In addition, when sales order revenue is only partially recognized, the associated COGS is recognized in the same proportion. With this feature, sales order revenue and the associated COGS are recognized in the same period. The Oracle E-Business Suite supports this matching principle by synchronizing the recognition of cost of goods sold (COGS) with the revenue recognized in Oracle Receivables for shipments made in Oracle Order Management, or other order fulfillment systems. The matching principle requires that cash outlays associated directly with revenues are expensed in the period in which the firm recognizes the revenue. The revenue recognition principle requires revenues to be recognized when a firm has performed all, or a substantial portion of services to be provided, and cash receipt is reasonably certain.

COGS Recognition and Concurrent Processesįinancial accounting has two important Generally Accepted Accounting Principles (GAAP) that guide the statement of financial earnings:.

If there are no lone electron pairs on the central atom, the electron pair and molecular geometries are the same.Ĭlick here to see the various molecular geometries.Ĭhoose the correct molecular geometries for the following molecules or ions below.This chapter covers the following topics: Step 4: The molecular geometry describes the position only of atomic nuclei (not lone electron pairs) of a molecule (or ion).

* Lone electron pairs are represented by a line without an atom attached. The table below shows the electron pair geometries for the structures we've been looking at: The regions of electron density will arrange themselves around the central atom so that they are as far apart from each other as possible. Use this number to determine the electron pair geometry.Įach bond (whether it be a single, double or triple bond) and each lone electron pair is a region of electron density around the central atom. Step 3: Add these two numbers together to get the regions of electron density around the central atom. Make sure you understand why they are correct. The correct answers have been entered for you.

How many lone electron pairs are on the central atom in each of the following Lewis structures? Step 1: Count the number of lone electron pairs on the central atom.

Molecular geometry can be predicted using VSEPR by following a series of steps: In other words, the electrons will try to be as far apart as possible while still bonded to the central atom. The theory says that repulsion among the pairs of electrons on a central atom (whether bonding or non-bonding electron pairs) will control the geometry of the molecule. The valence shell electron-pair repulsion theory (abbreviated VSEPR) is commonly used to predict molecular geometry. Lewis structures are very useful in predicting the geometry of a molecule or ion. Many of the physical and chemical properties of a molecule or ion are determined by its three-dimensional shape (or molecular geometry).
