Ethylene glycol is mixed with water so it is 50% of each liquid in the solution and has the highest boiling point than any other radiator fluid (5); its boiling point is 197.3°C and has a melting point of -12.9°C (12). This makes it a good heat transfer fluid because having a low melting point will mean that it can flow in colder conditions and have a high boiling point means it can be used in the summer (13). It is also odourless and colourless (6) and has a specific heat capacity (SHC) of 2.2 J/g/°C (9). Propylene glycol is mixed with water (70% fluid, 30% water) and it prevents corrosion (5). It is quite like ethylene glycol.
2NaCl + H2SO4 —> Na2SO4 + 2HCl 4. If 0.380 mole of barium nitrate is allowed to react with an excess of phosphoric acid, how many moles of barium phosphate could be formed? 3Ba(NO3)2 + 2H3PO4 —> Ba3(PO4)2 + 6HNO3 5. Calculate the number of grams of carbon dioxide produced from the burning of 1.65 moles of C3H8. C3H8 + 5O2 —> 3CO2 + 4H2O 6.
C1.4.3 Hydrocarbon fuels Additional guidance: a) Most fuels, including coal, contain carbon and/or hydrogen and may also contain some sulfur. The gases released into the atmosphere when a fuel burns may include carbon dioxide, water (vapour), carbon monoxide, sulfur dioxide and oxides of nitrogen. Solid particles (particulates) may also be released. Candidates should be able to relate products of combustion to the elements present in compounds in the fuel and to the extent of combustion (whether complete or partial). No details of how the oxides of nitrogen are formed are required, other than the fact that they are formed at high temperatures.
Seventy five percent of the table is made up of metals, and a couple of the columns on the right of the table have gases. There are only two elements that are liquids- mercury and bromine. Column 1 contains the alkali metals, which suddenly combust when exposed to air or water. Columns 3-12 are the transition metals, which contain heavier atoms, which are more flexible in how they organize their electrons. Column 17 is made up of the more reactive gases- the halogens.
They used liquid and solidified nitroglycerin but later applied the same methods with water and gas to achieve a greater outcome. It wasn’t until the 1930s that acid was used as a nonexplosive fluid. The process of fracking uses high pressure and a pipe where the mixture of water, sand, and chemicals is forced down to cause near shale rock to crack. Once
How many moles of ammonium sulfate can be made from the reaction of 30.0 mol of NH3 with H2SO4 according to the following equation: ans. 15 mol (NH4)2 SO4 2NH3 + H2SO4 ( (NH4)2 SO4 2. In a very violent reaction called a thermite reaction, aluminum metal reacts with iron(III) oxide to form iron metal and aluminum oxide according to the following equation: Fe2O3 + 2Al ( 2Fe + A12O3 a. What mass of Al will react with 150 g of Fe2O3? ans.
Discussion & Conclusion In this experiment we learned how to synthesize the cyclohexene by dehydration of cyclohexanol. We procedure the first step where we have to mix the components. Then we heat the R.B.F with a fractionating column, distilled water. Then we obtained the layers, and we transferred the organic layer to a small, dry Erlenmeyer flask. We added anhydrous Sodium Sulfate as a drying agent.
There will have some error. 2) A volatile liquid was allowed to evaporate in a 43.298 g flask that has a total volume of 252 ml. the temperature of the water bath was 100˚C at the atmospheric pressure of 776 torr. The mass of the flask and condensed vapor was 44.173 g. calculate the molar mass of the liquid. T = 273 + 100 = 373 V = 252 mL = 1 L / 1000 mL = 0.252 L P = 776 Torr R= 0.0821 mass of 44.173 - 43.298 g = 0.875g moles of gas = PV / RT = 776 x .252 / 62.363 x (273+100) =0.00841 moles molar mass = 0.875g / 0.00841 moles = 104.1 g/
One of the increasingly popular types of gasification is Plasma Gasification. Plasma gasification technology has been shown to be the most effective and environmentally friendly method for solid waste treatment and energy utilisation. It is a non-incineration thermal process that uses extremely high temperatures in a partial oxygen environment to decompose completely the input waste material into very simple molecules. The products of the process are a fuel or gas known as synthesis gas and an inert vitreous material known as slag (Stehlı´k, 2009). Plasma gasification uses an external heat source to gasify the waste, resulting in very little combustion.
Once this is completed, a perforating gun is lowered into the well. When fired, the gun will create cracks in the rock (Fischetti , 2010). The gun is then removed and a mixture of water, sand and chemicals is pumped into the well under pressure. The intense pressure forces thousands of cracks to open up in the gas laden rock formations. The natural pressure existing in the well forces the water and chemicals back up the well.
