In
Methyl Amine the Nitrogen atom is attached to two Hydrogen Atoms and one Methyl (CH₃-) group. From
Lewis structure it is shown that the Nitrogen atom also contains a
lone pair of electron.
So,
According to
Valence Shell Electron Pair Repulsion (VSEPR)
Theory, those central atoms which have four electron pairs and all of them are bonding electron pairs gives
Tetrahedral Geometry.
Methylamine also contains four electron pairs, but out of four only
three are bonding pair electrons and
one lone pair electron. Now, due to presence of lone pair of electron (which has
greater repulsion effect than bonding electron pair) the bond angle between H-N-H will decrease from
109° to 107° and results in the formation of <span>
Trigonal Pyramidal geometry as shown below,</span>
I think that it's cannot include supernatural explanations, or C.

Answer:
43.5 moles of HNO₃.
Explanation:
The balanced equation for the reaction is given below:
S + 6HNO₃ —> H₂SO₄ + 6NO₂ + 2H₂O
From the balanced equation above,
6 moles of HNO₃ reacted to produce 2 moles of H₂O.
Finally, we shall determine the number of mole of HNO₃ required to produce 14.5 moles of H₂O.
This can be obtained as illustrated below:
From the balanced equation above,
6 moles of HNO₃ reacted to produce 2 moles of H₂O.
Therefore, Xmol of HNO₃ will react to produce 14.5 moles of H₂O i.e
Xmol of HNO₃ = (6 × 14.5)/2
Xmol of HNO₃ = 43.5 moles
Therefore, 43.5 moles of HNO₃ is required to produce 14.5 moles of H₂O.
Answer:
It is a sigma bond
Explanation:
Chlorine has an electronic configuration of 1s2 2s2 2p6 3s2 3p5. This means that the outermost n=3 level has seven electrons. Hence one more electron is needed for the octet of outermost electrons to be achieved. As a result of this, chlorine enters into covalent bonding with another chlorine atom to form Cl2.
The outermost 3p electrons of the two chlorine atoms are now shared to form a p-p sigma bond (a single bond). Hence, the Cl2 molecule contains a sigma(single) bond between two chlorine atoms. Hence the answer written above.
C. Protons
Protons are subatomic particles found in the nucleus and carry positive electrical charge.
