As part of an experiment, a student burns propane (c3h8) to produce carbon dioxide (co2) and water (h2o). she remembers that she must follow the law of conservation of matter when writing a balance chemical equation. which of these equations adheres to the law of conservation of matter? a) c3h8 + o2 -> co2 + h2o b) c3h8 + o2 -> 3co2 + h2o c) c3h8 + 3o2 -> co2 + 4h2o d) c3h8 + 5o2 -> 3co2 + 4h2o

The correct answer is: D) C3H8 + 5O2 -> 3CO2 + 4H2O

The law of conservation of mass (matter) states that the mass of the system must remain constant over time. So, the mass of the chemical components before the reaction must be equal to the mass of the components after the reaction, according to this law.
