The ideal gas law is shown as PV=nRt, where R is considered the gas constant in the equation or the problem that is being asked in a question. Solutions 5.What factors affect the rate at which a solution dissolves? When you heat or cool the solution it will increase when heated and decrease when cooled, also you can break the pieces of the solvent into smaller pieces and it will dissolve faster. As well as adding solvent will decrease the rate of dissolving.…

Experiment 4: Kinetics of Nucleophilic Substitutions 1. Determine the effect of varying [OH-] on the rate of the reaction. To do this, you should complete the following table: Experiment [tBuCl]0 (M) [OH-]0 (M ) Time (s) Reaction rate (M/s) Rate constant (s-1) 1 0.03 0.003 65 4.89 · 10-5 1.62 · 10-3 2 0.03 0.006 213 3.15 · 10-5 1.05 · 10-3 3 0.03 0.009 362 2.96 · 10-5 9.85 · 10-4 What is the dependence of [OH-] on the rate law? The effect of the increased or decreased [OH-] on the rate law is very minimal.…
In general, viatical settlements are ethical. In the case of a viatical settlement, it is simply an exchange of cash today for payment in the future, although the payment depends on the death of the seller. The purchaser of the life insurance policy is bearing the risk that the insured individual will live longer than expected. Although viatical settlements are ethical, they may not be the best choice for an individual. In a Business Week article (October 31, 2005), options were examined for a 72 year old male with a life expectancy of 8 years and a $1 million dollar life insurance policy with an annual premium of $37,000.…
I. Science fair question How does temperature affect the rate at which UV beads lose their color? II. Background Research Did you know that most of the ultraviolet light produced by the Sun is blocked by the atmosphere, but some light does still reach Earth? Ultra violet light can be detected using electronic devices. Important terms that will be discussed in this paper are ultraviolet light, photochromism, chemical reactions, and absolute zero.…
Purpose: Measuring ‘g’ by dropping steel ball and Ping-Pong ball from the same height and record the time for each dropping. Then, using the equation “h=1/2g*t^2 to calculate ‘g’. For precise, we still need to find ∆g, therefore, the final data about g=gave+∆g. Method: Before we start to do the experiment, we need to find a position which can except the wind and flat ground.…
• The temperature in the room may have altered. A dependent variable is a variable you do not change during an experiment. Instead, it changes as a result of other changes you make.…
In this equation mass refers to the mass of the bottle (including water) and force refers to the drag force exerted by the expelling of water. As there is constant removal water the mass will be decreasing which affects the acceleration. If looked at mathematically, if the drag force is constant and is constantly divided by the mass which is declining the acceleration will escalate. Acceleration will continue until the water is finished and there is no mass or drag force. NEWTONS LAW THREE APPPLIED TO WATER ROCKETS…
DISCUSSION OF RESULTS: Answer the following Questions: 1. How did changing the angle of the slope affect the acceleration of the object? Use information from the summary table and/or graph. According to our data, the larger that the slope was, the faster the acceleration of the object was.…
Cecilia Wong Nature of the task and the research question: Two centimetre piece of potato is bathes into different salt solutions (0%, 5%, 10%, 15%, 25%, 35%) over a period of time, to determine the effect of different salt solutions on osmosis.

INTROUCTION Asset liability management: It is the management of assets and liabilities in such a way that the net earnings from interest is maximized and minimizing the overall risk associated with it. So it is a tool that helps bank to take business decisions in a known window with the view of the risk that the bank is associated with. Portfolio management: Portfolio is a combination of financial instruments like bonds, common stocks, banknotes, debentures and other instruments. The process of obtaining optimum returns with minimum risk from the combination of various portfolios is called portfolio management. Immunization is a strategy that equalize the duration of assets and liabilities such that it minimizes the impact of interest rates…
“P1” stands for pressure energy (pressure in the fluid), “ρ” is the density, “v” is the velocity of the fluid, “g” stands for the acceleration due to gravity (9.8 or 10, whichever you prefer), and “h” equals the height of fluid off the ground (“Bernoulli’s Equation”). Let us do an example problem to help put this into perspective: “Say that an amount water flows through an ‘s’ shaped pipe. At one end of the pipe, the water has a pressure of 160,000 Pascal (Pa), a velocity of 7.0 m/s, and has a height of 1.2 m. At the other end of the pipe, the velocity of the water increased to 11 m/s, and the height has raised to 4.0 m. The density of the water is 2000 kg/m^3” (Friedl). Now, all you have to do is the plug the information into the equation: ρ = 2000 kg/m^3, g = 9.8 m/s^2, P1 = 160,000 Pa, v1 = 7.0 m/s, h1 = 1 m, v2 = 11 m/s, h2 = 4.0 m, and P2 is…?…
