Does sulphar weight more after it s burnt?

@ 1 time biggest science alchemy. around time of american revolution french alchemist named antoine lavoisier started asking hard questions. asked "if heat element flows 1 body another, why weight not change? or if heat released in flames, why wood ash weigh less sulfur ash weigh more?" after lot of experiments wrote book, "elements of chemistry" explaining how had measured in experiments. alchemy science of mixing substances, chemistry science of measuring substances.

work of joseph priestly made big difference in question why sulfur ash weighs more sulfur made. mr. priestly invented pump , used distill air several gases. how oxygen discovered, , lot of m. lavoisier's experiments done measure how oxygen in various substances. long time assumed acids had oxygen in them, , more oxygen more corrosive acid. of course didn't take long answer old, old question: sulfur gained weight while burning because combining oxygen produce sulfur dioxide, important step toward forming sulfuric acid.
