Experiment 7: Percentage Composition of Kclo3- A Gas law Experiment Anna CunananProfessor Stewart Chemistry 400 T/TH 1:30 PM 18 March‚ 2014 Objectives: In this Experiment‚ we will be decomposing KClO3 into two different compounds‚ KCl and O2. We are given a known mixture that has MnO2 in it to act as a catalyst. When decomposing KClO3 it releases O2 gas‚ which we then collect into the Erlenmeyer flask. The gas then displaces the water into the beaker‚ which we can then calculate the water evolved

Introduction A lava lamp (or Astro lamp) is a decorative novelty item‚ invented by British accountant Edward Craven-Walker in 1963. The lamp contains blobs of colored wax inside a glass vessel filled with clear liquid; the wax rises and falls as its density changes due to heating from an incandescent light bulb underneath the vessel. The appearance of the wax is suggestive of pāhoehoe lava‚ hence the name. The lamps are designed in a variety of styles and colours. The underlying fluid mechanics phenomenon

recognized as a significant factor of the world’s manufacturing sector. As this is so‚ there is a global demand for this commodity. Ship being the suitable mode of transportation for this commodity‚ it has being categorized among the group of major bulk cargo. Coal has a stowage factor that varies between 1.00 and 1.40 cubic metres per tonne. Being that coal is of global importance the production of the commodity has to be extensive hence the massive production centres such as; Australia‚ Russian

Abstract The objective of this experiment is to measure the force generated by impact of the jet on vanes of various shapes like flat plate‚ conical cup and hemispherical cup. Besides that‚ the results from the experiment have to be compared with the theoretical calculations too. 1.0 Introduction Water turbines are widely used throughout the world to generate power. By allowing fluid under pressure to strike the vanes of a turbine wheel‚ mechanical work can be produced. Rotational motion is

of our ship to be by multiplying the length by the width by the height which gave us a volume of 85 cm3 We then calculated the predicted number of pennies it would take to sink our ship by taking the volume of our ship and multiplying it by the density of water using the following formulas and then dividing that result by the weight of a penny (2.5g) which we rounded to 37 pennies. After we had our prediction of how many pennies it would take to sink our ship‚ we placed the ship into a container

Carriers March 23‚ 2011 Executive Summary Industry Overview Capesize dry bulk carriers provide shipping services worldwide. Due to their size‚ Capesize carriers must sail around Cape Horn in order to travel between the Atlantic and Pacifica Oceans – the ships are too large to utilize the Panama Canal. In January 2001‚ there were 553 capesize vessels in service throughout the world. Demand for dry bulk carriers is determined by the world economy. Over 85% of the capesize vessels are

Evaluate which measurement method is better for different uses. 2. Techniques Buret use: Put the buret in a buret stand and approximately fill it with temperature-equilibrated water. Make sure that the tip of the buret is filled with water and that there are no air bubbles remaining in the buret tip or valve. Record the initial level – it does not need to

boats float? All boats float‚ but floating is harder and confusing than it sounds and its best explained through a scientific concept called buoyancy. Buoyancy is the force that causes floating. An object will either float or sink depending on its density in the water. If it’s denser than water‚ it mostly sinks; the less dense object usually will float. It doesn’t matter the size of the object is. Plastic that is big as a football field will float because it is less dense that the water. A boat mostly

for milk from the dairy farm to the customer has five or six links. First‚ small dairy farmers‚ typically owners of one or two cows‚ deliver milk to the local collection point often located at the village itself. From here it is transported to a Bulk Milk Cooling centre‚ which is the first point of refrigeration. Next the milk is transported to a processing plant. Processing plants are usually located on the outskirts of towns and cities. A large metro like Chennai has two‚ catering to the northern
