A reaction occurs in which carbon combines with oxygen to form carbon dioxide. Is this a chemical reaction or a nuclear reaction, and how do you
know?
A. This is a chemical reaction because only the electrons were rearranged.
B. This is a nuclear reaction, because mass was conserved
C. This is a nuclear reaction because the atoms nuclei changed.
D. This is a chemical reaction because some of the mass was not conserved​

[A] This is a chemical reaction because only the electrons were rearranged.

State that- "It is a combination chemical reaction as carbon combines with oxygen to form carbon dioxide."

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

the answer is   c.) 1575 j.
