Question

Some fuel cells are powered by hydrogen. Scientists are looking into the decomposition of water (H2O) to make hydrogen fuel with the help of the Sun’s energy. What challenge do scientists face with this task


A.Decomposing water requires a high activation energy.

B.The Sun isn't a renewable resource.

C.Decomposing water results in toxic byproducts.

D.Scientists are uncertain what to do with the excess oxygen.

Answer 1

Answer:

A is right

Explanation:

Answer 2

Answer:

The correct answer is option A. Decomposing water requires high activation energy.

Explanation:

The decomposition of water needs a lot of electrical energy or heat input, developed from some primary energy source (fossil fuel, for example). This amount of energy contains a substantial effect on nature and exists an expensive procedure that would improve the economic value of hydrogen fuels. For this cause, we can conclude that the challenge facing scientists for hydrogen fuel exhibition exists that the decomposition of water needs high activation energy.

In theory, hydrogen exists as the dream fuel. In approach, things exist trickier. Emanated from the most abundant component in the universe, hydrogen fuel exists as clean, flexible, and energy-efficient. Current projections demonstrate that by 2030 the hydrogen economy could be worth $500bn.

Therefore, the correct answer is option A. Decomposing water requires high activation energy.
