May 26, 2017· Old laptops and desktops – Big old desktop computers are about as useful as doorstops, but they still contain small quantities of gold. Pile them up, call us up, and we can explain how to recycle them profitably. And don't forget that gold can be found on printed circuit boards, modem cards, graphics cards, memory chips and other extras that got stuffed into these old machines.

FORMULAS AND NOMENCLATURE OF IONIC AND COVALENT COMPOUNDS Adapted from McMurry/Fay, section 2.10, p. 56 -63 and the 1411 Lab Manual, p. 27 -31. TYPES OF COMPOUNDS Ionic compounds are compounds composed of ions, charged particles that form when an atom (or group of atoms) gains or loses electrons.

Gold (19.30 grams/cubic centimeter) has a much higher density than copper (8.94 grams/cubic centimeter), so if you can successfully pan the copper you will have little trouble panning gold. Before you go out to pan, be sure that you learn more about gold prospecting methods, and about where gold panning is permitted.

Cyclic voltammetry (CV) is a type of potentiodynamic electrochemical measurement. In a cyclic voltammetry experiment, the working electrode potential is ramped linearly versus time. Unlike in linear sweep voltammetry, after the set potential is reached in a CV experiment, the working electrode's potential is ramped in the opposite direction to return to the initial potential.
