The nitrogen cycle<span> is the biogeochemical </span>cycle<span> by which </span>nitrogen is converted into various chemical forms . p<span>lants consume nitrogen in </span>the form<span> of nitrates. nitrogen gets converted into nitrates by the denitrifying bacteria , then these plants absorb nitrogen in </span>the form<span> of nitrates through the groundwater , then consumed by the animals as food.</span>
Fossils are formed in different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind
Answer:
O2 is a covalent substance while NaCl is an ionic substance
Explanation:
In O2 molecule, the bond is between 2 oxygen atoms which are non - metals. Thus, this is a covalent bond since it involves 2 non metals.
Whereas, for the NaCl molecule, the bond is between a metal sodium (Na) and a non metal Chloride(Cl) and thus we can say this is an ionic bond.
Thus the difference is that O2 is a covalent substance while NaCl is an ionic substance.
Answer is because
