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 characteristics: <white color + solid state + powder form>. The background should be a <laboratory environment: bench surface with basic equipment outlines, avoid clutter and text labels>.
output: evaluation_points: 1. The container generated in the image is correct and is indeed a <watch glass or a small beaker>.

2. The color and physical form (powder/crystalline/lump/solution, etc.) of the target substance match the description '<white, solid powder>'.

3. The substance is appropriately contained on the watch glass/in the beaker, with a suitable quantity (e.g., a small mound).

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, odorless gas that turns limewater milky. 3) It decomposes at high temperatures to release the same type of gas. 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 Powder (S)
E. None of the above
output: answer: B

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 a moderate amount of Acid A = <Dilute Hydrochloric Acid (HCl) solution>. The right test tube contains a moderate amount of Acid B = <Acetic Acid (CH3COOH) solution>. An identical form of the target substance (e.g., powder) is simultaneously added to both tubes. Please generate an image showing 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 setting: 'The left tube contains a colorless dilute hydrochloric acid solution. The right tube contains a colorless acetic acid solution.'

The solution colors match the setting: 'The left tube contains a colorless dilute hydrochloric acid solution. The right tube contains a colorless acetic acid solution.'

The phenomenon in the left tube matches the setting: '<Vigorous effervescence (bubbling) as the target substance reacts with dilute HCl, with the solid powder visibly decreasing in quantity.>'

The phenomenon in the right tube matches the setting: '<Noticeably slower or less vigorous effervescence (bubbling) compared to the left tube, as the target substance reacts with acetic acid.>'

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 the oxidizing strength of the two acids.
B. The difference in the concentration of hydrogen ions (H+) provided by the two acids, affecting the reaction rate.
C. The formation of a passivating oxide layer on the target substance in one of the acids.
D. A difference in the solubility of the gas products in the two acid solutions.
E. None of the above
output: answer: B
