turn: 1
modality: image
input: Please generate a concise chemical laboratory bench scene: A substance is contained in a <beaker>. This substance must have the following observable appearance: <silvery-gray solid, lustrous, in the form of irregular granules or small pieces>. 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 (irregular granules/small pieces) of the target substance conform to 'silvery-gray solid, lustrous'.

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 a moderately reactive metal that readily reacts with dilute acids to produce hydrogen gas. 2. It has a relatively low melting point for a metal (approx. 420°C). 3. It is a good conductor of electricity.>, which of the following substances is it most likely to be?

Options:
A. Copper (Cu) - reddish-brown solid, excellent conductor, does not readily react with dilute acids.
B. Zinc (Zn) - bluish-silvery solid, good conductor, reacts with dilute acids to produce hydrogen gas.
C. Sulfur (S) - yellow solid powder, poor conductor, does not react with dilute acids to produce gas.
D. Sodium Chloride (NaCl) - white crystalline solid, poor conductor in solid state, dissolves in water but does not react with dilute acids to produce gas.
E. None of the above.
output: answer: B

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 apparatus are correct and match the reaction of zinc with dilute hydrochloric acid.

The target substance is generated in the correct form, location, and its color (silvery-gray) and state (solid granules) conform to the characteristics described in turn 1 input: 'silvery-gray solid, lustrous, in the form of irregular granules or small pieces'.

The reactant (dilute hydrochloric acid) is generated as a colorless solution, with the correct state and location (e.g., in a beaker or test tube).

4. The reaction phenomenon conforms to 'vigorous effervescence of a colorless gas (hydrogen) from the surface of the solid granules'.

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 test tube) instead of an open one>, what is the most likely accident to occur?

Options:
A. The acid solution boils over due to overheating.
B. Pressure buildup inside the sealed container causes it to rupture or the stopper to be ejected violently.
C. The metal spontaneously ignites, causing a fire.
D. A toxic gas (like chlorine) is produced and leaks.
E. None of the above.
output: answer: B

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

Options:
A. Immediately open the sealed container to release the pressure.
B. Evacuate the area immediately, alert others, and allow the reaction to subside from a safe distance before cautiously approaching to assess and clean up any spills while wearing appropriate PPE.
C. Pour water onto the container to cool it down.
D. Use a fire extinguisher on the apparatus.
E. None of the above.
output: answer: B
