When a marble is dropped into a beaker of water, it sinks to the bottom. Which of the following is the best explanation? a. The surface area of the marble is not large enough for the marble to be held up by the surface tension of the water. b. The mass of the marble is greater than that of the water. c. The marble weighs more than an equivalent volume of the water. d. The force from dropping the marble breaks the surface tension of the water. e. The marble has greater mass and volume than the water. Explain each choice. That is, for choices you did not pick, explain why you feel they are wrong, and justify the choice you did pick.
Chemistry 111 Lecture Notes (Dr. Patton) Chapter 2: Atoms, molecules and ions 2.1- Atomic Theory Atom Derived from the Greek word atomos Small indivisible particles Daltons Atomic Theory Contains 4 postulates (beliefs) 1. All matter is composed of atoms which are small indivisible particles of atoms 2. Elements are samples of matter composed of identical atoms which share the same size and chemical properties. One element has differing atoms compared to all other elements 3. Compounds are composed of two or more elements (Supports Law of Multiple Proportions and Law of Definite Proportions) 4. Atoms of an element can only be rearranged not created or
