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?
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.
Before the reaction:
10 atoms of carbon + 20 atoms of oxygen = 30 atoms
After the reaction:
10 molecules of carbon dioxide = 10 atoms of carbon + 20 atoms of oxygen = 30 atoms
Therefore, there are 30 atoms present in this reaction.
According to the law of conservation of matter, the total number of atoms before and after a chemical reaction should be the same.
In this reaction, we have 10 atoms of carbon (C) reacting with 20 atoms of oxygen (O) to form 10 molecules of carbon dioxide (CO2).
To determine the total number of atoms present in this reaction, we need to calculate the number of atoms in each element on both sides of the reaction equation.
Before the reaction:
10 atoms of C + 20 atoms of O
After the reaction:
10 molecules of CO2
In 1 molecule of CO2, we have 1 atom of C and 2 atoms of O. Therefore, in 10 molecules of CO2, we would have:
10 atoms of C and 2 x 10 = 20 atoms of O.
So the total number of atoms before the reaction (10 atoms of C + 20 atoms of O) is equal to the total number of atoms after the reaction (10 atoms of C + 20 atoms of O).
Hence, there are 10 atoms present in this reaction.
To determine how many atoms are present in this reaction, we need to consider the number of atoms in each molecule involved.
In this reaction, we have:
- 10 atoms of carbon reacting with
- 20 atoms of oxygen to produce
- 10 molecules of carbon dioxide (CO2)
Each molecule of carbon dioxide (CO2) contains 1 atom of carbon and 2 atoms of oxygen.
So, in 10 molecules of carbon dioxide, we have a total of:
10 x 1 atom of carbon = 10 atoms of carbon
10 x 2 atoms of oxygen = 20 atoms of oxygen
Therefore, considering the reactants and products, we have a total of:
10 atoms of carbon (from the reactant) + 20 atoms of oxygen (from the reactant) + 10 atoms of carbon (from the product) + 20 atoms of oxygen (from the product) = 60 atoms in total.
According to the law of conservation of matter, the total number of atoms before and after the reaction should remain the same.
