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?(1 point)
In the reaction, 10 atoms of carbon (C) combine with 20 atoms of oxygen (O) to form 10 molecules of carbon dioxide (CO2).
In each molecule of carbon dioxide, there is 1 carbon atom and 2 oxygen atoms. Therefore, in 10 molecules of carbon dioxide, there are:
10 x 1 carbon atoms = 10 carbon atoms
10 x 2 oxygen atoms = 20 oxygen atoms
So, in total, there would be 10 carbon atoms + 20 oxygen atoms = 30 atoms in this reaction.
To determine the total number of atoms present in this reaction, we need to add up the number of atoms from each element. Let's break down the reaction:
10 atoms of carbon (C)
20 atoms of oxygen (O)
Since carbon dioxide has one carbon atom and two oxygen atoms per molecule, we can calculate the total number of atoms by multiplying the number of molecules of carbon dioxide with the number of atoms per molecule:
10 molecules of carbon dioxide (CO2) * (1 carbon atom + 2 oxygen atoms)
This results in:
10 * (1 + 2) = 10 * 3 = 30 atoms
Thus, there are 30 atoms present in this reaction.
To determine the total number of atoms present in the reaction, we need to calculate the sum of the atoms in both the reactants (carbon and oxygen) and the product (carbon dioxide).
The reactants include 10 atoms of carbon (C) and 20 atoms of oxygen (O). Since the atoms are not combined yet, we can add them directly.
Therefore, the total number of atoms in the reactants is 10 + 20 = 30 (C + O atoms).
In the product, 10 carbon dioxide (CO2) molecules are formed. Each molecule consists of one carbon atom and two oxygen atoms. To find the total number of atoms in the product, we multiply the number of molecules by the number of atoms in each molecule.
10 molecules x (1 carbon atom + 2 oxygen atoms) = 10 x 3 = 30 (C + O atoms).
According to the law of conservation of matter, the total number of atoms before and after the reaction remains the same. Therefore, in this reaction, there are 30 atoms present.
