input: Generate a single element tile from the periodic table for the element that satisfies the following criteria: It is a Group 2 (alkaline earth metal) element located in Period 4. The tile must 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 should generally resemble a single tile from the periodic table in form and layout.

2. The element symbol 'Ca' must be correctly centered within the tile.

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

4. The image should be clean, in a flat graphic style, containing only the single periodic table tile with no extraneous elements or background details.

input: Based on the element symbol and atomic number from the previous image, consider the following: If this element can combine with the carbonate ion (CO3^2-) to form a compound, and this compound has the properties of being a white, odorless, insoluble solid in water that reacts with dilute acids to produce carbon dioxide gas, what is the most likely compound formed?

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

turn: 3

input: We will now refer to the substance you identified in the previous question as the 'target substance'. In an experiment where the target substance reacts with dilute hydrochloric acid to produce a gas, an instrument called a gas collection apparatus (using the downward displacement of water method) is required. Please generate an image depicting the correct setup for using this apparatus during this reaction. The background should be a simple laboratory bench.
output: evaluation_points: 1. The image must correctly depict a gas collection apparatus setup for the downward displacement of water, including components like a gas delivery tube, a water-filled trough, and an inverted gas jar/measuring cylinder. The apparatus should be positioned logically on the bench.

The reaction setup should be consistent with the described reaction: a solid (representing the target substance, which is Calcium Carbonate (CaCO3)) in a conical flask or test tube, with a delivery tube leading from it into the gas collection apparatus, implying the reaction with an acid to produce a gas.

3. The use of the gas collection apparatus must conform to standard laboratory practice and safety: the delivery tube should be correctly inserted into the mouth of the inverted jar/cylinder, which is filled with water and submerged in the trough; the setup should allow for the collection of a gas that is not highly soluble in water.

4. The background must be a simple, uncluttered laboratory bench scene.

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

Options:
A. This method is suitable for collecting gases that are denser than air.
B. This method is suitable for collecting gases that are highly soluble in water.
C. Before collecting the gas, the collection jar must be completely filled with water and inverted without introducing air bubbles.
D. The gas delivery tube should be inserted into the mouth of the collection jar after gas evolution has begun to ensure purity.
E. This setup can also be used to measure the approximate volume of the gas produced.
F. The collected gas jar can be removed from the water and sealed with a glass plate while still submerged.
G. None of the above are correct.
output: answer: C, E, F
