input: 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 appearance: <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 only, avoid clutter and text labels>.
output: evaluation_points: 1. The generated container is correct and is indeed a <glass reagent bottle with a ground glass stopper>.

2. The color and appearance (form) of the target substance conform to '<colorless, viscous liquid>'. It should appear as a clear, thick, oily liquid.

3. The substance is correctly contained in the bottle, filled to a safe and appropriate level (e.g., 2/3 full).

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 strong diprotic acid. 2) It is highly hygroscopic and has a very high affinity for water. 3) It is a dense, oily liquid at room temperature. Which of the following substances is it most likely to be?

Options:
A. Concentrated Nitric Acid (HNO3)
B. Concentrated Hydrochloric Acid (HCl)
C. Concentrated Sulfuric Acid (H2SO4)
D. Glacial Acetic Acid (CH3COOH)
E. None of the above
output: answer: C

input: We will now refer to the substance you identified earlier as the 'target substance'. There are two test tubes placed side-by-side. The left test tube contains an appropriate amount of Acid A = <dilute hydrochloric acid (HCl) solution>, and the right test tube contains an appropriate amount of Acid B = <concentrated nitric acid (HNO3) solution>. An identical sample of the target substance (in solid form) is simultaneously added to both tubes. Please generate an image representing the phenomena in both test tubes at the same moment during the reaction. The background is a simple laboratory bench.
output: evaluation_points: 1. The image accurately depicts two test tubes, placed side-by-side (left and right). The liquid volume in each tube is safe and reasonable (e.g., half-full).

2. The solution colors match the description: 'The left tube contains a colorless dilute hydrochloric acid solution. The right tube contains a colorless concentrated nitric acid solution.'

The solution colors match the description: 'The left tube contains a colorless dilute hydrochloric acid solution. The right tube contains a colorless concentrated nitric acid solution.'

The phenomenon in the left tube conforms to the setting: 'Vigorous effervescence (bubbling) occurs as the solid reacts with dilute HCl, producing a colorless gas. The solid may dissolve.'

The phenomenon in the right tube conforms to the setting: 'No visible reaction (or extremely slow reaction/passivation) occurs. The concentrated nitric acid may cause slight surface oxidation, but no significant gas evolution or dissolution is observed.'

input: Based on the difference in phenomena observed in the two test tubes in the input image, what is the most fundamental reason for this difference?

Options:
A. The difference in acid concentration affects the reaction rate.
B. The oxidizing power of the acids differs, with one causing passivation of the metal surface.
C. One acid is a strong oxidizing agent while the other is not, leading to different reaction products and mechanisms.
D. The target substance is amphoteric and reacts differently with strong vs. weak acids.
E. None of the above
output: answer: B
