Question

Given the chemical equation: C2H4 + O2  CO2 + H2O Balance the chemical equation. Explain how the balanced chemical equation agrees with the law of conservation of mass.

Answer 1

Answer: C2H4 + 3O2  2CO2 + 2H2O

Explanation: Since the exact same amount of atoms is on both sides, no mass or matter is lost which agrees with the law of conservation of mass. This law states that The law of conservation of mass is that, in a closed or isolated system, matter cannot be created or destroyed. It can change forms but is conserved.
