Hydrogen may not be advantagous as a fuel

Hydrogen may not be advantageous as a fuel because...

- Its expensive

- Its difficult to store

- Its highly flammable

- Its dependent on fossil fuels

Explanation:

Its expensive - Not only is hydrogen gas expensive, but it also takes a lot of work to free from other elements. It is both expensive and time-consuming to produce.

Its difficult to store - Moving hydrogen is not an easy task. Moving anything more than small amounts of hydrogen was also very expensive, making it impractical.

Its highly flammable - When exposed to the atmosphere, hydrogen could potentially form explosive mixtures.

Its dependent on fossil fuels - Hydrogen energy itself is renewable. However, the process of separating it from oxygen uses non-renewable sources such as coal and oil.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
