Nitrogen gas has the chemical formula N2. One molecule of nitrogen gas is made up of two atoms of nitrogen.
The correct option is C.
Explanation:
Nitrogen gas has the chemical formula
, which means that two atoms of nitrogen element combined to form nitrogen gas.
The combination of two atoms of element nitrogen produce dinitrogen atom.
Dinitrogen is the nitrogen gas usually present in atmosphere of the earth in abundance.
2 atoms of nitrogen element
N + N = 
the gas is colorless and odorless formed at standard condition of temperature and pressure. The two nitrogen atoms are tightly bonded with triple bonds in between the atoms.
you can learn who's blood it is, you can also see the blood patterns and how the crime maybe happened.
Answer: Radon-222 is generated in the uranium series from the alpha decay of radium-226, which has a half-life of 1600 years. Radon-222 itself alpha decays to polonium-218 with a half-life of approximately 3.82 days, making it the most stable isotope of radon. Its final decay product is stable lead-20
Rise over run. Just like you have set up. If you plotted the data points subtract (y2-y1)/(x2-X1)
