Problem 3

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 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. Justify your choice, and for choices you did not pick, explain what is wrong about them

Step-by-Step Solution:
Step 1 of 3

Intro to Electrochemistry • reduction - gain of electrons • oxidation - loss of electrons • oxidizing agent - reactant that does the oxidizing (being reduced) • reducing agent - reactant that does the reducing (being oxidized) • oxidation numbers/states - number of electrons a component has vs how many it would have as a free atom • rules for oxidation states —oxidation states of pure elements = 0 —oxidation state of single ion = charge of ion —oxidation state of hydrogen = +1 —oxidation state of fluorine = -1 —oxidation state of oxygen = -2 except when bonded with F or another O atom —ex. oxidation state of P in PO4 3-: -3 = x + 4(-2)—>x = +5 half reaction method for balancing redox reactions • —identify w
