaction mixture rapidly.
D. Use a Bunsen burner to apply direct heat to the container to speed up the reaction and relieve pressure.
E. None of the above
output: answer: B
