suppose 10 atoms of carbon react 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
In this reaction, 10 atoms of carbon and 20 atoms of oxygen combine to form 10 molecules of carbon dioxide.
Each molecule of carbon dioxide (CO2) contains 1 carbon atom and 2 oxygen atoms. So, in 10 molecules of CO2, there are a total of 10 carbon atoms and 20 oxygen atoms.
Therefore, the total number of atoms present in this reaction is:
10 (carbon atoms) + 20 (oxygen atoms) = 30 atoms.
