The equation P4 + SO2 → 2P4O10 does not demonstrate the law of conservation of mass.
What is law of conservation of mass?
- According to law of conservation of matter, "the mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another."
- The law of conservation of matter is a general law in chemistry applicable for any system closed to all transfers of matter and energy.
- According to this law, the mass of a substance or an object never changes over time, no matter how the constituent parts rearrange themselves. To put it in simple words, the mass can neither be created nor be destroyed.
In equation P4 + SO2 → 2P4O10, the mass of the reactants are not equal to the mass of the products. Therefore, this equation does not obey the law of conservation of mass.
Hence, we can conclude that option C is the answer.
