turn: 1
modality: image
input: Please 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 characteristics: <must include color + physical state (solid/liquid/gas) + form (powder/lump/crystal/solution, etc.) + optional luster/transparency; the substance name, chemical formula, or element symbols are 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 indeed matches the container type described in the prompt.

2. The color and appearance (powder/crystal/lump/solution, etc.) of the target substance conform to the morphological features described in the prompt: 'white, solid, pellet or flake form, opaque', and it is not depicted as a solution or powder.

3. The substance is appropriately contained in the vessel (e.g., a beaker or watch glass) with a suitable quantity, and there are no special storage requirements depicted (it is not shown stored under oil).

4. The background is a clean and 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 is highly soluble in water, releasing a significant amount of heat upon dissolution. 2) Its aqueous solution feels slippery to the touch. 3) It readily absorbs moisture and carbon dioxide from the air. Which of the following substances is it most likely to be?

Options:
A. Sodium Chloride (NaCl, common table salt)
B. Calcium Oxide (CaO, quicklime)
C. Sodium Hydroxide (NaOH)
D. Anhydrous Copper(II) Sulfate (CuSO₄)
E. None of the above
output: answer: C

modality: image
input: We will now refer to the substance you identified earlier as the 'target substance'. The target substance can undergo a reaction described as follows: 'It reacts vigorously with dilute hydrochloric acid, releasing a gas and generating significant heat.' Please generate the state of the laboratory bench during this normal reaction, ensuring the experimental apparatus, states of the substances, and reaction phenomena are all reasonable and self-consistent.
output: evaluation_points: 1. The selection, connection, and use of experimental instruments are correct and match the requirements for the reaction described in the prompt: 'It reacts vigorously with dilute hydrochloric acid, releasing a gas and generating significant heat.'

2. The target substance is depicted in the correct form (white pellets/flakes) in the appropriate location within the apparatus (e.g., a beaker or flask), and its color and state are consistent with the characteristics described for the substance in Turn 1's prompt: 'white, solid, pellet or flake form, opaque'.

3. The reactant (dilute hydrochloric acid) is correctly shown in the image with its appropriate color (colorless), state (liquid), and location (e.g., being added from a dropper or burette).

4. The reaction phenomenon is consistent with the reaction described in the prompt: 'It reacts vigorously with dilute hydrochloric acid, releasing a gas and generating significant heat.' There should be visual cues indicating the release of gas (e.g., bubbles) and potentially heat (steam, though the reaction itself may not produce visible steam, the apparatus could be depicted as warm).

5. The image background is a laboratory bench.

input: If, in the normal reaction described above, the experimental setup was incorrectly modified by 'using a sealed container instead of an open or vented one for the vigorous acid-base reaction', what is the most likely accident to occur?

Options:
A. A violent explosion due to rapid pressure buildup from gas release.
B. Splashing of corrosive liquids causing chemical burns.
C. Ignition of flammable vapors produced by the reaction.
D. Leakage of toxic chlorine gas.
E. None of the above
output: answer: A

input: Regarding the laboratory accident described in the previous question, what is the most correct immediate response?

Options:
A. Immediately evacuate the area, alert others, and let the pressure subside from a safe distance before approaching.
B. Use a fire extinguisher to cool down the overheated container.
C. Neutralize the spilled chemicals with a base like sodium bicarbonate.
D. Attempt to quickly open the sealed container to release the pressure.
E. None of the above
output: answer: A
