According to the law of conservation of matter, matter cannot be created or destroyed in a chemical reaction, only rearranged. Therefore, the number of atoms before the reaction must equal the number of atoms after the reaction.
We start with 1 atom of carbon, 20 atoms of oxygen, and no carbon dioxide molecules. After the reaction, we have 10 molecules of carbon dioxide, which contains 1 carbon atom and 2 oxygen atoms per molecule.
Therefore, the number of carbon atoms after the reaction is 10 (since there are 10 carbon dioxide molecules) and the number of oxygen atoms after the reaction is 20*2*10 = 400 (since there are 2 oxygen atoms per carbon dioxide molecule multiplied by the total number of carbon dioxide molecules).
In total, there are 10 carbon atoms + 400 oxygen atoms = 410 atoms present in this reaction.
Supposed an atoms of carbon reacts with 20 atoms of oxygen to form 10 molecules of carbon dioxide, according to the law of conservation of matter how many atoms are present in this reaction
