Question

Which postulate of Dalton's theory is consistent with the following observation concerning the weights of reactants and products? When 100 grams of solid calcium carbonate is heated, 44 grams of carbon dioxide and 56 grams of calcium oxide are produced.

a. Atoms of one element differ in properties from atoms of all other elements.b. A compound consists of atoms of two or more elements combined in a small, whole-number ratio.c. Atoms are neither created nor destroyed during a chemical change.

Answer 1

C

Step-by-step explanation:

In the above question, we can see that there is a direct conversion via rearrangements between the atoms. No new atoms were created or destroyed. What simply happened was that the individual atoms picked up new partners and left their original compound to form new compounds.

Hence, the postulate of Dalton agreeable with this total conversion is that atoms can neither be created nor destroyed but can undergo a form of rearrangement to give ris e to new compounds
