EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

How does Nuclear power work and what happened at Chernobyl? What would you do if your town had a nuclear power plant explosion? Would you help clean up or would you just leave town? I would help the people of my town by cleaning up. The chernobyl explosion was caused by an operator error‚ and cost a lot of money and hurt a lot of people. Nuclear power is made up of atoms that are constructed like a mini solar system. By the late 1950’s nuclear power was developed. There are two types of uranium

and cooling alone. Cutting back on these two energy uses - the computers themselves and the energy used to cool them - makes a direct impact on company costs. Cutting back on energy use by making things more efficient can bring secondary savings too‚ which may not be immediately obvious. If you can increase the energy efficiency of front and back-office computing‚ you may not need to increase hardware resources as quickly as you thought‚ which can save capital expenditure on the kit‚ cooling equipment

nuclear fuels undergo fission to release huge amounts of energy. This heat turns water to steam‚ which spins turbines to produce electricity. After cooling the used steam must be cooled and condensed back into water. To condense the steam‚ cool water is brought into the plant and circulated next to the hot steam. In this process‚ the water used for cooling increases 5 to 10 Celsius degrees. Industries such as metalworking use large amounts of water as coolant‚ and then release this water back into

different types of candy are made‚ such as chewy (fudge)‚ gritty (cotton candy)‚ or hard (glass candy). You can make fudge by continuously stirring the sugar syrup after a period of cooling‚ so when the sugar crystals form‚ they stay very small and do not grow that to be big. You can make cotton candy or glass by cooling the syrup quickly to keep the crystals from forming. The main difference between the types are whether sugar crystals are allowed to form and if they do what their size is. The

Science Neutron stars‚ second only to black holes and pints of Guinness as the densest objects in the Universe‚ may have liquid in their cores‚ observations of a dead star shrouded in the debris of a distant supernova suggest. Two separate teams of scientists say that a frictionless state of matter called a superfluid is the only reasonable explanation for temperature changes recently observed in the youngest known neutron star. “This the first direct evidence for superfluidity in neutron stars

INTRODUCTION Vapour absorption refrigeration system is one of the oldest methods of producing refrigerating effect. John Leslie in 1810 kept H2SO4 and water in two separate jars connected together. H2SO4 has very high affinity for water. It absorbs water vapour and this becomes the principle of removing the evaporated water vapour requiring no compressor or pump. H2SO4 is an absorbent in this system that has to be recycled by heating to get rid of the absorbed water vapour‚ for continuous
