has an effect o the rate of a chemical reaction. In chemistry we describe concentration in terms of the number of moles of a substance there are in every cubic decimetre (litre) of solution‚ written as moles.dm-3 of M for short. • In this experiment you will find out how increasing the concentration of the acid solution changes the rate of the reaction between dilute hydrochloric acid and magnesium metal. • As the metal reacts with the acid‚ hydrogen gas is produced and the metal dissolves

timing signals has become more and more difficult. Present-day transistors can process data so quickly that they can accomplish several steps in the time that it takes a wire to carry a signal from one side of the chip to the other. Keeping the rhythm identical in all parts of a large chip requires careful design and a great deal of electrical power. Wouldn ’t it be nice to have an alternative? Clock less approach‚ which uses a technique known as asynchronous logic‚ differs from conventional

nitrate into the test tube. Add 5 to 10 drops of potassium iodide solution to the test tube and record your observations of the reaction. Pb(NO3)2 + 2 KI = 2 KNO3 + PbI2 2. Magnesium metal and hydrochloric acid solution Place one scoop of magnesium turnings into the test tube. Add hydrochloric acid slowly and observe the reaction. Next‚ place a burning splint near the mouth of the test tube to test for the presence of hydrogen gas. We notice one of the products is lead iodide which is insoluble

Global Variations in the Potato Crisps and Potato Chips Market It’s fair to assume that consumer snacking habits are likely to differ from country to country‚ particularly across different regions and cultures. A clear example is the consumption of potato crisps / potato chips which can be seen in the bar chart below. 86% of consumers throughout the USA and France consume potato crisps / potato chips closely followed by 84% of GB consumers. On the other end of the scale is the Chinese market

For over 150 years the marbles of Greece have been placed in the British museum‚ they are recognized as the Elgin Marbles. The Elgin Marbles continue to be the main point of an ongoing debate that will basically determine the historical influence of an important culture. Some of the sculptures that were removed were the marble figures‚ metopes (sculptures in high relief) and friezes. To this day the Greek government has correctly requested the return of the Elgin Marbles a few times while the British
