Waxaan qeexi karaa astaamaha oksaydhka birta iyo oksaydhka aan birta ahayn waxaana u qori karaa isla'egyo matalaya falcelinta oksaydhka birta ee aashitada.
Hordhac
Ku soo dhawoow darsiga maanta ee oksaydhka biraha iyo oksaydhka aan-birahayn. Kani waa qayb ka mid ah cutubka loo yaqaan asiidhyada iyo saldhigyada. Kahor intaadan bilaabin, waxaad rabaa inaad xasuusato sida curiyeyaasha (elements) ay u falgalaan oksijiinta, sababtoo ah darsigani wuxuu ku dhisan yahay aasaaskaas.
