Elemental nitrogen in the air occurs in diatomic molecules and therefore has the formula N2.
NBr3 is the chemical formula for nitrogen bromide
The chemical formula of nitrogen triiodide is NI3.
NiCO3 is the chemical formula for nitrogen carbonate.
Nitrogen dioxide is NO2NO2NO2NO2
Nitrogen monoxide is a compound with the chemical formula NO.
Free nitrogen is diatomic. Write the formula as: N2.
NBr3 is the chemical formula for nitrogen bromide
The chemical formula for nitrogen difluoride is NF2.
NP2 is the chemical formula for nitrogen diphosphide.
NCO3 is the chemical formula for nitrogen carbonate.
The chemical formula of nitrogen triiodide is NI3.
NiCO3 is the chemical formula for nitrogen carbonate.
Nitrogen dioxide is NO2NO2NO2NO2
Nitrogen trifluoride has the chemical formula NF3.
Formula: N2
Formula: N2
When you compress air it is a physical change, not a chemical change. so it is still 16% oxygen, 1% hydrogen, and 78% nitrogen. there is not a chemical formula for compressed air.
