turn: 1
modality: image
input: Please generate a concise chemical laboratory bench scene: A substance is contained in a <beaker>. This substance must have the following observable appearance: It is a <yellowish-brown, crystalline solid>. The background should be a <laboratory environment with a bench and basic equipment outlines, avoiding clutter and text labels>.
output: evaluation_points: 1. The container generated in the image is correct and is indeed a <beaker>.

2. The color and physical form (powder/crystalline/lump/solution, etc.) of the target substance conform to '<yellowish-brown, crystalline solid>'.

3. The substance is appropriately contained in the beaker with a suitable amount.

4. The background is a simple laboratory bench scene.

turn: 2

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 highly soluble in water, and its aqueous solution is strongly acidic. (2) It is a strong oxidizing agent and can oxidize iodide ions to iodine. (3) It is deliquescent in moist air. Which of the following substances is it most likely to be?

Options:
A. Copper(II) sulfate pentahydrate (CuSO4·5H2O)
B. Sodium chloride (NaCl)
C. Iron(III) chloride (FeCl3)
D. Potassium permanganate (KMnO4)
E. None of the above
output: answer: C

turn: 3
modality: image
input: We will subsequently refer to the substance you identified earlier as the 'target substance'. When <preparing an aqueous solution of the target substance by dissolving it in water>, the laboratory instrument <analytical balance> is used. Please generate an image depicting the correct use of this instrument in this scenario. The background is a simple laboratory bench.
output: evaluation_points: 1. The image correctly depicts the laboratory instrument <analytical balance>, and its placement on the bench is reasonable.

2. The materials and operation shown are consistent with the described scenario of '<preparing an aqueous solution of the target substance by dissolving it in water>', including a weighing boat/paper and a solid sample. The solid sample should be a yellowish-brown, crystalline solid, consistent with the appearance of the target substance described in turn 1.

3. The use of the <analytical balance> conforms to correct operational, placement, and safety standards (e.g., level, doors closed during measurement, clean).

4. The background is a simple laboratory bench scene.

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

Options:
A. It is used for precise measurement of mass, typically to the nearest 0.1 mg or 0.001 g.
B. It is acceptable to place chemical reagents directly on the weighing pan.
C. The balance should be placed on a stable, level surface away from drafts and vibrations.
D. The doors of the balance enclosure should remain open during measurement to facilitate sample handling.
E. Before use, the balance should be tared with the empty container (e.g., weighing boat) in place.
F. This instrument is primarily used for measuring the volume of liquids.
G. None of the above
output: answer: A, C, E
