See work below.

Work Step by Step

a. Dalton's first theory states that atoms make up all matter, and that atoms can not be divided nor destroyed. Through this, the law of conservation of mass (mass in a reaction can not be destroyed nor created) is supported. b. Dalton's fourth theory states that a chemical reaction only rearranges atoms. This supports the law of definite proportions, which states that the mass of the reactants (given by atoms) equals the mass of the products. c. Dalton's third theory states that compounds are combination of two or more different atoms, which both have their own fixed masses (given by Dalton's third law). This supports the law of multiple proportions (when two elements combine into a compound, the different atoms with fixed masses have a ratio of small whole numbers).
