The Series 7 is a three-hour, forty-five-minute exam. [1] It is held in one four-hour session. There are 125 questions on the test. Candidates have to score at least 72% to pass. The SIE Exam and the Series 7 Exam are co-requisite exams. [9] Average study time is between 80 and 150 hours depending on current financial knowledge. [10]
For very low values of the ionic strength the value of the denominator in the expression above becomes nearly equal to one. In this situation the mean activity coefficient is proportional to the square root of the ionic strength. This is known as the Debye–Hückel limiting law. In this limit the equation is given as follows [14]: section 2.5.2
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
This is a list of unsolved problems in chemistry. Problems in chemistry are considered unsolved when an expert in the field considers it unsolved or when several experts in the field disagree about a solution to a problem.
Theoretical chemistry requires quantities from core physics, such as time, volume, temperature, and pressure.But the highly quantitative nature of physical chemistry, in a more specialized way than core physics, uses molar amounts of substance rather than simply counting numbers; this leads to the specialized definitions in this article.
This model corresponds, for example, to a series of nuclear decompositions like 239 U → 239 Np → 239 Pu. If the rate constants for the following reaction are k 1 and k 2; A → B → C, combining the rate equations with a mass balance for the system yields three coupled differential equations:
The CFP and Series 7 are two designations you might see in the finance industry that are held by financial advisors. However, the CFP and Series 7 are used for different purposes. A series 7 ...
For example, if equilibrium is specified by a single chemical equation:, [24] ∑ j = 0 m ν j R j = 0 {\displaystyle \sum _{j=0}^{m}\nu _{j}R_{j}=0} where ν j is the stoichiometric coefficient for the j th molecule (negative for reactants, positive for products) and R j is the symbol for the j th molecule, a properly balanced equation will obey:
