turn: 1
modality: image
input: Please generate a concise chemical laboratory bench scene: A substance is contained in a <correct and appropriate laboratory container type>. The substance must exhibit the following observable characteristics: <description of the target substance's observable appearance: must include color + physical state (solid/liquid/gas) + form (powder/lump/crystal/solution, etc.) + optional luster/transparency; the name, chemical formula, or element symbols of the substance are strictly 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 <gas cylinder or gas collection bottle>.

2. The color and appearance (e.g., invisible gas) of the target substance conforms to the description '<colorless, gaseous state>'.

3. The substance is correctly contained in the cylinder/bottle (no special storage requirements for H2 gas under standard lab depiction). The amount shown is appropriate.

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 the lightest element in the universe. (2) It is flammable and burns with a pale blue flame in air. (3) It is sparingly soluble in water. Please select from the following options the substance this most likely is:

A. Oxygen Gas (O2)
B. Carbon Dioxide Gas (CO2)
C. Hydrogen Gas (H2)
D. Nitrogen Gas (N2)
E. None of the above
output: answer: C

turn: 3
modality: image
input: We will subsequently refer to the substance you identified in the previous text as the 'target substance'. The target substance can undergo a reaction described as follows: 'It reacts with oxygen gas in the presence of a flame, producing water vapor and releasing a significant amount of heat.' 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 combustion reaction of hydrogen with oxygen.

The target substance (hydrogen gas) is depicted in the correct form (colorless gas) in the correct location (e.g., flowing from a gas jet or within a combustion tube). The depiction of the gas must be consistent with the description 'colorless, gaseous state' from Turn 1.

3. The reactant (oxygen from air or a source) is correctly represented in terms of color, state, and location.

4. The reaction phenomenon conforms to 'a pale blue flame being produced'.

5. The image background is a laboratory bench.

turn: 4
modality: text
input: If, in the above normal reaction, the experimental setup is incorrectly modified by 'failing to check for the purity of the hydrogen gas before igniting it', the most likely accident to occur is:

A. A violent explosion due to the presence of air (oxygen) mixed with the hydrogen.
B. The production of toxic chlorine gas.
C. The apparatus melting due to excessive heat.
D. The flame being extinguished due to insufficient gas flow.
E. None of the above
output: answer: A

turn: 5
modality: text
input: Regarding the laboratory accident described in the previous question, the most correct course of action is:

A. Immediately evacuate the area, alert others, and allow the gas to dissipate before addressing the source.
B. Attempt to reignite the gas jet to burn off the remaining impure gas.
C. Pour water over the apparatus to cool it down.
D. Quickly open all windows to increase ventilation while the reaction is ongoing.
E. None of the above
output: answer: A
