Hydrazine, N2H4, is a good reducing agent that has been used as a component in
Taya2010 [7]

Answer:

Explanation:

Data Given

Formula of hydrazine = N₂H₄

Lewis structure of hydrazine (N₂H₄) =?

Solution:

  • Hydrazine (N₂H₄) contains 2 Nitrogen atoms and 4 Hydrogen atoms
  • Nitrogen atom have 5 valence electrons
  • Hydrogen have 1 valance electron
  • So it have 14 total number of valance electrons

                     N₂ H₄ = 2 (5) + 4(1) = 14 no. o electrons

  • it is a stable compound and obey octet rule for nitrogen and duplet rule for hydrogen by sharing of electrons.

To draw the Lewis Structure

  • Put the 2 nitrogen in center and draw the Hydrogen on the outside
  • Put the 2 hydrogen on out side of each of the nitrogen
  • Then draw the 2, 2 valence electrons between atoms that form chemical bond
  • So we will draw total 14 electrons in the structure
  • then we count electrons around each atom of nitrogen and hydrogen that it have 8 and 2 electrons to complete its octet and duplet respectively

Which changes of the state takes place when an igneous rock turns into sedimentary rock?
Katena32 [7]
All rocks on Earth take part in the "Rock Cycle". For an igneous or metamorphic rock to change into a sedimentary rock, they must undergo weathering and erosion by wind, water, and/or ice. The broken down pieces of rock (sediments) settle into layers that form a sedimentary rock.
