Propenoic acid, C3H4O2, is a reactive organic liquid that is used in the manufacturing of plastics, coatings, and adhesives. An unlabeled container is thought to contain this liquid. A 0.414-g sample is combusted to produce 0.223 g of water and 0.367 g of carbon dioxide. Calculate the experimental mass % of C and H in the unknown liquid used in the experiment Calculate the experimental mass % of C and H in the unknown liquid used in the experiment.

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.

explanation:

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
