turn: 1
modality: image
input: Please generate a concise chemical laboratory bench scene: A substance is contained in a <beaker>. The substance must have the following observable characteristics: <white solid, in the form of a fine powder, opaque>. 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 beaker.

2. The color and appearance (fine powder) of the target substance conform to 'white solid powder'.

3. The substance is appropriately contained in the beaker 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 is insoluble in water. 2. It reacts with dilute acids to produce a colorless gas. 3. It decomposes upon strong heating to produce a different colorless gas and a solid oxide.>, which of the following substances is it most likely to be?

Options:
A. Sodium Chloride (NaCl)
B. Calcium Carbonate (CaCO3)
C. Copper(II) Sulfate Pentahydrate (CuSO4·5H2O)
D. Sulfur (S)
E. None of the above
output: answer: B

turn: 3

input: We will subsequently refer to the substance you identified earlier as the 'target substance'. The target substance can undergo <a reaction with dilute hydrochloric acid, producing a gas>. Please generate the state of the experiment 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 reaction of calcium carbonate with dilute hydrochloric acid.

The target substance (calcium carbonate) is generated in the correct form (white solid, in the form of a fine powder, opaque) in the correct location (e.g., in a beaker or test tube).

3. The reactant (dilute hydrochloric acid, a colorless solution) is generated with the correct color, state, and location.

4. The reaction phenomenon conforms to 'vigorous effervescence (bubbling) of a colorless gas'.

5. The picture background is a laboratory bench.

input: If, in the above normal reaction, the experimental setup is incorrectly modified by <using a sealed container (e.g., a stoppered flask) to collect the gas produced>, what is the most likely accident to occur?

Options:
A. The reaction mixture overheats and boils over.
B. Pressure builds up inside the sealed container, potentially causing it to rupture or the stopper to be ejected violently.
C. The acid spills and causes a chemical burn.
D. The gas produced ignites, causing an explosion.
E. None of the above
output: answer: B

modality: text
input: Regarding the experimental accident described in the previous question, what is the most correct way to handle it?

Options:
A. Immediately add a base to neutralize the acid.
B. Quickly move the sealed container to a fume hood and carefully release the pressure by loosening the stopper away from yourself and others, while wearing appropriate PPE.
C. Submerge the sealed container in cold water to cool it down.
D. Ignore it and wait for the pressure to equalize on its own.
E. None of the above
output: answer: B
