Hey everyone in this question, we need to identify the statement that follows Dalton's atomic theory and explain why Statement A. is stating that water is formed when hydrogen oxygen combined in a 1-2. ratio. We want to recall that atoms combine in whole number ratios. And so we would say that therefore this is an inconsistent statement to Dalton's theory. And so we would rule out choice A choice B states that copper can be made from iron atoms. We want to recall that you can't do stuff like this, you can't make atoms of one element from another. And so therefore this is inconsistent with Dalton's atomic theory. So we can rule out Choice B. Moving to statement, see it says that all atoms of zinc have the same mass and properties. And so we would recall that no matter how many atoms of zinc we have in a molecule. This statement is going to be consistent with Dalton's theory because atoms of a given element have the same mass and properties. So this is exactly from Dalton's atomic theory and we would agree with choice C. So we can definitely say it's consistent. Moving onto Choice D. We have carbon and nitrogen atoms have different physical properties but have identical chemical properties. And this statement totally contradicts statements. See statement C. Is consistent with Dalton's theory. Then, statement D. Is definitely going to be inconsistent again, atoms of an of a given element have the same mass and other properties. And so we would rule out choice D. So the only correct choice to complete this example is Choice C. All atoms of a given element, like zinc will have the same mass and other similar properties. So this is in line with Dalton's atomic theory, and this will complete this example as our final answer. If you have any questions, please leave them down below, and I will see everyone in the next practice video.

Sulfur and oxygen form both sulfur dioxide and sulfur trioxide. When samples of these are decomposed, the sulfur dioxide produces 3.49 g oxygen and 3.50 g sulfur, while the sulfur trioxide produces 6.75 g oxygen and 4.50 g sulfur. Calculate the mass of oxygen per gram of sulfur for each sample and show that these results are consistent with the law of multiple proportions.

Sulfur and fluorine form several different compounds including sulfur hexafluoride and sulfur tetrafluoride. Decomposition of a sample of sulfur hexafluoride produces 4.45 g of fluorine and 1.25 g of sulfur, while decomposition of a sample of sulfur tetrafluoride produces 4.43 g of fluorine and 1.87 g of sulfur. Calculate the mass of fluorine per gram of sulfur for each sample and show that these results are consistent with the law of multiple proportions.

Textbook Question

Which statements are inconsistent with Rutherford's nuclear theory as it was originally stated? Why? a. Since electrons are smaller than protons, and since a hydrogen atom contains only one proton and one electron, it must follow that the volume of a hydrogen atom is mostly due to the proton. b. A nitrogen atom has 7 protons in its nucleus and 7 electrons outside of its nucleus. c. A phosphorus atom has 15 protons in its nucleus and 150 electrons outside of its nucleus. d. The majority of the mass of a fluorine atom is due to its 9 electrons.
