In the balanced chemical equation, below, determine what the coefficient and the subscript represent in 6H2O.
Choose ALL the answers that are correct.
4CO2 + 6H20 → 2C2H6 + 7O2
a
The 6 coefficient represents 6 atoms in each water molecule.
b
The 6 coefficient represents 6 molecules of water.
c
The 2 subscript represents 2 atoms in each water molecule.
d
The 2 subscript represents 2 water molecules.
b
The 6 coefficient represents 6 molecules of water.
c
The 2 subscript represents 2 atoms in each water molecule.
The correct answers are:
b) The 6 coefficient represents 6 molecules of water.
d) The 2 subscript represents 2 water molecules.
In the balanced chemical equation 4CO2 + 6H2O → 2C2H6 + 7O2, the coefficient and the subscript in 6H2O can be explained as follows:
a) The coefficient 6 represents the number of molecules of water. So, by multiplying the coefficient 6 by Avogadro's number (6.022 × 10^23), you can calculate the number of water molecules.
b) Therefore, the correct answer is that the 6 coefficient represents 6 molecules of water.
c) The subscript 2 represents the number of hydrogen atoms in each water molecule.
d) Thus, the correct answer is that the 2 subscript represents 2 atoms in each water molecule.
Therefore, the correct answers are b and c.
