AbstractThe rates of reaction of Alkali metals and Alkaline Earth meatals are compared in this lab. The pH of each of the resulting metal solutions are tested and the products of the reaction between calcium and water is discovered. The tested elements are sodium‚ lithium‚ potassium and calcium and each of them were placed in a beaker filled with water. The resulting solutions pH levels were tested with litmus paper. There were more steps for caclium because it is the only Alkaline Earth metal. For

To begin the experiment‚ the reaction apparatus was assembled (as shown in Figure 1 below from the lab manual) consisting of a 3.0 mL conical vial charged with p-cresol (80uL from Eppendorf pipette)‚ 25% aqueous NaOH (130uL)‚ and a spin vane. The solution was mixed thoroughly and tetrabutylammonium bromide (9mg) was added along with n-propyl iodide (75uL) and it was equipped with a flask with a water reflux condenser. The solution was heated (95-100°C) while vigorously stirring it. After 60 minutes

setting of official interest rates in the United Kingdom. They set interest rates with the aim of keeping inflation under control over the next two years. Monetary policy can control the growth of demand through an increase in interest rates and a contraction in the real money supply. The effects of higher interest rates Higher interest rates reduce aggregate demand in three main ways; Discouraging borrowing by both households and companies Increasing the rate of saving (the opportunity cost

PEREGRINO‚ Marianne ECON103 MK2A REACTION PAPER UNEMPLOYMENT IN THE PHILIPPINES According to Philstar.com‚ unemployment rate in the Philippines rose to 7.5 percent in April from last year’s 6.9 percent. The National Economic and Development Authority (NEDA) said the country’s unemployment rate increased by 0.6 percent due to a lower level of employment amid a slightly higher labor force level. Majority of the unemployed were high school graduates (31.7 percent)‚ college graduates (21

The Rate of a Reaction Chemical Kinetics is the area of Chemistry that is concerned with the speed‚ rate or mechanism at which a chemical reaction occurs. Reaction Rate is the change in the concentration of a reactant or product with time (i.e. M/s). It measures how fast a reactant is consumed and how fast a product is formed. 1.2 WRITING RATE EXPRESSIONS Consider the following hypothetical reaction. A + 2B ( 3C + D Rate = - rate of consumption of A = -[pic]rate of

Possible foreign exchange risk In order to have a comprehensive view regarding foreign exchange risk‚ this part will define as well as separate this exposure into clearer and smaller concepts. Firstly‚ it is highlighted to indicate that foreign exchange exposure possibly occurs as a result of the fluctuation of exchange rates‚ leading to negative effects on profitability‚ cash flows and other financial indicators

Effect of osmosis rate on different surface areas‚ depending on different types of water solution An investigation showing the effect of surface area on osmosis rate‚ including some different types of water concentration. Osmosis is a type of passive (not requiring energy) transport of water molecules across partially permeable membrane‚ from an area of high water concentration into area of low water concentration. But how does surface area affect rate of osmosis? Surface area plays important
