When a certain amount of sugar is burned in a crucible, it changes from white sugar to black carbon. Where has the hydrogen and oxygen gone? #Which of Dalton’s postulates about atoms are inconsistent with later observations? Do these inconsistencies mean that Dalton was wrong? #Is Dalton’s model still useful? #Describe the limitations of Dalton’s atomic theory. #Explain the postulates of the modern atomic theory. #List the three fundamental laws of chemistry. #How does the modern atomic theory explain the three fundamental laws of chemistry?
