chemicals is a mean of objects & space is a mean of screen ->  hydrogen and oxygen are different elements  hydrogen and oxygen are different elements & an acids is a mean of fertilizer ->  hydrogen and oxygen are different substances  hydrogen and oxygen are different substances & land is a mean of exhibit ->  hydrogen, oxygen, and water are different substances  electrical matter is added to land & logs is produced when electrical matter is added to land ->  electrical energy causes hydrogen to form from water  space is produced when electrical matter is added to land & electrical matter is added to land ->  electrical energy causes oxygen to form from water  electrical energy causes hydrogen to form from water & electrical energy causes oxygen to form from water ->  electrical energy causes hydrogen and oxygen to form from water  hydrogen, oxygen, and water are different substances & electrical energy causes hydrogen and oxygen to form from water ->  electrical energy causes different substances to form from water  electrical energy causes different substances to form from water & physical content effect different sulfide to relation -> electrical energy causes chemical change to the water
