turn: 1
modality: image
input: Generate a single element tile from the periodic table. The element must satisfy the following criteria: It is a metal located in Period 4 and Group 2. Its atom has 20 protons. 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 the shape of a single tile from the periodic table.

2. The element symbol 'Ca' must be correctly labeled in the center of the tile.

3. The atomic number '20' must be correctly labeled in the top-right corner of the tile.

4. The image should be simple and flat in style, containing only the single periodic table tile with no additional elements.

turn: 2
modality: text
input: Based on the element symbol and atomic number from the input image, consider the following: If this element can combine with oxygen (O) to form a substance, and this substance has the property of reacting vigorously with water to release a significant amount of heat and produce a basic solution, what is the most likely substance formed?

Options:
A. Calcium Carbonate (CaCO₃)
B. Calcium Oxide (CaO)
C. Calcium Hydroxide (Ca(OH)₂)
D. Calcium Sulfate (CaSO₄)
E. None of the above
output: answer: B

turn: 3
modality: image
input: We will refer to the substance you identified in the previous text as the 'Target Substance'. Now, there are two test tubes placed side-by-side. The left test tube contains an appropriate amount of Dilute Hydrochloric Acid (HCl, aq). The right test tube contains an appropriate amount of Concentrated Sulfuric Acid (H₂SO₄, conc.). An identical amount of the solid Target Substance 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 should be a simple laboratory bench.
output: evaluation_points: 1. The image must depict exactly two test tubes, placed side-by-side (left and right), with a safe and reasonable volume of liquid in each.

2. The solution colors must match the following: The left tube contains a colorless dilute hydrochloric acid solution. The right tube contains a colorless concentrated sulfuric acid solution.

The phenomenon in the left tube must match: The solid Target Substance (which is Calcium Oxide, CaO, as identified in Turn 2) reacts vigorously with dilute hydrochloric acid, dissolving completely and producing a clear, colorless solution. The reaction is exothermic, which may be indicated by slight vapor or heat lines, but no gas bubbles should be prominent.

The phenomenon in the right tube must match: The solid Target Substance (which is Calcium Oxide, CaO, as identified in Turn 2) reacts with concentrated sulfuric acid to form a white precipitate of calcium sulfate (CaSO₄), which is sparingly soluble. The solid may appear to be coated or surrounded by the white precipitate, and the reaction is less vigorous compared to the left tube, with minimal dissolution.

5. The image background must be a simple laboratory experiment table.

turn: 4
modality: text
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 formation of an insoluble product (precipitate) in one reaction passivates the surface of the solid, inhibiting further reaction.
C. One acid is oxidizing while the other is not, leading to different redox products.
D. The difference in acid strength leads to different extents of dissociation and proton availability.
E. None of the above.
output: answer: B
