The Effect of the Concentration of Sulphuric Acid on the Reaction Rate with Magnesium Sarah Cain SCH 4UB Mr. Lankin April 1‚ 2009 Introduction The nature of the problem is to design an investigation that examines a variable affecting the reaction rate. In this experiment‚ magnesium will be reacted with different concentrations of sulphuric acid. The reaction is shown by the following chemical equation: H2SO4 (l) + Mg (s) → MgSO4 (aq) + H2

To manage exchange rate risk activity‚ Tiffany’s objectives should be to minimize foreign exchange rate risk and lower counterparty risks. We want to minimize these risks because Tiffany & Co. is selling goods that are denominated in US dollars‚ but sold for yen in the Japanese market. The objective of this program is to prevent the depreciation of the yen against the US dollar by hedging the currency. The expected Japanese sales of Tiffany & Co. should be actively managed by purchasing hedging contracts

certain factors of a chemical reaction affect the rate of reaction. This experiment focused on how temperature affects the rate of reaction for the reaction of alka-seltzer and water. The rate of a reaction is a value calculated to figure out how fast a chemical reaction occurs. There are three factors that can be changed that will affect the rate of a chemical reaction: surface area‚ concentration‚ and temperature. Temperature specifically affects the rate of a chemical reaction‚ because when the temperature

Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment‚ we will have to conduct another experiment‚ to see what concentration of acid we will have to use. We done this using 0.1M‚ 0.5M and 1M of Hydrochloric acid‚ and 0.1g of powdered limestone‚ we used powdered limestone‚ as it would be a fairer test‚ I think this as all the particles of limestone will

graph show that there is a strong positive correlation between the average rate of conductivity and the surface area: volume ratio. As the surface area of the Agar cube increases‚ the rate of conductivity will steadily increase‚ too. The trend line of the graph shows as an exponential graph because at one point there will be no more conductivity due to too small or too big Agar cubes. A difference can be seen in the average rate of conductivity depending on surface area because the Agar cubes with a

or increased in number‚ the reaction will increase in rate because faster collisions will take place making more successful collisions. This diagram shows five solutions hydrochloric acid and magnesium ribbon that are reacting. The arrows represent a simplified way to show how many successful collisions occur each second; therefore the more arrows there are‚ the faster the rate of reaction. They show how different factors can affect the rate of reaction against these two reactants (magnesium and

The Therapeutic Frame Introduction to the Therapeutic Frame The therapeutic frame refers to the fundamental guidelines within which psychotherapy is conducted. Psychodynamic therapists are especially concerned with formulating the therapeutic frame to create a predictable and safe psychological and physical space for conducting therapy (Howard‚ 2009). It is imperative to have this space in counselling as it has been proven to optimise the conditions for the client to come to touch with his/her
