increased chance of collisions between reactant particles. Since the collisions become more frequent and abundant‚ the rate of reaction increases. Aim The aim of the experiment is to see if a greater surface area of a dissolvable tablet creates a faster or slower reaction Independent Variable The surface area of the tablet (halves‚ powdered and whole) Dependent Variable How fast the rate of reaction is to the surface area Controlled Variables The amount of water (250mL) The type of dissolvable

the production of Adenosine Triphosphate (ATP)‚ which gives them the energy they need to perform. In this experiment‚ creatine is added to water and its effects on Daphnia is tested. By observing the heart rate‚ one can determine if the creatine increases or decreases heart rate. Heart rate was chosen to be measured because one can then see how creatine affects the heart. If it is unhealthy for the Daphnia‚ it could potentially be unhealthy for humans. “Long-term safety of creatine supplementation

3 Factors that Influence Rate of Return Any bondholder‚ or any investor for that matter‚ will allow three factors to influence his or her required rate of return. The three factors are the following: real (pure) rate of return‚ inflation‚ and risk premium. These three factors equal the risk free rate which is the rate of return of an investment with no risk of financial loss. This is also the rate that investors would expect from an absolutely risk-free investment over a period of time.

Interest Rate Risk in Islamic Banking Introduction Many countries‚ especially those with a substantial number of Muslim citizens operate a dual banking system. This system has both the Islamic and conventional banking systems which cater for the needs of both the Muslim bankers and the non-Muslim bankers. In a conventional and theoretical banking system‚ it would be expected that a change in the banking interest rates would yield a responsorial change for customers in the event that the customers

thought that the reaction ends when it runs out of A and B it actually does not. In most reactions C and D start to react to form A and B at a certain point as you can see in the equation c C + d D → a A + b B. These two reactions occur until the rate of reaction in both equations become equal (meaning the speed of the production of C and D in the first equation is equal to the speed of the production of A and B in the second equation) resulting in a

Caffeine effect on Daphnia’s heart rate Prepared for: Androniki Kloni By: Maria Mitsi October 6‚ 2013 Abstract Caffeine is a bitter‚ white crystalline xanthine alkaloid and a stimulant drug. Caffeine is found in varying quantities in the seeds‚ leaves‚ and fruit of some plants‚ where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants‚ as well as enhancing the reward memory of pollinators. An experiment was held‚ on an aquatic

The reaction order‚ based on the rate law‚ was first order with respect to crystal violet and second order with respect to OH-. The rate law was as follows: Rate law = k [CV]1[OH-]1 where k equaled 2.61. In order to determine the reaction order with respect to crystal violet‚ the graph that described the relationship between ln[CV] and time (seconds) was Figure 2. Not only did Figure 2 generate a more linear relationship‚ but it had the highest R2 value of 0.992 than ([CV] versus time) and ([1/CV]
