Option B. Humus. Its dark color is due to the high content of carbon.
The pH scale for acids and bases ranges from 1 - 14. The answer is letter C. The rest of the choices do not answered the question above. There are quite a few relationships between [H+] and [OH−] ions. And because there is a large range of number between 10 to 10-15 M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, [H+ ][OH- ] = 10-14. From here we can derive the values of each concentration.
-log[H+ ] + -log[OH- ] = -log[10-14]
pH + pOH = 14
So pH = 14 – pOH and pOH = 14 –
pH
It would be B.

IM in 7th dont ask me bro
Answer:
Ionic bond is bond between a metal and non metal , metallic bonding happens between positive metals ions and negative electrons in a metal
Explanation:
ionic Bond is the transfer of electrons between a metal and non metal due to strong electrostatic force of attraction between positive metal ions and negative non metal ions
in metallic bonding , there is a force of attraction between positive metal ions and the sea of electrons surrounding it
