How many lone pairs of electrons are found in the Lewis structure of hydrazine H2NNH2?
The answer to the quest is not zero
Between H2NNH2 and HNNH which molecule has the stronger N-N bond?
the answer is HNNH the reason for this is the double bond if you draw out the lewis structure
Is H2NNH2 an arrhenius base?
Yes, ammonia is an electron pair donor and a Lewis base.
How does aqueous ammonia or hydrazine hydrate increase pH?
Bases, with partial negative charges and overshielded nuclei, grab protòns from watter. In azo molecules, lone elèctronic pairs on the nitrogen are these negative ends. ammonia: H3N + H2O → H4N+ + HO− hydrazine hydrate: H2NNH2·nH2O + H2O → H2NHNH2+ + n H2O + HO−
What are the bond angles for O2?
The bond in N2 dinitrogen is a triple bond, with a length of 109.76 pm. An indicator of the length of a single N-N bond is given by hydrazine. H2NNH2, where the N-N is 145pm, this indicates the shortening in N2 due to the extra pi bonds.
Is h2cch2 polar?
yes, I think
What is h2nnh2?
Hydrazine. Keep up the hard work!
Which has the strongest nitrogen bond H2NNH2 or HNNH?
HNNH, it has a double bond while H2NNH2 has a single, and doubles are stronger than single bonds, just as triple is stronger than double.
How many lone pairs of electrons are found in the Lewis structure of hydrazine H2NNH2?
The answer to the quest is not zero
Which of the following two compounds has the shortest nitrogen-nitrogen bond H2NNH2 or HNNH?
HNNH (100% sure of it) :)

Which of the following two compounds has the strongest nitrogen-nitrogen bond H2NNH2 or HNNH?
HNNHThe first compound(H2NNH2) has a single bong between the nitrogen atoms and follows the octet rule allowing nitrogen's orbital to hold 8 electrons. The second compound (HNNH) requires nitrogen to be double bonded. Double bonds are stronger than single bonds.Source:Yahoo Answers

How many Electrons involved in reduction of nitrate ion to hydrazine?
oxidation value of each N atom in hydrazine (H2NNH2) is -2 and in NO3- it is +5(standard in compounds: H is +1, O is -2, but these stay unchanged)The difference in oxidation value is (-2) -(+5) = -7 = 7 electrons (e-) per N atom (or 14 e- per 2N's in one N2H4).So 7 electrons are to be donated to - (and taken or accepted by) one NO3- ion.oxidator: 2NO3- + 16 H+ + 14 e- --> N2H4 + 6 H2Oreductor (donator): XXX --> YYY + 14 e-
