They get a big block of it and put it to a grinder. Its atomic number is 58 and its chemical symbol is Ce. The last element I will discuss is neodymium. It is the best known out of the lanthanide series out of rare earths because of the one and only neodymium magnets. They are the strongest magnets in the world and there are many purposes

Natural disasters and human emergencies are recurring phenomenon’s that leave disastrous effects in their wake. On 12th January 2010‚ a major earthquake of a 7.0 magnitude on the Richter scale hit Haiti. The catastrophic quake centred about 15 miles South West of Port-au-Prince left considerable damage to a majority of towns in the country including the capital city. According to UN reports‚ of the total 9 million people in the country‚ the earthquake has affected half of the population. About 222

Chemical Bonding Chemical compounds are formed by the joining of two or more atoms. A stable compound occurs when the total energy of the combination has lower energy than the separated atoms. The bound state implies a net attractive force between the atoms ... a chemical bond. The two extreme cases of chemical bonds are: Covalent bond: bond in which one or more pairs of electrons are shared by two atoms. Ionic bond: bond in which one or more electrons from one atom are removed and attached to

Natural Hazards and Natural Disasters A natural hazard is a threat of a naturally occurring event will have a negative effect on humans. This negative effect is what we call a natural disaster. In other words when the hazardous threat actually happens and harms humans‚ we call the event a natural disaster. Natural Hazards (and the resulting disasters) are the result of naturally occurring processes that have operated throughout Earth’s history. Effects of Hazards Hazardous process of all

The decision making of multiple employees and managers contributed to the Deepwater Horizon disaster. A non-rational model of decision making was utilized which directly contributed to the malfunction of equipment and the death of employees. The non-rational model attempts to explain how decisions are actually made (Kanicki & Kreitz‚ 2010). The case study focuses on how decisions are actually made rather than how they should have been. Decisions made regarding safety‚ process‚ and collaboration

Chemical Proportionality (Carbonate and Hydrochloric Acid) Introduction: The purpose of this experiment is what happens when a solid substance‚ a metal carbonate is added slowly to a solution of an acid. We are finding methods of determining acid concentration. For us to balance certain equations‚ we will use a stoichiometry. For this experiment‚ we will need to set up the ratio and finding the concentration of HCI. Procedure: • Grab 4 different beakers. • Add a small amount of sodium carbonate
