b.He used a scientific method to conduct his experiment.
c.He wrote his results down as four parts of the atomic theory.
d.He verified Democritus’s idea that matter was composed of atoms.

Answer 1

The answer is (A He reinterpreted and retested Joseph Proust’s results.

Answer 2

The correct is the option A

Step-by-step explanation:Dalton developed the law of multiple proportions (first presented in 1803) by studying and expanding upon the works of Antoine Lavoisier and Joseph Proust.Proust had studied tin oxides and found that their masses were either 88.1% tin and 11.9% oxygen or 78.7% tin and 21.3% oxygen (these were tin(II) oxide and tin dioxide respectively). Dalton noted from these percentages that 100g of tin will combine either with 13.5g or 27g of oxygen; 13.5 and 27 form a ratio of 1:2. Dalton found an atomic theory of matter could elegantly explain this common pattern in chemistry – in the case of Proust’s tin oxides, one tin atom will combine with either one or two oxygen atoms.
