WebAug 15, 2024 · Rules to determine oxidation states The oxidation state of an uncombined element is zero. This applies regardless of the structure of the element: Xe, Cl 2, S 8, and large structures of carbon or silicon each have an oxidation state of zero. The sum of the oxidation states of all the atoms or ions in a neutral compound is zero. WebThe ratio of radius of cation to anion is called radius ratio.

WebAn octahedron may then form with a radius ratio greater than or equal to 0.414, but as the ratio rises above 0.732, a cubic geometry becomes more stable. This explains why Na + in NaCl with a radius ratio of 0.55 has octahedral coordination, whereas Cs + in CsCl with a radius ratio of 0.93 has cubic coordination.
WebThe rate of change of the oil film is given by the derivative dA/dt, where. A = πr 2. Differentiate both sides of the area equation using the chain rule. dA/dt = d/dt (πr 2 )=2πr (dr/dt) It is given dr/dt = 1.2 meters/minute. Substitute and solve for the growing rate of the oil spot. (2πr) dr/dt = 2πr (1.2) = 2.4πr.
