... living things are molecules. A molecule is a neutral group of atoms that are held together by covalent bonds. A molecule formed by polar-covalent bonds is still considered neutral because the sum of the partial charges on either end of the bond is zero. A molecular compound is any chemical compound ...

... The crystal field diagrams are different because the geometries of where the ligands point is different. The tetrahedrally oriented ligands point differently in relationship to the d-orbitals than do the octahedrally oriented ligands. Plus, we have more ligands in an octahedral complex. See Figure 2 ...

... (mod 15), 10x + 9y ≡ 8 (mod 15), the idea is (similar to the linear algebra in solving linear equations) to eliminate one variable, say y. To do so, one naturally wants to multiply 9 on the both sides of the first equation and to multiply 2 on the second equation. Let’s see what happened after we mu ...
