Answer:
30
According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.
LAW OF CONSERVATION OF MATTER:
The law of conservation of matter states that matter can neither be created nor produced in a chemical reaction.
This further means that the amount of matter in the reactant of a reaction must equate that of the products.
Hence, if 10 atoms of carbon (C) react with 20 atoms of oxygen (O), there will be 10 + 20 = 30 atoms of product in this reaction.
Therefore, According to the Law of Conservation of Matter, there will be 30 atoms of product in the reaction.
