Some fuel cells are powered by hydrogen. Scientists are looking into the decomposition of water (H2O) to make hydrogen fuel with
skad [1K]

Here we have to choose the challenge which is faced by the scientist to make a hydrogen fuel cell by using water.

The challenge that the scientists are facing a. decomposition of water requires a high energy.

For the generation of fuel cells by hydrogen the use of water (H₂O) is a challenging task as the H-O bond in  water is so strong and need high activation energy.

As per the mechanism of hydrogen fuel cell generation of H₂ is compulsory. Water remains in its solution as H₂O⇔H⁺ + OH⁻. The breaking of hydroxide ion (OH⁻) to form free hydrogen need a high energy, which cannot meet easily by any energy source.

The sun is always a renewable energy source as the energy of sun is infinitive.

The decomposition of water will only produce oxygen (O₂) and hydrogen (H₂) among which H₂ will be used in the fuel cell and O₂ is not at all harmful.

The excess O₂ is always good for the environment as it is the breathing source in the living system.

What are the 5 steps in nuclear production​
ira [324]

The first step is splitting the atoms. Then there are control rods that absorb free floating nerons that are a result of fission. Next they heat they water pipe. Finally when they heat the pipe and water it turns to steam and they use it to harness energy!

The chemical equation below shows the reaction between carbon dioxide (CO2) and lithium hydroxide (LiOH). CO2 + 2LiOH mc011-1.jp
Sunny_sXe [5.5K]
From the given balanced chemical equation,
                            CO2 + 2LiOH --> Li2CO3 + H2O
we can conclude that for every 2 moles of LiOH, we need a mole of CO2. Calculate first the number of moles of CO2 by dividing the given mass by the molar mass giving us an answer of 0.58 moles. Using proportionality,
                             0.58 / x = 1 / 2
The value of x is equal to 1.16 moles.
