- Q5What is a major challenge in using hydrogen as a fuel for vehicles?It is not flammableThe difficulty of storing and transporting hydrogen2...It is very easy to liquify and storeIt doesn't produce water30s
- Q6In a fuel cell, where do electrons flow after being released by hydrogen?Directly into the atmosphereInto the water produced by the fuel cellThrough an external circuit to power a device4...Back to the hydrogen atoms30s
- Q7What is the role of a catalyst such as platinum or nickel in a fuel cell?To prevent the flow of electronsTo provide structural support for the electrodesTo accelerate the reaction at the electrodes4...To increase the volume of the fuel30s
- Q8Why is steam reforming of methane considered problematic despite being a method for hydrogen production?Because it is too expensive to useBecause it releases carbon dioxide1...Because it requires a large amount of waterBecause it does not produce enough hydrogen30s

- Q13The sources suggest that hydrogen production by electrolysis is more environmentally friendly if:It uses nuclear powerIt uses renewable sources of electricity1...It uses low amount of waterThe process is not energy intensive30s
- Q14Based on the sources, what is a main reason that hydrogen has not previously taken off as a widely used fuel?Hydrogen is not safeThere were no demands for a low carbon fuelThe technology was not advanced enoughThe cost and inefficiencies of hydrogen production1330s
- Q15According to the sources, what is the relationship between the energy put into hydrogen production and the energy obtained from it?The energy content that comes out is equal to what goes inThe energy content that comes out is more than what goes inThe sources don't specify the relationshipThe energy content that comes out is less than what goes in4...30s
