Final answer:
SC stands for simple cubic lattice, each atom touches six other atoms, and there is one whole atom per simple cubic unit cell. The SI unit for amount of a substance is the mol, and the Latin name for potassium is Kalium. There are 22 hydrogen atoms in one molecule of the compound C12H22O11.
Step-by-step explanation:
The term SC can refer to simple cubic lattice structures in the context of chemistry and crystallography. In a simple cubic lattice, each cornerstone atom is shared equally among eight unit cells, so each unit cell effectively contains 1/8 of each of the eight cornerstone atoms. Thus, each simple cubic lattice unit cell contains just one atom in total.
Considering that the simple cubic lattice consists of atoms at each corner, and each of these atoms is touching the adjacent atoms in the lattice, each atom touches six other atoms in a simple cubic structure. This is due to one atom being positioned at each face of the cube's central atom, resulting in the coordination number six.
The answer to another question provided is that the SI unit for the amount of substance is the mol. The representative particle for an element is the atom, while for ionic compounds it's the formula unit. For molecular compounds, the representative particle is the molecule.
Lastly, as additional information unrelated to the main question but provided in the SEO request, the Latin name for potassium is Kalium, and there are 22 hydrogen atoms in one molecule of the compound C12H22O11.
