That is where hydrogen fuel cells come into the picture. Rather than depending on a foreign countries oil‚ to provide fuel‚ businesses today should look to hydrogen as an alternative fuel source. The United States is too dependent on foreign oil. If something were to happen‚ like another war with the Middle East‚ we would not have any oil to power our cars or heat our homes. That’s why hydrogen is the answer. Everybody could make their own fuel for their country by creating hydrogen plants and buying

re-fuel‚ launch‚ educate and distribute?) Benefits. No pollution: A great benefit of using Hydrogen fuel cells is that they give off no pollution‚ and in fact produce pure water as a byproduct. Even though currently engineers are concentrating on producing hydrogen from natural gas‚ it will be for a short-term. Scientists are planning to have renewable environmentally-friendly ways of producing hydrogen in the future. Efficiency: Fuel cells generate electrical power quietly and efficiently. Approximate

Lab 2 Report- Identification of Substances by Physical Properties The purpose of this lab was to see how certain substances; Naphthalene‚ Toulene‚ and and 2 unknowns (one liquid‚ one solid) react with 3 different solvents. To identify the two unknowns‚ testing needs to be done to find the density of both the liquid and the solid‚ determine the melting point of the solid‚ and the boiling point of the liquid. The Physical Properties of Pure Substances Table can then be used to compare the observed
