We can exemplify with H2O (water)
H= nonmetalic
O= Nonmetalic
A bond with nonmetalic and nonmetalic is covalent bond.
Hope it helps!!

N2 has the optimal bond order of 3. To form N2+, one bonding electron is removed, giving a bond order of 2.5. Similarly, to form N2-, one antibonding electron is added, also giving a bond order of 2.5.
Answer:
2nd option
Explanation:
Molarity is the number of moles of the solute (NaCl) in 1 litre of the solution (NaCl solution).
Given: concentration= 232g/ L
what we are trying to achieve is __mol/ L.
So in 1 litre, we have 232g of NaCl.
To convert mass to mole, we divide it by the Mr.
Given that the Mr is 58g/mol,
number of moles
= 232 ÷58
= 4
Thus, 1 litre has 4 moles of NaCl.
Therefore, the molarity is 4.0 mol/L.
Sound spreads in the medium in the form of concentric spheres known as wave-fronts.
Now, as each wave-front expands, it moves away from the source of the sound and expands at a wider space. This means that its energy decreases and the sound becomes quieter.
So, overall, as sound spreads in spheres:
1- The energy per wave decreases
2- The amplitude of the wave decreases
3- The sound becomes quieter as the sphere moves further away from the source
