Whats Going To Happen When Fuel And Water Run Out?

the fuel is almost gone, and people are trying to find a substitute for it but i don’t think that will be enough. we are using fresh water more and more, so some day we will be stuck with dirty water. what do you think will happen?

When Hydrogen Gas Is Being Dried Up,what Is The Purpose Of Sulphuric Acid In The Conical Flask?

Does sulphuric acid dry the hydrogen gas?

Is It About Time To Pull The Plug On Corn-ethanol? When Will The Scientists We Trusted Fess Up?

For the $Billions of tax-payer welfare that we are providing for this industry, shouldn’t our environment be cleaner? Is the farm lobby so strong that politicians won’t act on this utter waste of taxpayer dollars?
“Of all crops grown in the U.S., corn demands the most massive fixes of herbicides, insecticides, and natural gas-based fertilizers, while creating the most soil erosion.
Meeting the lifetime fuel requirements of just one year’s worth of U.S. population growth with straight ethanol (assuming each baby lived 70 years), would cost 52,000 tons of insecticides, 735,000 tons of herbicides, 93 million tons of fertilizer, and the loss of 2 inches of soil from the 12.3 billion acres on which the corn was grown.
Other parts of the biorefinery production process release pollution as well. Prodded by hundreds of complaints at the Gopher State Ethanol plant in St. Paul, where residents complained that the plant smelled like “rubbing alcohol mixed with burning corn,” the Minnesota Pollution Control Agency began testing emissions from the plant. They found high levels of carbon monoxide, methanol, toluene and other Volatile Organic Compounds, including formaldehyde and acetaldehyde, both of which are known to cause cancer in animals.
The EPA then tested other ethanol plants and concluded that “most, if not all” ethanol plants are emitting air pollutants at many times the rate allowed by their permits.
A National Academy of Sciences report concluded that the “commonly available ethanol and MTBE blends do little to reduce smog.” They also found that, compared with MTBE blends, ethanol blends result in more pollutants evaporating from vehicle gas tanks.
Ethanol costs three and a half times as much as gasoline to produce42 and contains only 60% as much energy per gallon as gasoline.43 So, while a gallon of ethanol-blended gas may cost the same as regular gasoline at the pump, it won’t take you as far.
Ethanol must be blended with gasoline. But ethanol absorbs water. Gasoline doesn’t. Therefore, ethanol cannot be shipped by regular petroleum pipelines. Instead, it must be shipped separately and mixed on-site. Shipping by truck, rail car, or barge are far more expensive than pipelines. They also carry larger risks of accidents during shipping.
Among the waste by-products of ethanol production is a corn mash known as distiller’s grains. a study published by Kansas State University researchers in December of 2007 found an increased prevalence of the deadly E. coli 0157 bacterium in the hind-gut of cattle fed distiller’s grains.
Ethanol production using corn grain requires 29% more fossil energy than the ethanol fuel produces. Using switchgrass requires 50% more; wood biomass: 57% more.”http://www.energyjustice.net/ethanol/fac…

When Carbon Monoxide Reacts With Hydrogen Gas, Methane And Water Vapor Are Formed According To The Following R?

When carbon monoxide reacts with hydrogen gas, methane and water vapor are formed according to the following reaction
CO(g) + 3H2(g) = CH4(g) + H2O(g)
Analysis at equilibrium shows that Keq = 0.555, the [CO] = 0.921 M, the [H2] = 1.21 M, and the [CH4] = 0.0391 M. Calculate the equilibrium concentration for the water vapor.
