It helps in keeping food fresher, longer. In Frozen, chilled, crisp, fresh, fizzy . They use hydrogen to make hydrogenated vegetable oil such as margarine by using nickel as a catalyst and combining hydrogen with vegetable oil.it is also required for crude oil refinements

group2- gia, sweta, tina, shuchi, aditi, aileen. Hydrogen fuel is a zero-emission fuel when burned with oxygen (if one considers water not as an emission) or used in a contained cell also capable of 'reversing' the reaction if needed. It often uses electrochemical cells, or combustion in internal engines, to power vehicles and electric devices. It is also used in the propulsion of spacecraft and might potentially be mass-produced and commercialized for passenger vehicles and aircraft.

Metals are very useful. Ores are naturally occurring rocks that contain metal or metal compounds in sufficient amounts to make it worthwhile extracting them. The method used to extract a given metal from its ore depends upon the reactivity of the metal and so how stable the ore is.

Very reactive metals are extracted using electricity, while less reactive metals are extracted by reduction with carbon.

Hydrogen is also used to convert saturated fats to unsaturated fats.

Hydrogen (H2) which is a fuel reacts with oxygen (O2) to form water (H2O) which is a fuel cell and helps in regenerating electricity for battries, D. C. Powers, and A C Powers for inverters.
