Question

The diagram below shows the reactants and products of a chemical reaction. What property of reactions does this diagram illustrate?
Carbon + Oxygen arrow Carbon dioxide

A. Energy is always produced in a synthesis reaction.

B. Atoms are always conserved during chemical reactions.

C. The number of bonds always increases in a chemical reaction.

D. Only gases can react to produce gases in a chemical reaction.

Answer 1

Based on the chemical reaction, Carbon reacts with Oxygen would yield Carbon Dioxide, we can imply that the "Atoms are always conserved during chemical reactions." It is one of the fundamental concepts in chemistry wherein the mass is always conserved in a reaction since it can't be created nor destroyed.
