Researchers harness viruses to split water: Crucial step toward turning water into hydrogen fuel
(PhysOrg.com) — A team of MIT researchers has found a novel way to mimic the process by which plants use the power of sunlight to split water and make chemical fuel to power their growth. In this case, the team used a modified virus as a kind of biological scaffold that can assemble the nanoscale components needed to split a water molecule into hydrogen and oxygen atoms.

we can use hydrogen as a fuel for car,so y can’t we get hydroden from water(h2from h2o)by cuttin o2 ?

we can get hydrogen from water byu reduction of oxigen like oxidation,is it possible,water as a fuel for car?

Yes there are ways to strip off oxygen from water, aluminum gallium alloy or you can take aluminum, lye and water mixed together and the reaction will give off hydrogen, now here’s the but, it takes more engery to recover the aluminum or make the aluminum than you get back. You would be money ahead just to sell the aluminum and buy gasoline.

There are some test cars that use a aluminum gallium alloy add water and you get hydrogen, but it cost more to recover the aluminum and gllium then the price gasoline.

If you could come up with a cheap enviormently friendly was to recover the aluminum then you might have something there.

You could use electrolysis to break water apart, but again you would be far better oft charging a set of batteries and using them instead of breaking water apart.

Trust me if it was cheaper than gasoline we’d be using it already.

EDIT

The plans from the guy above won’t work, that system can’t produce enough hydrogen to run a car, not hard to prove by the way, basically its the HHO con.

Do we really have the technology to seperate hydrogen from water and burn it as a fuel?

Written by admin on February 17, 2010 – 8:46 am -

imagine what the "fossile fuel" industries would do to those responsable for such a discovery!

It’s easy to do, but it does not give you any energy.

Why not? Because the energy required to split water is greater than the energy you get back from burning the hydrogen as fuel.

How to separate Hydrogen from water?

Written by admin on February 15, 2010 – 10:36 am -

I’ve seen this done using electricity.

Two electrodes are placed in water, usually with a bit of salt added to allow current to flow. Pure water is actually a good insulator. At the positive electrode oxygen will form and at the negative electrode hydrogen will form. The voltage needs to be above 1.6-2 volts

These can be collected by placing test tubes filled with water and inverted over the electrodes to captures the bubbles.
The usual tests for hydrogen can be performed with a lit splinter (the hydrogen will ignite with a pop) or a smouldering splinter for the oxygen (it will burst in to flame).

The previous replies about hydrogen being lighter than oxygen do not seem to understand mixing of gases and in fact the oxygen and hydrogen will simply be mixed up if collected in to a single vessel.

You will often see this performed in museum exhibits, where the cell is electrolysed and the resulting gasses then popped with a spark igniter such that the gases turn back to water and the cycle is then repeated..

How much water can be made from 5.41 ×1024 hydrogen molecules?

How much water can be made from 5.41 ×
1024 hydrogen molecules? Answer in units of
g.

297 g. You would convert the number of H2 molecules to moles by using avogadro’s number. Next, after writing the balanced equation for the formation of water by hydrogen and oxygen, use the coefficients of the hydrogen and water to form a ratio and then convert the moles of water to grams of water.

2H2 + O2 —> 2H2O

5.41E24 molecules H2 * ( 1 mole H2 / 6.022E23 molecules H2)* (2 moles H2O / 2 moles H2) * (33.01 g H2O / 1 mole H2O) = 297 grams H2O

How much hydrogen can be produced from 685 g of methane and 1530 g of water?

Written by admin on February 3, 2010 – 1:16 pm -

CH4(g) + H2O(g) CO(g) + 3 H2(g)

Hydrogen can be prepared by reacting natural gas (methane) with water, as shown above.How much hydrogen can be produced from 685 g of methane and 1530 g of water?

____g

CH4(g) + H2O(g) —- > CO(g) + 3 H2(g)

calculate moles of each reagent and determine limiting reagent

moles = mass / molar mass
moles CH4 = 685 g / 16.042 g/mol = 42.7 moles

moles H2O = 1530g / 18.016 g/mol = 84.92 moles

The balanced equation shows that CH4 and H2O react in a 1 : 1 ratio
1 mole CH4 needs 1 mole of H2O to fully react

So since there are less moles of CH4 then H2O then CH4 is the limiting reagent

The maximum amont of product possible is if all the limiting reagent is used up.
1 mole Ch4 produces 3 moles H2
So 42.7 moles CH4 can produce (3 x 42.7) moles H2
= 128.1 moles H2

mass = molar mass x moles
mass H2 = 2.016 g/mol x 128.1 g
= 258 g

How much water can be made from 5.41 ×
1024 hydrogen molecules? Answer in units of
g.

2 H2 + O2 = 2 H2O
moles H2 = 5.41 x 10^24 / 6.02 x 10^23=8.99

the ratio between H2 and H2O is 2 : 2 ( or 1 : 1)

moles water = 8.99

mass water = 8.99 mol x 18.02 g/mol=161.9 g

what is the correct procedure for extracting hydrogen from water with electrolysis?

Written by admin on January 25, 2010 – 6:33 am -

how is it kept seperate from the oxygen

Two ions exist in the water(considering it is pure).

At Anode, oxygen is released.

4OH- —–> 2H20 + O2(gaseous) + 4e-

At Cathode, hydrogen is released.

2H+ + 2e- ——> H2

How many L of O2 are released from the decomp of 3.6 L of hydrogen perox. gas to produce water vapor + oxygen?

Written by admin on January 18, 2010 – 3:11 pm -

Volume – Volume

How many liters of O2 are released from the decomposition of 3.6 L of hydrogen peroxide gas to produce water vapor and oxygen?

Please show the process.

2 H2O2 –> 2 H2O & O2

the identical ratio of
2 moles H2O2 produces 2 moles of H2O
tells us that those two gases also ratio in volume 1 to 1

so 3.6 Litresf H2O2 produces gas
your answer:
3.6 litres of H2O gas
