History, Hazards and Benefits of LPG. CNG and Gas Alternative energy such as CNG and LNG is an exciting alternative fuel that will enable society to produce a cleaner, safer and inexpensive compared to our established fossil fuels that we use today (liquefied). The uses of these gases we enjoy today has a long history, and extremely perplexing to humankind. There are precautions that must be adhered to concerning storage, use of LPG and CNG. In addition, the risks of using LPG and CNG far out…

Name: Ben Tanke, Brooke Binkley, and Hailey Fenn Block: 3rd Title: Gunpowder QPOEE Question: Which amount of Sulfur(.25 grams, .5 grams, .75 grams, and 1 gram) creates the closest reaction with fire as the store bought gunpowder in terms of size of flame and the time duration of the flame? Knowledge Probe: The equation for the reaction of our gunpowder is 10Na NO3 + 8C + 3S → 2 Na2 CO3 + 3Na2SO4 + 6CO2 + 5N2. This shows that Sodium Nitrate is reacting with…

Obtain a piece of paper that is approximately 5cm x 10cm, and tear it into small fragments. Place the pieces of paper on a watch glass, and light the paper with a match. Observe and record reactions. Deposit a microspatula of NaCL (sodium chloride) into a test tube, and dilute the substance by infiltrating approximately an inch of water to the test tube. Let the NaCL dissolve into the water by shaking the test tube with one’s thumb over the opening of the test tube. Using a dropper, place…

Light the Bunsen Burner and then use the tongs to put the magnesium ribbon into the flame. Do not look at the ignited flame because the intensity of the flame could burn the retina in the eyes. Then you pull the magnesium ribbon out of the flame. 2 Mg(s) + O2(g) = 2MgO(s)…

If heating magnesium in the presence of oxygen and they react completely, then the ionic compound’s empirical formula can be found using this equation by calculating the masses of magnesium and oxygen in this equation: Mg + O2 → MgxOy Since an ionic compound is the hopeful result of this lab, an ionic compound is a chemical compound comprising ions, which ions are an atom or molecule with a net electric charge due to the loss or gain of an electron. Ions can be negatively charged and called…

decomposition & stoichiometry. After getting the necessary supplies for the lab, get the crucible and weigh it on the scale. After that, reset the scale so that it shows all zeros. Then put a certain amount (10,00 g), set up the ring stand and bunsen burner, so you can heat the crucible and baking soda effectively. The lab procedure and data supports the hypothesis, that if baking soda is heated, then it will decompose into 2NaCO3 → Na2CO3 + CO2 + H2O. Doing the experiment, our experimental…

bottom while the clear liquid sat on top. Al2(SO4)3(aq)+3Ba(NO3)2(aq)--> 2Al(NO3)3(aq)+3BaSO4 (s) 2 First we felt the material of a piece of Magnesium. It felt maliable and smooth. We also worked with a Bunsen burner, spark lighter, and tongs. One person in our group turned on the bunsen burner, while the other took the Magnesium and held it over the fire. After a few seconds the magnesium began to react…

Background : Stoichiometry is the relationship between the relative quantities of substances taking part in a reaction or forming a compound, typically a ratio of whole integers. In the lab that I did with my group we used stoichiometry to find out the decomposition of sodium biocarbonate. Sodium carbonate is just another name for baking soda, and that is what we used on our lab. Baking soda is also used in some food items, such as pancakes, waffles etc… When the baking soda is being heated…

Purpose The purpose of the experiment that the students are conducting is to determine the empirical formula of the copper chloride hydrate by the data that has been collected throughout and that will allow the students to “investigate the effect of heating a hydrate salt” (Sanders). This will be achievable after finding the masses of chlorine, copper, and water. Introduction In this experiment, the students are using the law of multiple proportions to find the chemical formula for the compound…

In this lab we took a dull penny from before the year 1970 and changed its color to a shiny gold with the help of chemistry. First, we used a vinegar and salt mixture and scrubbed it onto the penny. This process cleaned all of the dark corrosion spots away and made the copper color shine like new, which then allowed us to have a clean surface to experiment on. This was mostly a physical change but their was a slight chemical reaction because of the acidity of the vinegar. We then heated granular…
