Analysis of a Metal Carbonate Lab Objective: In this lab we will determine the identity of a group 1 metal carbonate compound by gravimetric analysis. The unknown is weighed and dissolved in water and the precipitate is filtered‚ dried‚ and weighed. From the data the formula weight and identity of the unknown metal carbonate is determined. Lab Procedure: 1. Set up the Bunsen burner and ring clamp‚ light the burner and heat the crucible. 2. Add 2g of unknown carbonate to the crucible and

If the government doesn’t think it’s a violation‚ what would people do if they did want privacy? In this paper‚ I will argue that using a thermal imager is breaking DLK’s Fourth Amendment rights because there had been a precedent cases where the government had gone too far‚ using new technology invades privacy

Lithium Carbonate and Bipolar Disorder Lithium is a naturally occurring element that is refined to treat certain psychiatric disorders like bipolar disorder. Lithium is a naturally formed element‚ and can be found in many foods. The element has various forms such as lithium carbonate‚ lithium orotate‚ and lithium aspartate (“The Science and Practice”). The differences in lithium lie within the effects of salt on molecular weight‚ and the percentage of lithium. Lithium carbonate specifically is used

An investigation to compare the reaction rates between potato and hydrogen peroxide against liver and hydrogen peroxide through loss in mass. Background information: Catalase is an enzyme that is found in all cells. This means that it is an intracellular enzyme. And enzyme is a biological catalyst. A catalyst is some thing that speeds up a reaction without being changed itself. Because of this enzymes and catalysts can be used again and again. Enzymes are protein chains that have a primary‚ secondary

That is where hydrogen fuel cells come into the picture. Rather than depending on a foreign countries oil‚ to provide fuel‚ businesses today should look to hydrogen as an alternative fuel source. The United States is too dependent on foreign oil. If something were to happen‚ like another war with the Middle East‚ we would not have any oil to power our cars or heat our homes. That’s why hydrogen is the answer. Everybody could make their own fuel for their country by creating hydrogen plants and buying

Even though currently engineers are concentrating on producing hydrogen from natural gas‚ it will be for a short-term. Scientists are planning to have renewable environmentally-friendly ways of producing hydrogen in the future. Efficiency: Fuel cells generate electrical power quietly and efficiently. Approximate

Sodium is an electrolyte that controls the fluids in the body’s tissues and cells. It is also responsible for regulating blood pressure and volume‚ helping transmit impulses‚ and regulating the balance of blood and body fluids. I believe it is important to monitor your sodium intake in order to stay in good health. Kidneys are the most common concern when too much sodium is being taken in because it can lead to damage to the heart. When there is an excessive amount‚ the kidneys are unable to

When using glassware in experiments‚ it must be flushed out to make sure that cross contamination does not happen and that the only thing that would then be coating the beaker is the distilled water. When all of the glassware has been cleaned‚ some sodium hydroxide should be placed in a plastic weighing boat next to the scales and place the second weighing boat on the scales and weigh it then click the on tare button to set it back to zero and weigh out 1g of sodium hydroxide
