A 20 g mixture of propane gas and oxygen is placed in a sealed metal container. An electric spark inside the
container causes the propane and the oxygen to react to produce carbon dioxide and water.
What is true about the process?
The mass of the carbon dioxide and water produced will be less than 20 grams.
The mass of products and reactants will be greater than 20 grams.
The mass of the carbon dioxide and water produced will be greater than 20 grams.
The mass of the reactants and products will remain 20 grams

A 20 g mixture of propane gas and oxygen reacts to form carbon dioxide and water. The mass of the reactants and products will remain 20 grams (Lavoisier's law).

What does Lavoisier's law of mass conservation state?

The total mass of the reactants and the products does not change over the course of a chemical reaction.

A 20 g mixture of propane gas and oxygen reacts to form carbon dioxide and water.

What is true about the process?

  • The mass of the carbon dioxide and water produced will be less than 20 grams. NO. There is no way of telling. If the reaction is completed, it will be exactly 20 g.
  • The mass of products and reactants will be greater than 20 grams. NO. The mass can't be greater than 20 g.
  • The mass of the carbon dioxide and water produced will be greater than 20 grams. NO. The mass can't be greater than 20 g.
  • The mass of the reactants and products will remain 20 grams. YES. According to Lavoisier, the total mass of the system will be 20 g.
