Zinc is a cheaper and more plentiful metal than brass, so it is often used as a cheaper alternative to brass. However, zinc is not as strong as brass and it is a poorer conductor of electricity. In addition, zinc is more susceptible to corrosion than brass. For these reasons, brass is generally considered to be a better choice for battery ...Web

Lead-zinc deposits are often difficult to classify because clear criteria are lacking. In recent years, new tools, such as Cd and Zn isotopes, have been used to better understand the ore-formation processes and to classify Pb-Zn deposits. Herein, we investigate Cd concentrations, Cd isotope systematics and Zn/Cd ratios in sphalerite …Web

Solution. We can solve the problem in one of two ways: (1) compare the relative positions of the four possible reductants with that of the Ag 2 S/Ag couple in Table 1 or (2) compare E° for each species with E° for the Ag 2 S/Ag couple (−0.69 V). A The species in Table 1 are arranged from top to bottom in order of increasing reducing strength.Web
