Answer:
Tetrahedral electron geometry and trigonal pyramidal molecular geometry.
Explanation:
The Lewis structure is shown in Figure 1.
The central N atom has three bonding pairs and one lone pair, for <em>four electron groups</em>.
VSEPR theory predicts a tetrahedral electron geometry with bond angles of 109.5°.
We do not count the lone pair in determining the molecular shape.
The molecular geometry is trigonal pyramidal (see Figure 2).
Answer:
The number of moles of O atom in mol of
= 1.6
Explanation:
1 molecule of contains 2 atoms of O
So, molecules of
contains
atoms of O.
We know that 1 mol of an atom/molecule/ion represents numbers of atoms/molecules/ions respectively.
So, molecules of
is equal to 1 mol of
.
atoms of O is equal to 2 moles of O atom.
Hence, 1 mol of contains 2 moles of O atom.
Therefore, mol of
contains
moles of O atom or 1.6 moles of O atom.
