Chemical Formula of Calcium Carbide Written on Slate Chalkboard Stock Image - Free Download

A high-resolution professional macro photograph of a calcium carbide chemical formula written on a clean, slightly textured slate chalkboard. The chemical formula 'CaC2' is written in crisp, white chalk with precise strokes. Next to the formula, a small, authentic pile of greyish-black calcium carbide lumps sits on the ledge of the chalkboard. The lighting is soft and directional, creating subtle shadows that give the lumps a realistic, rocky texture. The background is a soft-focus laboratory setting with blurred glassware and a periodic table, ensuring a shallow depth of field. No artificial glows or synthetic digital effects; natural classroom or lab aesthetic.
