Mass of Magnesium(Mg) (g) | Volume of Hydrogen (H₂) (cm³) | 1st trial | 0.040 | 39.9 | 2nd trial | 0.040 | 40.3 | 3rd trial | 0.035 | 36.5 | Quantitative data: The Magnesium was silvery-white‚ lustrous and relatively flexible before being placed in the burette. Whilst reacting with the hydrochloric acid‚ it dissolved and bubbles were visible. The hydrochloric acid slowly diffused downwards. Calculations: Volume of un-diffused hydrochloric acid = 25 cm³ Average mass of magnesium = 0.038

David Ricardo ’s theory of comparative advantage‚ Raymond Vernon ’s product life cycle‚ John Dunning ’s eclectic theory and all others are essentially explanations of business between domestic firms or regions‚ as well as international firms. They explain "multidomestic" investment and intra-national trade. Those theories offer important insights into the functioning of firms in business anywhere‚ including international firms‚ but they fail to focus on the distinguishing characteristics

Finding the formula of magnesium oxide Aims When magnesium is heated in air‚ it reacts with oxygen. During this oxidation reaction‚ magnesium oxide is produced. This increases the mass. If we know the mass of magnesium at the start‚ and the mass of magnesium oxide produced at the end‚ we can work out the mass of oxygen which has been combined with the magnesium. We can use these masses to work out the formula of magnesium oxide. Eye protection must be worn Apparatus Crucible and lid

Who are the winners and losers of globalization? Globalization is the process of international integration arising from the interchange of world views‚ products goods and services‚ ideas‚ and other aspects of culture. It is featured in nearly every country in the world and this is through mainly the trading of goods from one country to another. Globalisation can bring wealth into a country as it brings in more products or materials to be sold or to produce many more goods locally and industrially

iLab‚ Week # 3 ATOMIC WEIGHT OF MAGNESIUM LAB Introduction The purpose of this lab experiment is to determine the atomic weight of magnesium by measuring the amount of hydrogen gas evolved when hydrochloric acid reacts with magnesium. The reaction is as followed: Mg + 2HCL H2 + Mg2+(aq) + 2Cl-(aq) In this experiment there is a one to one relationship between the number of moles of hydrogen gas evolved and the moles of magnesium metal consumed in the reaction. Therefore in the finding of
