According to the law of conservation of matter, the total number of atoms before and after a reaction must be the same.
In this reaction:
10 atoms of carbon (C) react with 20 atoms of oxygen (O)
The reactants contain a total of 10 + 20 = 30 atoms.
After the reaction, 10 molecules of carbon dioxide (CO2) are formed. Each CO2 molecule contains 1 carbon atom and 2 oxygen atoms.
So, 10 molecules of CO2 contain a total of 10 x 1 = 10 carbon atoms and 10 x 2 = 20 oxygen atoms.
Therefore, the total number of atoms after the reaction is 10 (carbon atoms) + 20 (oxygen atoms) = 30 atoms, which is the same as the total number of atoms before the reaction.
Thus, according to the law of conservation of matter, there are 30 atoms present in this reaction.
Suppose 10 atoms of carbon (c) react with 20 atoms of oxygen(o) to form 10 molecules of carbon dioxide (co2) . According to the law of conservation of matter, how many atoms are present in this reaction
