Suppose 10 atoms of carbon reacts with 20 atoms of oxygen to form 10 molecules of carbon dioxide, according to the law of conversation of the matter how many atoms are present in the reaction
According to the law of conservation of matter, the number of atoms present before and after a chemical reaction should be the same.
In this reaction, we have 10 atoms of carbon and 20 atoms of oxygen reacting to form 10 molecules of carbon dioxide.
One molecule of carbon dioxide (CO2) contains one atom of carbon and two atoms of oxygen.
Therefore, the number of atoms present in the reaction is:
10 atoms of carbon + (10 molecules of CO2 x 1 atom of carbon per molecule) + (10 molecules of CO2 x 2 atoms of oxygen per molecule) = 10 + 10 + 20 = 40 atoms in total.
According to the law of conservation of matter, the number of atoms before the reaction must be equal to the number of atoms after the reaction.
In this chemical reaction, we have 10 atoms of carbon and 20 atoms of oxygen reacting to form 10 molecules of carbon dioxide (CO2).
Each carbon dioxide molecule (CO2) contains 1 carbon atom and 2 oxygen atoms. Therefore, 10 molecules of carbon dioxide contain 10 carbon atoms and 20 oxygen atoms.
So, the total number of atoms before the reaction is:
10 carbon atoms + 20 oxygen atoms = 30 atoms.
Therefore, there are 30 atoms present in the reaction according to the law of conservation of matter.
To determine the number of atoms present in the reaction, we need to consider the balanced chemical equation of the reaction. From the given information:
10 atoms of carbon react with 20 atoms of oxygen to form 10 molecules of carbon dioxide.
The balanced chemical equation for the reaction can be written as:
10C + 20O₂ → 10CO₂
From the equation, we can see that 10 carbon atoms react with 20 oxygen atoms to produce 10 molecules of carbon dioxide.
Now, to calculate the total number of atoms present, we need to consider the number of atoms in each molecule of carbon dioxide.
In one molecule of carbon dioxide (CO₂), there is one carbon atom (C) and two oxygen atoms (O). Since we have 10 molecules of carbon dioxide, we can multiply the number of atoms in one molecule by 10 to get the total number of atoms:
Number of carbon atoms = 1 carbon atom/molecule × 10 molecules = 10 carbon atoms
Number of oxygen atoms = 2 oxygen atoms/molecule × 10 molecules = 20 oxygen atoms
Therefore, in the given reaction, there are a total of 10 carbon atoms and 20 oxygen atoms.
