Source sentences:
text: In a flame of pure hydrogen gas, burning in air, the hydrogen (H 2 ) reacts with oxygen (O 2 ) to form water (H 2 O) and releases energy.
text: Hydrogen is a clean fuel that, when consumed in a fuel cell, produces only water.
text: Since they are both gases at STP, hydrogen can be simply burned in the presence of oxygen to form water in a highly exothermic reaction; such a test can be used in beginner chemistry to test for the gases produced by a reaction as hydrogen will burn with a pop.
text: Hydrogen can be used in fuel cells to generate power using a chemical reaction rather than combustion, producing only water and heat as byproducts.
