In the balanced chemical equation, below, determine what the coefficient and the subscript represent in 4CO2.
Choose ALL the answers that are correct.
a
The 2 subscript represents 2 atoms of oxygen in each molecule.
b
The 2 subscript represents 2 oxygen molecules.
c
The 4 coefficient represents 4 molecules of carbon dioxide.
d
The 4 coefficient represents 4 atoms of carbon in each molecule.
a
The 2 subscript represents 2 atoms of oxygen in each molecule.
c
The 4 coefficient represents 4 molecules of carbon dioxide.
The correct answers are:
a) The 2 subscript represents 2 atoms of oxygen in each molecule.
c) The 4 coefficient represents 4 molecules of carbon dioxide.
The correct answers are:
a. The 2 subscript represents 2 atoms of oxygen in each molecule.
c. The 4 coefficient represents 4 molecules of carbon dioxide.
Explanation:
In the balanced chemical equation, 4CO2, the coefficient (4) represents the number of molecules of carbon dioxide. This means that there are 4 individual carbon dioxide molecules present in the reaction.
On the other hand, the subscript (2) represents the number of atoms of oxygen in each carbon dioxide molecule. In this case, there are 2 atoms of oxygen in each carbon dioxide molecule. So, in a total of 4 molecules, there would be a total of 4 x 2 = 8 atoms of oxygen.
