What did antoine lavoisier’s experiments demonstrate

Mass is neither lost nor gained during a chemical change.

Explanation:

Antoine Lavoisier’s Law of Conservation of Mass:

'In a chemical reaction the mass can neither be created and nor be destroyed'.

In a chemical reaction the mass of reactants is equal to the mass of products which means that the mass remain conserved.

For Example: In a chemical reaction:

Mass of reactants = Mass of products

Mass of hydrogen molecule + mass of oxygen molecule = Mass of water

From this we can see that the mass remains conserved in the chemical reaction.

answer; natural resources;

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
