input: Generate a single element tile from the periodic table. The element must satisfy the following criteria: It is a transition metal located in the fourth period and belongs to Group 11. Its common stable oxidation state is +2. 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 clean, flat-style graphic of just the single tile with no other content.
output: evaluation_points: 1. The generated content generally resembles a single tile from the periodic table.

2. The element symbol 'Cu' is correctly placed in the center of the tile.

3. The atomic number '29' is correctly placed in the top right corner of the tile.

4. The image is clean, in a flat graphic style, containing only the single periodic table tile with no extraneous elements.

input: Based on the element symbol and atomic number from the input image, determine the following: If this element can combine with the sulfate ion (SO4^2-) to form a compound, and this compound has the following properties: it is a blue crystalline solid, highly soluble in water, and its aqueous solution is acidic due to hydrolysis, then what is the most likely compound formed?

Options:
A. Copper(II) Oxide (CuO)
B. Copper(II) Sulfate (CuSO4)
C. Copper(I) Sulfide (Cu2S)
D. Copper(II) Carbonate (CuCO3)
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'. In the process of preparing this target substance from copper metal and concentrated sulfuric acid under heating, a specific piece of laboratory glassware is essential. Please generate an image depicting the correct use of this instrument in that reaction scenario. The background should be a simple laboratory bench.
output: evaluation_points: 1. The image correctly depicts a round-bottom flask, and it is positioned appropriately on the lab bench, likely on a heating mantle or supported by a clamp and stand.

The reaction setup is consistent with the described preparation: copper metal pieces/reactant and concentrated sulfuric acid should be present in the flask, with a heat source applied (e.g., a heating mantle beneath). The described preparation is from turn 3 input text: 'preparing this target substance from copper metal and concentrated sulfuric acid under heating'.

The round-bottom flask is used correctly: it is securely clamped by its neck, not its body, and is connected to appropriate apparatus for heating and gas evolution (e.g., a gas delivery tube or condenser, though a simple setup for SO2 evolution may be shown).

The background is a clean, simple laboratory bench scene, as required by the turn 3 input text: 'The background should be a simple laboratory bench.'

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

Options:
A. This glassware is specifically designed to withstand uniform heating and is commonly used for reflux and distillation setups.
B. When heating the contents of this flask, it must always be placed directly on a wire gauze over a Bunsen burner.
C. A key safety practice is to never heat a sealed system using this flask, to avoid pressure buildup and explosion.
D. For reactions involving vigorous boiling or potential bumping, adding boiling chips or a magnetic stir bar to this flask is a standard procedure.
E. This type of flask is typically used for precise volumetric measurements and preparing standard solutions.
F. It is acceptable to clamp this flask tightly around its spherical body for support during heating.
G. None of the above options are correct.
output: answer: A, C, D
