Pluto: A Planet? Many issues have arisen from the debate whether or not Pluto is a planet. Some astronomers say that Pluto should be classified as a "minor planet" due to its size‚ physical characteristics‚ and other factors. On the other hand‚ some astronomers defend Pluto’s planet status‚ citing several key features. Indeed‚ most of the problem is that there is no formal definition of a planet. Furthermore‚ it is very difficult to invent one that would allow the solar system to contain all

It passes across the optic nerve (CN II) and runs obliquely beneath the superior rectus muscle and superior oblique muscle to the medial wall of the orbital cavity. After giving the posterior ethmoidal nerve and anterior ethmoidal nerve‚ it terminates as the infratrochlear nerve on the medial margin of the orbit. Branches The nasociliary nerve gives off the following branches: • posterior ethmoidal

QUIZ LP Formulation 1. ACME Co. is a manufacturer of X’s which they sell to OR/MS teachers to be used as variables. For this week they intend to manufacture two types of X’s‚ namely‚ X1’s & X2’s. The profit contribution for each unit of X1 & X2 are $4 and $5‚ respectively. Mr. Loony‚ the manager of ACME‚ found out that his available supply of raw material 1 (RM1) and raw material 2 (RM2) are 18 units and 24‚ respectively. Each unit of X1 will require 3 units of RM1 and 3 units of RM2 while

This molecular orbital model can be used to explain why He2 molecules don’t exist. Combining a pair of helium atoms with 1s2 electron configurations would produce a molecule with a pair of electrons in both the bonding and the * antibonding molecular orbitals. The total energy of an He2 molecule would be essentially the same as the energy of a pair of isolated helium atoms‚ and there would be nothing to hold the helium atoms together to form a molecule. The fact that an He2 molecule is neither

Rules for aromaticity 1. A cyclic planer structure and each atom must have a P orbital so that the electron cloud is not intterupted 2. It must contain an odd number of electron pairs ▪ i.e. the number of electrons must be 4n+2 where n=0‚1‚2‚3‚4……… ▪ so the number of electrons is 2‚6‚10‚14‚18……. ▪ this rule is called the Hückel’s Rule • monocyclic hydrocarbons with alternating single and double bonds are called annulenes • annulenes are named as [n]-annulene
