thing in automotive fuel may very well be hydrogen. Automakers rapidly are closing in on making hydrogen fuel cell vehicles an everyday fact of life‚ with several test models set to debut over the next few years. Hydrogen fuel cells to power vehicles are desirable‚ experts say‚ because hydrogen is a renewable fuel that can be used to create electricity to run cars. A chemical reaction between oxygen and hydrogen produces the electric power‚ and when pure hydrogen is used‚ the only emission from the tailpipe

In the ecosystem project‚ there are three chambers. The three chambers in our ecosystem are aquatic‚ decomposition and terrestrial. We formed a hypothesis about what would happen to the biotic factors in each chamber of the ecosystem. For the aquatic chamber‚ we stated that the fish would die if the fish did not receive enough oxygen and enough food in the tank. The decomposition chamber did not have a lot of changes much because there is no activity or life in that chamber besides the the potato

THE EFFECT OF HYDROGEN BONDING ON RESISTING FLOW Design Investigating a factor affecting the viscosity of a mixture of liquid Research Question The effect of hydrogen bonding on resisting flow of five different liquids Background Theory Viscosity is the resistance of a fluid to flow‚ either within itself‚ or to moving past an objects moving through it. A liquid with high viscosity is thick and flows slowly. A liquid with a low viscosity is thin and flows quickly. Different liquids

relation to this dilemma. Past research has shown that hydrogen fuel cells can quite possibly replace the country’s current usage of oil while having a more positive effect on the environment. However‚ environmentalists have conducted their own contradicting research on fuel cells reflecting negative effects on the environment. Numerous articles have been published which express both sides of this debate. Although some scientists believe hydrogen fuel cells will improve the environment and rid the United

Hydrogen Fuel Cell Cars: Worth the Investment? Hydrogen is the most abundant element in the universe‚ but only recently have people been able to harness this resource and turn it into energy. Hydrogen fuel cell cars are one such advancement made in the effort to turn hydrogen gas into electricity. Fuel cells in the car are used to convert hydrogen into an electrical current‚ and thus power the vehicle. Fuel cells convert hydrogen and oxygen into water while producing electricity. Hydrogen fuel

Discuss why hydrogen bonding is essential for life Throughout biochemistry there are many bonds without which life as it is on earth today would not be possible. One of the most important bonds of these is the hydrogen bond‚ a weak chemical bond that is present in essential biological molecules such as water and polypeptides. A hydrogen bond is defined by Campbell and Reece as occurring when a hydrogen atom is covalently bonded to an electronegative atom but attracted to another electronegative
