Abstract Chemical equilibrium occurs when a reversible reaction is happening forward and backward‚ at the same time by the same amount‚ is equal. Two procedures were made. First is the Effect of Concentration on Equilibrium. The solution became orange when it was diluted with ammonium hydroxide and the solution became yellow when water was added to the solution. In the second‚ Effect of Temperature on Equilibrium‚ the solution turned into a light brown gas when it was placed in the refrigerator

fires and is a tool that you should carry when you go into the woods. Cerium and the element before‚ lanthanum are both used for dramatic spark effects in movies. 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

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

follow a diamond’s global path to market. Below: 1. The search for diamonds is not exactly easy. Many miners and diamond diggers in sub-Saharan Africa travel great distances to find work and submit to gruelingly long hours for low wages – or sometimes no wages – in substandard conditions. The informal mining industry is where workers tend to be most exploited. In the Wild West atmosphere of many informal diamond mines‚ the quest for the “big find” – and the financial gain it promises – is
