Write the uses/ application of sb2O4( antimony tetroxide)
1. A thin wire of silver (Z=47, A = 107.87, face-centered-cubic, density = 10.49 g/cm³)
is measured at 15 m long and 0.025 m in diameter and has an electrical
resistance of 0.05 2. Assume that each Ag atom contributes three conduction electrons to
the metal.
(a) What is the concentration of conduction electrons in Ag (number/m³)?
(b) What is the mean free time between collisions for the electrons in Ag (in s)?
(c) What is the drift velocity of electrons if an 8 V/m electric field is applied?
(d) Calculate the current density in the wire (in A/m²) from the applied electric
field in part (c).
Heavy metal sulfides like CdS and PbS are often significant components of mine tailings (the piles
of waste and low-grade ores discarded by a mining operation). While these sulfides are quite
insoluble in water (Ksp of CdS = 1 E -27, Ksp of PbS = 3 E -28), over the years rainwater and
snowmelt can slowly dissolve small amounts of these heavy metals, washing them into streams and
other natural waters.
If these mine tailings are located in an area that is impacted by acid rain, would you expect heavy
metal dissolution into natural waters to increase or decrease? Use chemical reactions to justify your
answer.
