It seems that you have missed the necessary options for us to answer this question so I had to look for it. But anyway, here is the answer. If Dr. John Sutherland is correct, the one that was necessary <span> for inert carbon atoms to become part of the chemistry of earth is CYANIDE. Hope this helps.</span>
The amount of CD is 35 g, and the amount of AC is 40 g.
A is the answer. A gas never has a fixed volume or shape
<span>Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms
in order to gain more stability, which is gained by forming a full
electron shell. By sharing their outer most (valence) electrons, atoms can fill up their outer electron shell and gain stability</span>
