HELP! URGENT Which of the following best states the relationship between erosion and deposition?

A.
When the energy transporting sediments diminishes, the sediments settle in a low-lying area; therefore, deposition always follows erosion.
B.
When the energy transporting sediments diminishes, the sediments settle in a low-lying area; therefore, erosion always follows deposition.
C.
When rock is broken down into sediments, the sediments are eventually transported to another location; therefore, deposition is a form of erosion.
D.
When rock is broken down into sediments, the sediments are eventually transported to another location; therefore, erosion is a form of deposition.

Often in organic synthesis reactions, multiple products will be synthesized that need to be separated from each other. The separatory funnel is a standard organic laboratory tool that uses differences in chemical solubility to separate compounds.

In order to be in a position to manipulate any operation, one has to know all the fine details of the system and where and how one might apply subtle changes to affect the outcome. When looking at chemical reactions, it is from the study of its kinetics that one gleams the insight necessary to be able to do this. The main use of chemical kinetics is to measure the speed of a chemical reaction. But more importantly, in measuring the speed of a reaction, one gains insight as to what part of the reaction imparts this speed (or lack thereof) and thus allows one to propose a specific mechanism that details the critical pathway for the reaction. Measuring the speed of a chemical reaction is very similar to measuring speed in general, except that instead of talking in terms of distance traveled per unit time we are measuring either reactants consumed per unit time or products produced per unit time. There are many factors that affect the speed of a chemical reaction, some of the more common ones being:

A chemical equation is balanced when the number of each
type of ____ is the same on both sides of the equation.

Maleic anhydride reacts with ethylene glycol to produce an alkyd resin. Draw thestructure of the condensation polymer produced.

A resonance structure will be insignificant if it has carbon atoms with opposite charges (C- and C ). Azulene represents an exception to this rule, because some resonance structures (with C- and C ) exhibit aromatic stabilization. Draw a resonance structure of azulene with formal charges that best explains the aromatic stabilization. Include lone pairs in your answer.
