modality: image
input: It is known that the target substance is one of the correct options from the previous question and additionally satisfies the condition: 'This metal is typically stored in a sealed container to prevent the formation of a thin, protective oxide layer from excessive atmospheric exposure, though it is not stored under an inert liquid like oil.' Please generate an image showing this target substance stored correctly in its appropriate container and placed on a laboratory bench.
output: evaluation_points: 1. The container depicted is correct: a sealed glass or plastic reagent bottle or a labeled storage jar, consistent with common laboratory practice for storing stable metals.

The substance generated is indeed Aluminum metal. Its appearance should be silvery-white (though may appear slightly dulled due to a thin oxide layer) and in the form of small foil pieces, pellets, or turnings (not a fine powder, which is less common for general storage). This description is based on the properties defined in turn 1: 'A silvery-white, solid metal at room temperature, with a density less than 5 g/cm³, that reacts with dilute hydrochloric acid to produce hydrogen gas'.

3. The substance is contained within the sealed bottle/jar, not submerged in any liquid (like oil or kerosene). The amount shown should be a reasonable laboratory quantity (e.g., filling a portion of the container, not overflowing or just a single piece).

turn: 3
modality: image
input: We will subsequently refer to the substance you identified earlier as the 'target substance'. Please generate the target substance undergoing combustion in air (at ambient temperature and pressure). The background is a simple laboratory bench.
output: evaluation_points: 1. The combustion depicted should be vigorous and bright, consistent with the intense, exothermic reaction of finely divided aluminum (e.g., powder or very thin foil) in air. Bulk aluminum pieces would not combust under these conditions, so the substance form must imply high surface area.

2. The flame color should be a brilliant white or intense white-yellow, which is characteristic of aluminum combustion, often accompanied by sparks.

3. The combustion should be shown using appropriate and safe apparatus. A common method is aluminum powder being sprinkled into the flame of a Bunsen burner from a spatula or from a crucible lid held with crucible tongs. Alternatively, a small pile of powder on a non-combustible surface (like a ceramic watch glass or crucible) being ignited could be shown. The holding method (tongs, spatula) must be clear and safe.

output: evaluation_points: 1. The combustion depicted is vigorous, showing a bright, sustained flame and potentially molten droplets.

2. The flame color is a characteristic bright yellow, consistent with the emission spectrum of sodium.

3. The combustion uses appropriate instruments: the sodium metal is held securely in a crucible or on a non-reactive surface (like a ceramic tile or in a deflagrating spoon), not directly in hand. If a deflagrating spoon is used, it should be held by a clamp on a stand.

The background is a simple laboratory bench scene, consistent with the background in the image generated in turn 2.
