Final answer:
Both hydrogen fuel cells in acidic and basic conditions convert hydrogen and oxygen into water, which is a true statement. This process is pollution-free and hydrogen fuel cells are known for their high energy efficiency and potential in renewable energy applications. Correct answer is a) True .
Step-by-step explanation:
The answer to the question of whether both hydrogen fuel cells in acidic or basic conditions convert H2 and O2 into water is true. The overall reaction in a hydrogen fuel cell, regardless of whether it operates in acidic or basic conditions, is 2H2(g) + O2(g) → 2H2O(g).
This reaction depicts the conversion of hydrogen and oxygen into water, and it is an essentially pollution-free process. As a result, hydrogen fuel cells are considered environmentally friendly and are being researched intensively for use in space missions and personal vehicles due to their higher energy efficiency compared to traditional internal combustion engines. therefore, Correct answer is a) True
