and society’s characteristics by which we are symbolized and recognised as to who we are. In this assignment I intend to explore the meaning of identity. In considering the link between personal and social‚ I will examine the process of identity formation‚ and discuss the extent in which we are able to control and shape our own identities. The definition of identity has been contested by many social scientists‚ as it has many influences‚ which has to be considered‚ such as‚ gender‚ social class

oxidation-reduction reaction of magnesium and hydrochloric acid solution. We compared the experimental measured amount of a product and the amount predicted by the theoretical calculation of a balanced equation: Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g) PROCEDURE First we obtained a strip of pre-cut magnesium ribbon‚ cleaned it with steel wool to remove any signs of oxidation from the strip (which would alter our results)‚ and then weighed it (individual masses of the magnesium strips for each trial can

The intent of this experiment is to demonstrate the formations of the world oceans and why they are salty. I hope to learn more about the formations of the world oceans and what causes the oceans to be salty. Based on my research‚ I know that if salty water was put on black paper and left outside in the sun‚ the water would evaporate but the salt crystals would stay. The salt would not evaporate because it is a solid. Knowing this I formed a hypothesis‚ being‚ if salty water was poured on black paper

The test tube with a side pipe was connected with a glass syringe. 3. About 3 cm of magnesium ribbon was measured out using a ruler. 4. The magnesium ribbon was polished using steel wool to remove any coating of oxides as magnesium can be a reactive metal. When magnesium is exposed to oxygen it reacts to form metal oxides. This step is necessary in order to obtain reliable results. 5. The mass of magnesium ribbon was measured and recorded using top pan balance. 6. Step 3‚ 4 and 5 was repeated

theories then another scientists proves it wrong. I believe that the moon was formed from the big impact. The first theory is the co-formation theory. The co-formation theory also know as the condensation theory‚ says that the moon was formed at the same time as the earth. The theory states that the solar system was formed out of the solar nebula. The co formation theory explains why the moon appears to be in the location it is in. The weakness of this theory is because if the moon and the earth

a) Factors leading to the formation of Malaysia in 1963 1. Only Malaya was an independent nation while Singapore‚ Brunei‚ Sabah and Sarawak were still under British control. These territories were considered too small to be independent entities. It was felt that a merger with Malaya would bring early independence to these territories. 2. The British were agreeable to a merger of these territories and granting independence as there were many similarities between Malaya‚ Singapore‚ Sabah‚

Determination of the Enthalpy for Decomposition of Hydrogen Peroxide Objective: To construct a coffee cup calorimeter‚ measure its calorimeter constant‚ and determine the enthalpy of decomposition and formation of hydrogen peroxide. Background: This experiment is a classic thermodynamics lab. In it‚ we attempt to measure the enthalpy (H) of a chemical reaction. The main obstacle is that this is a quantity that cannot be measured directly. It instead is observed as heat from one substance is transferred

authorized structure and were granted exclusive rights to trade and conduct business in certain markets and products. The fact that firms are a different way to organize economic activities cannot explain explicitly and adequately the reason of firm formation. Many socialists and economists have given their interpretations of the conditions under which firms emerged and developed in certain ways in a specialised exchange economy. These explanations are drawn from each other yet have different identified
