Question

C3H8+O2-->CO2+H2O



Look at the chemical reaction above. Match each element on the reactant and product side of the equation with the correct number of atoms. After you have counted the atoms on both sides of the equation, decide if the equation is balanced or unbalanced. Some numbers may be used more than once.

Column A
1.
Number of H atoms on the reactant side

:
Number of H atoms on the reactant side

2.
Number of H atoms on the product side

:
Number of H atoms on the product side

3.
Number of C atoms on the reactant side

:
Number of C atoms on the reactant side

4.
Number of C atoms on the product side

:
Number of C atoms on the product side

5.
Number of O atoms on the reactant side

:
Number of O atoms on the reactant side

6.
Number of O atoms on the product side

:
Number of O atoms on the product side

7.
