seem more suitable than hydrogen. The possibility of hydrogen as a fuel is ever increasing‚ with the advantages outweighing the disadvantages more every year. Car manufactures are already making cars that are hydrogen powered‚ although they are either prototypes or extremely limited production runs‚ but cars such as the Honda Clarity prove that hydrogen powered cars really are not a thing of the future‚ but a thing of the present.

that way if you believe in the power of change. Hydrogen fuel is that change for the automobiles of the future. Hydrogen has been used for decades‚ but mostly for commercial use. Each year‚ we get closer to removing the oil company’s choke hold on our wallets. It’s time to drive with a lighter purse and a cleaner environment and it’s time for hydrogen fuel. The two largest points of debate with hydrogen fuel are cost and production Hydrogen fuel is a cheaper alternative to our current source

HYDROGEN BONDING: Hydrogen bonding is a bonding type consisting of dipole and dispersion forces. A hydrogen bond is the attractive force between a hydrogen atom attached to a molecule and an atom of a different molecule. According to the Pauling scale of electro-negativities of the elements‚ it can be viewed that the three most electronegative elements in the periodical table are nitrogen‚ oxygen and fluorine. These are also called heteroatoms. The heteroatoms have a partial negative charge while

Hydrogen Fuel Cells There are many reasons to look for new cleaner forms of energy. Fossil fuels‚ being non-renewable‚ will eventually run out. Pollution from burning fossil fuels destroys our environment. Hydrogen fuel cells could be used many places where fossil fuels are currently being used. Using hydrogen as a form of energy can not only reduce our dependence on imported oil‚ but also benefit the environment by reducing emissions of greenhouse gases and pollutants that affect our air quality

ATOMIC THEORIES AND HISTORY * Democritus (Greek) - “atomus” meaning indivicible * Indivisible particles called atoms * John Dalton – MODERN ATOMIC THEORY: 1. All matter is made of tiny‚ indestructible particles called atoms (Democritus) 2. All atoms of a given element are identical (not accepted today bc isotopes) 3. Atoms are neither created nor destroyed in chemical reactions (Lavoisier) 4. Atoms of different elements form compounds in whole number ratios (Proust)
