Nthis example we will use the quantization of charge to determine the number of excess electrons in an object. (a) a large plastic block has a net charge of −1.0μc=−1.0×10−6c. how many more electrons than protons are in the block? (b) when rubbed with a silk cloth, a glass rod acquires a net positive charge of 1.0 nc. if the rod contains 1.0 mole of molecules, what fraction of the molecules have been stripped of an electron? assume that at most one electron is removed from any molecule.

In an energy pyramid, which level has the most available energy?

Ageochemist examines a piece of metal that he found in the soil. he performs tests to identify the metal from its density, electrical conductivity, and melting point. which statement best describes his investigation? a. he is determining physical properties that are sufficient to identify the metal.b. he is determining chemical properties that are sufficient to identify the metal.c. he is determining physical properties that are insufficient to identify the metal.d. he is determining chemical properties that are insufficient to identify the metal.
