Answer:
e−(Ea/RT): the fraction of the molecules present in a gas which have energies equal to or in excess of activation energy at a particular temperature
Answer:
<em>Figure attached </em>
Explanation:
A. Lewis dot structure
Number of electrons
Number of electrons by H = 1 e
Number of electrons by O = 6 (3)
Number of electrons by O = 18 e
Number of electrons by N = 5 e
Total in HNO3 = 24 e
Resonance structures
In resonance structures we mostly prefer 1st two structures because 3rd one have high charge so it is very unstable form then the other two. Figure 4 contains the hybrid structure which is mostly used in literature.
Answer: 20
Explanation: there you go my freind
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.
