Conclusion In the experiment held various sizes of hydrogen gas bubbles, which were made through pumping hydrogen gas in a soap mixture, then later ignited with fire to see the combustion and how long it last; our hypothesis was any bubble that measured under or equal to 1mm would not have any combustion, therefore no combustion time. Through the several trials that were held for each size bubble its been proven that all bubbles under 1mm had no combustion time and bubbles around 1mm to 3mm had had at the rang of a half second combustion time to an occasional 1-2 . Bubbles that were 4mm and higher though had a longer combustion time at the most 8 seconds. The complications we encountered through the experiment was definitely measuring the bubbles accurately. To measure them we first tried to use a ruler against the container the soap mixture was in while we pump hydrogen gas in and make the closest size to the millimeter we were on. Then we went back and redid the measuring by using graphing paper the has millimeter long boxes so we could wrap it around the container we had, so we could get way more accurate measuring. Another measuring problem we had was timing the experiment as accurately as we could, so that’s why we did three trials each for each size bubble. Through the experiment we learned how energy released appears as heat, light, sound , and kinetic energy, similar to a combustion engine in a car. Therefore using hydrogen could be used as an alternative…
World consumption of oil is about 90 million barrels per
day or about 30 billion barrels of oil per year.
World consumption of natural gas is about 300 billion
cubic feet per day or about 100 trillion cubic feet per year.
FRACKING – involves applying high pressure water to break rocks, in order to extract shale
gas, which is a natural gas that could replace oil. Challenge is horizontally drilling, since it is
very deep. Shale is a sedimentary rock.

Electricity is a very convenient form of energy which is being used in most of necessary devices supporting modern life. About three – quarters of electricity generated in the UK comes from power stations fueled by fossil fuels such as coal, oil and natural gas. Normally electricity is converted through a two step process. Fuels are burnt converting chemical energy to heat. The heat is then transformed into electricity by generating steam to turn turbines. This is a highly inefficient method which requires…

Hydrogen Fuel Cells: Impacting More Than Just Cars
Gas prices continue to increase and current alternatives are either ineffective or more costly; however, hydrogen fuel cells, when used in vehicles, have the potential to replace gasoline as a fuel source. One of the main benefits of vehicles powered by hydrogen fuel cells is that they would bolster the United States economy. As well as strengthening the economy, hydrogen fuel cell vehicles would greatly reduce the amount of pollution…
Have you ever wanted to have more money? Maybe u wanted to save up for a submarine. Well you with all the money you would save while buying a hydrogen car. Americans spend about 378 million dollars on gas daily or as my dad would say 378 thousand bicycles.
Did you know that the first 'the world's first internal combustion powered automobile use hydrogen as their fuel source. It was created in 1807 by a known tinkerer Francois Isaac de.
Now you might be saying this stuff…
Hydrogen is a chemical element with chemical symbol H and atomic number 1. With an atomic weight of 1.00794 u, hydrogen is the lightest element and its monatomic form (H) is the most abundant chemical substance, constituting roughly 75% of the Universe's baryonic mass.[note 1] Non-remnant stars are mainly composed of hydrogen in its plasma state.
At standard temperature and pressure, hydrogen is a colorless, odorless, tasteless, non-toxic, nonmetallic, highly combustible diatomic gas with…

Hydrogen: A Reliable Source of Energy for Our Children
“Society cannot exist without energy” (Nakaya 8). Energy is used
to provide heat, to cool and light their homes, to refrigerate and cook their food, and to
fuel transportation. It also provides power for telecommunications, commercial and
industrial activity (8). Andrea Nakaya states that, “Humans are virtually helpless
without a reliable energy source, such as, the element Hydrogen” (8). In addition, many…
It is involved in the following equation which causes the breakdown of Hydrogen Peroxide into water and oxygen:
Hydrogen Peroxide Water + Oxygen
2H2O2 H2O + O2
When we immerse small discs of filter paper into the yeast suspensions and then drop them into our solution of hydrogen peroxide, a reaction occurs. This reaction involves bubbles being produced that are attached to the filter discs and these bubbles force them to rise to the surface of the solution.
To test that…
Does The Concentration Of Hydrogen Peroxide Affect The Time Taken For A Bead To Lift Off?
Data Collection and Processing & Conclusion and Evaluation
Data Collection and Processing
When dropping the bead into the different concentrations the beads slowly sank to the bottom, bubbles formed around the bead before it took off.
As the concentration of hydrogen peroxide increased the time that the bead took to rise decreased.
At 1.0molL-1 the bead almost instantly…
