Answer:
C. 3.0
Explanation:
Bond order is number of the bonding pairs of the electrons between two atoms.
For
,
The total number of the valence electrons = 2(4) + 1(5) + 3(1) = 16
The Lewis structure is drawn in such a way that the octet of each atom and duet for the hydrogen in the molecule is complete. So,
The Lewis structure is:
H
:
H : C : C : : : N :
:
H
Bond pairs between C and N is 3
<u>So bond pair is 3.</u>
Answer:
False
Explanation:
The attractive force that holds atoms or ions together is called chemical bond.
Answer:
B. topsoil is made entirely of decomposed organic remains
H2CO3->H2O+CO2
H2CO3=>H^+ + CO3^-
