Gas laws

Aim: To use a neutralization reaction to propel a model rocket. Hypothesis: That the neutralization reaction between the bicarbonate of soda and the vinegar will produce a gas, which build up enough pressure to launch the bottle rocket. Materials: Vinegar, bicarbonate of soda (NaHCO3) Equipment: Plastic Bottle, Wooden Block, Nail, Cork, Duct Tape. Method: 1. Nailed a cork to plank of wood as a base for the rocket. 2. Wrapped tape around cork so that it fitted the neck of the bottle. 3. Put two…

Prepare a chart for recording any observations as you test for the presence of cations in the solution. Set up and label 10 test tubes #1- #10 and place them in order in a test-tube rack. Wash and rinse all of glassware with distilled water. Prepare a hot-water bath in a 250 mL beaker by filling it up to 150 ml and bringing it to a boil. Obtain 2 ml of the solution you want to test and pour it into test tube 1. To test the solution for Pb2+ and Ag+ ions, add 8 drops of 6 M HCl solution to…

Experiment #3 (Gas) a). My first hypothesis was correct. I had a hypothesis of the glove inflating when the flask was put in the hot water because I knew that gasses with more thermal energy tend to go upwards and I assumed that the heat would make the gas particles inside the bottle expand and inflate the glove when there is no more space in the bottle My second hypothesis was also correct. I had a hypothesis of the glove deflating when the flask was put in ice because I knew that when…

By using the techniques of simple distillation and gas chromatography to purify and determine relative proportions of volatile compounds in their gas form. Distillation could be described as a process where a mixture was heated until it began to boil, and the condensed vapor was collected. After completing the distillation process, the gas chromatography method could be used to identify the relative components of a compound in a volatile mixture. According to the analysis between the…

Chemistry Internal Assessment Introduction: The experiment is to conclude which aqueous solution of the chlorides has the highest boiling point out of the five that has been tested.there will be five different chloride compounds mixed into water and be heated till it is boiling. The interest for this topic comes from how intermolecular forces affect the molecules by either repulsing and attracting molecules due to polarity. This idea interests me because when cooking and boiling salt water,…

Pure water boils at 212˚ Fahrenheit (100˚ Celsius) at sea level, but water can also boil at temperatures as low as -90˚ Fahrenheit (theoretically). The reason for this phenomenon is pressure. “There is a direct correlation between pressure and temperature when it is dealing with the boiling point of water,” says Jacob Young, a mechanical designer at Blauch Brothers, Inc (Young, J.C. 2017). The pressure on Earth at sea level is 14.696 PSIA (Pounds per Square Inch Absolute). This pressure is…

surfactants available commercially. The types of surfactants used in preparation of aqueous foam influence the foam properties (Eisner et al., 2007; Bhakta and Ruckenstein, 1995). Successful foam requires the formation, growth and stabilization of the gas bubbles in the reacting medium. The bubbles in foam can be more or less homogeneous and vary in size. The shape of bubble of the foam may be almost spherical to irregular polyhedral, based on the way in which the foam is generated and the…

The Noble Gas Equations By: Andy Jiang There is a pattern in the atomic numbers of Noble Gasses. The atomic of Noble Gasses aren't arbitrary or random. They have beautiful equations, which I have derived, that gives the atomic number of a Noble Gas based on what period it is in. Theoretically, my equations can work beyond the 7th period. The fact that there is an underlying pattern among the atomic number of Noble Gasses, something seemingly arbitrary, is a property of our mathematical,…

social tendency can influence significantly on how the company operates and the demand for the products in this industry. For example, there are increasing awareness on more friendly fuels such as natural gas and reducing in the usage of “dirty” fossil fuels such as coal, oil sands, and shale gas. Besides, the cost of labour will increase due to less-willing and smaller workforce caused by the ageing population (Bargorett & Williams, 2014). Different management strategies are used such as hiring…

This happens by drilling and injecting fluid into the ground at a high pressure to fracture shale rocks, which in turn lets out the natural gas. One of the major problems with this is when the fracking fluid, contains over six hundred different chemicals. Chemicals such as, Mercury, formaldehyde and lead to name a few. In the America today there are some 500,000 gas wells, but they need to use eight million gallons of water for each frack that happens, each well can only have eighteen fracks.…
