Carbon is found in all known forms of life. which statement best describes why carbon is uniquely suited to forming macromolecules such as those found in living organisms?
a. carbon forms large compounds that are not chemically reactive.
b. carbon forms weak bonds with other atoms that can be easily broken to release energy.
c. carbon forms strong, stable bonds with up to four other atoms, including other carbon atoms.
d. carbon forms large, flat compounds that have increased surface area for reactions.

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

a) the particles of the chair are strongly held together.
