turn: 1
modality: image
input: Generate a single element tile from the periodic table. The element must satisfy the following criteria: It is a nonmetal in Period 2, Group 15 (VA). Its atom has 5 valence electrons. The tile should contain: the correct element symbol in the center, and the correct atomic number in the top right corner. The image should be a simple, flat-style graphic of a single periodic table tile with no other content.
output: evaluation_points: 1. The generated content should generally resemble a single tile from the periodic table (rectangular shape, clear borders).

2. The tile's center must correctly display the element symbol: N.

3. The tile's top right corner must correctly display the atomic number: 7.

4. The image is clean, in a flat graphic style, and contains no content other than the single periodic table tile.

turn: 2

input: Based on the element symbol and atomic number from the input image, determine the following: If this element can combine with hydrogen ions (H+) to form a substance, and this substance has the following properties: it is a colorless, aqueous solution with a pungent odor, and it is a weak base that can turn moist red litmus paper blue, then what is the most likely substance formed?

Options:
A. Nitric Acid (HNO3)
B. Ammonia Solution (NH3·H2O)
C. Hydrazine (N2H4)
D. Ammonium Chloride (NH4Cl)
E. None of the above
output: answer: B

turn: 3
modality: image
input: We will now refer to the substance you identified in the previous question as the 'target substance'. Please generate an image depicting the correct usage scenario for the laboratory instrument 'Ammonia Fountain Apparatus' during an experiment designed to demonstrate the high solubility and basic nature of the target substance in water. The background should be a simple laboratory bench.
output: evaluation_points: 1. The image correctly depicts an 'Ammonia Fountain Apparatus'. This should include a round-bottom flask (for ammonia gas), a drying tube or delivery tube, and a receiving flask or beaker containing water with an indicator (like phenolphthalein). The apparatus setup should be logical and clear.

The depicted reaction/scene should be consistent with demonstrating ammonia's properties: The round-bottom flask should imply it contains a source of ammonia gas (e.g., from heating an ammonium salt with a base). The receiving vessel's water should be shown or implied to contain an indicator that would turn pink upon contact with the basic ammonia solution. (The target substance is Ammonia Solution (NH3·H2O) as identified in turn 2.)

3. The use of the Ammonia Fountain Apparatus should follow safety and procedural norms: Connections should be airtight, the setup should allow gas to be generated into the water (often by creating a pressure difference, e.g., by cooling the round-bottom flask or adding water to dissolve the gas).

4. The background is a simple, uncluttered laboratory bench scene.

turn: 4
modality: text
input: Based on the instrument and operational scene in the input image, judge which of the following statements about this instrument and its usage norms are correct.

Options:
A. This apparatus is primarily used to demonstrate the low solubility of gases in water.
B. The receiving flask typically contains an acidic solution with a colored indicator.
C. The experiment often utilizes the high solubility of ammonia gas in water to create a pressure difference, driving the fountain effect.
D. It is safe to use concentrated sulfuric acid in the receiving flask for this demonstration.
E. A common safety precaution is to ensure all glassware connections are secure to prevent gas leaks.
F. The color change observed in the fountain (e.g., to pink) is due to the formation of an acidic solution.
G. None of the above are correct.
output: answer: C, E
