A stove needs gas to burn (I only have one off the top of my head, sorry :/)
I guess you could call them that. In chemistry, we call them Metalloids though.
We know that
pH = -log[H+]
the pH value falls in between 0- 7 for acids
As the pH value increases the concentration of [H+] increases.
similarly as the value of pH approaches 0, the concentration of H+ increases
The solution said to become more acidic
Also
[H+] X [OH-] = 10^-14
Thus pH + pOH = 14
hence the concentration of OH- decreases as the pH approaches zero
Mg₃N₂ + 6H₂O = 3Mg(OH)₂ + 2NH₃
Be a chemist. Lol. Lessen waste, make chemicals more efficient, cure diseases... and stuff :)
