Which of the following equations demonstrates the Law of Conservation of Mass? (1 point)

• CH4 + 02 → CO2 + HO
• CH4 + 02 → C + 2H20
• CH + 02 → CO2 + H20
• CH4 + 02 → CO2 + H20

1 answer

The equation that demonstrates the Law of Conservation of Mass is:

CH4 + O2 → CO2 + H2O

In this equation, the number of atoms of each element is the same on both sides of the equation, indicating that mass is conserved during the reaction.
