Components of Fuel cell are Hydrogen and Oxygen gases.

Explanation:
Fuel cells are electrochemical devices which converts chemicals i.e. a fuel like H₂ and oxidants like O₂ into direct current (D.C).
As we know when hydrogen is reacted with oxygen it produces water along with heat. Same reaction is carried out in fuel cells in a very controlled way.
The Hydrogen gas is oxidized at anodes to convert it into H⁺ ions and electrons.

At Anode:
2 H₂ → 4 H⁺ + 4 e⁻

These electrons are passed through external circuit to Cathode. Meanwhile, the H⁺ ions passes through the porous anode to electrolyte to cathode chamber.

The electrons arrived at cathode reduces oxygen gas to O²⁻.

At Cathode:
O₂ + 4 e⁻ → 2 O²⁻

In cathode chamber O²⁻ reacts with H⁺ to produce water.

2 O²⁻ + 4 H⁺ → 2 H₂O

This water produced is utilized by Astronomers in Satellites.

wanahton purified a portion of water with 900 grams of contaminants. each hour, a third of the contaminants was filtered out.

let g(n) be the amount of contaminants (in grams) that remained by the beginning of the nth hour. g is a sequence, what kind of sequence is it, arithmetic or geometric? then, write an explicit formula for the sequence, g(n)=
