Two motivators for the use of hydrogen as an energy carrier today are to provide a transition strategy from hydrocarbon fuels to a carbonless society and to enable renewable energy sources. The development of a high efficiency, low emissions Hydrogen Internal Combustion Engine (HICE) will lead to establishing a path for renewable hydrogen based fuel utilization. There is a major controversy between whether to use the HICE or the Gas Engine, as well as why to use each over the other. There are

The given purpose of this lab was to separate and identify the pure substances in the sludge, however, the lab had a larger purpose. In this lab, we used our newly-found knowledge of characteristic properties to fulfill the given purpose. It taught us how to use critical thinking and grit when faced with a challenge, and to use all of the tools that IPS this year has taught us. In a nutshell, characteristic properties are properties that will remain the same, no matter the volume of a given substance

Alternately, low vegetation cover following fires is evident in shrublands due to their high flammability, where most of the woody material and leaf litter are burnt (Walsh and McDougall 2004). Studies on post-fire recovery of sub-alpine treeless vegetation in Victoria suggest that there is a trend toward increased shrub frequency over the short to

Why does it not burn? Dixie cups are paper/cardboard coated in polyethylene. It does not burn when water it’s filled because it is hydrophilic and also the water absorbs heat. 2) Discuss the flammability of Dixie Cups? Dixie Cups flammability is high because it is made out of plastic which is a recipe for combustion when exposed to oxygen and heat 3) What compound made up the black soot? Give an explanation for your reasoning In my opinion the compound that made

causing the many unwanted flames in the water. Petroleum ether has many physical and chemical properties that led me to believe it was the contender causing the problem. After watching the video of the burning water, petroleum ether’s slightly flammability, white color, insolubility in water, and extremely low flash point has caused me to believe it is the chemical to blame. I am certain that petroleum ether has caused the Big Darby Creek to burst into flames numerous times. In the material safety

Sludge Test Conclusion - Zoey Xeros and Lauren Head A clear, colorless liquid was separated using fractional distillation. The identity of this unknown liquid was found by the characteristic properties of flammability, density, sugar solubility, boiling point, and odor. The liquid ended up being flammable, and the density was below the average 0.79 g/cm3. Instead, we found 0.69 g/cm3. For the sugar solubility, it was found to be insoluble. The boiling was found to be higher than the average is 57C

Unknown 1 is sodium chloride(NaCl) which is ionic because sodium is a metal and chlorine is a nonmetal, unknown 2 is copper chloride(CuCl2), unknown 3 is citric acid(C6H8O7), and unknown 4 is sucrose(C12H22O11) which is also known as table sugar. From this information gathered from the facts, it can be concluded that unknown 1 and 2 are ionic, and 3 and 4 are covalent. Ionic compounds have the characteristics of having a crystalline structure, a brittle and hard texture, not being able to burn

Methanol Methanol is one of the most versatile compounds and one of the top ten chemicals produced in the chemical industry. The methanol industry spans the entire globe, with production in Asia, North and South America, Europe, Africa and the Middle East. Worldwide, over 90 methanol plants have a combined production capacity of about 100 million metric tons (almost 33 billion gallons or 90 billion liters), and each day more than 100,000 tons of methanol are used as a chemical feedstock or as a transportation

Firebrand storms are understood as the only mechanism that can initiate a spot fire at long distances from the fire front. The surface area of the firebrands play an important role in speeding of fire via firebrand. In this paper, the surface area of 1400 firebrands was measured via image processing techniques and then, the uncertainty of the measurement is calculated. It was found that the mean, variance and skewness of the projected area are 3.90, 41.01 and 6.62 respectively. Moreover, the standard
