ACCOUNTING SYSTEMS Tiffany Bullock HS210-02 March 21‚ 2013 The three types of bookkeeping systems are Pegboard‚ Single Entry‚ and Double Entry. The Pegboard system is also called the write-it-once system. This system is the most widely used manual method of accounting in the healthcare industry. The cost of using this system is a little more than the others. It is a lightweight board that uses pegs to hold all the different forms in place. This system can hold forms for the daily log sheet

reaction. However‚ in a fast reaction the fraction is high and therefore‚ collisions produce a reaction. In 1889‚ Svante Arrhenius demonstrated that the rate constant k is related to the temperature of the system by what is known as the Arrhenius equation: k=A where R is the ideal gas constant [8.314 J/(mol oK)]‚ T is the temperature in degrees Kelvin‚ Ea is the activation energy in joules per mol‚ and A is a constant called the frequency factor‚ which is related to the fraction of collisions between

Rates of reaction Sodium Thiosulphate and Hydrochloric Acid An experiment was carried out to investigate the effect of temperature on the rate of reaction between sodium thiosulphate and hydrochloric acid. The equation for this reaction is shown below. Method (1) A measuring cylinder was used to measure 50cm3 of 0.08M sodium thiosulphate solution into a test tube. A bung was placed in the test tube. (2) A pipette was used to measure 5cm3 of 1.0M hydrochloric acid and this was placed into a second

Projectile motion into physics Objective: Our purpose for this lab was to observe projectile motion and use the equations of motion to predict the objects location in different instances of time. We used a projectile launcher and a ball to observe these properties of motion. The main equation used in this lab was d=Vit+1/2at^2 where Vit will produce the distance due to constant motion and 1/2at^2 will produce distance traveled due to accelerated motion or gravity in this case.
